I'm trying to use xsl:key to lookup items in an external XML document, using the XSL document() function. I am able to get the xsl:key part to work if, instead of using document(), I just merge the two XML files (using XmlDocument in C#). However both XML files are very large, and I'm starting to get "out of memory" errors in some cases. Also I need to be able to use xls:key, otherwise the process takes hours.
In XSLT 2.0, I believe you can do something like this:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="lookupDoc" select="document('CodeDescriptions.xml')" />
<xsl:key name="LookupDescriptionByCode" match="Code/#description" use="../#code" />
<xsl:template match="ItemCode">
<xsl:call-template name="MakeSpanForCode">
<xsl:with-param name="code" select="text()" />
</xsl:call-template>
</xsl:template>
<xsl:template name="MakeSpanForCode">
<xsl:param name="code" />
<xsl:element name="span">
<xsl:attribute name="title">
<xsl:value-of select="$lookupDoc/key('LookupDescriptionByCode', $code)" />
</xsl:attribute>
<xsl:value-of select="$code" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
How do you accomplish this in XSLT 1.0 though?
You have two possibilities:
without key
<xsl:template name="MakeSpanForCode">
<xsl:param name="code" />
<xsl:element name="span">
<xsl:attribute name="title">
<xsl:value-of select="$lookupDoc/*/Code[#code = $code]/#description" />
</xsl:attribute>
<xsl:value-of select="$code" />
</xsl:element>
</xsl:template>
with key
The key definition applies to all documents, but you need to change the context node before using the key() function:
<xsl:template name="MakeSpanForCode">
<xsl:param name="code" />
<xsl:element name="span">
<xsl:attribute name="title">
<!-- trick: change context node to external document -->
<xsl:for-each select="$lookupDoc">
<xsl:value-of select="key('LookupDescriptionByCode', $code)"/>
</xsl:for-each>
</xsl:attribute>
<xsl:value-of select="$code" />
</xsl:element>
</xsl:template>

I'm trying to move space-delimited tokens from one attribute to another in XSLT-2.0. For example, given
<!-- SOURCE DOCUMENT -->
<?xml version="1.0" encoding="UTF-8"?>
<root>
<p class="foo"/>
<p class="foo bar baz"/>
<p class="foo bar baz" outputclass="BAR"/>
<p class="foo bar baz" outputclass="BAR HELLO"/>
</root>
I need to move #class="foo" to #outputclass="FOO" and #class="bar" to #outputclass="BAR", deleting the source attribute if it becomes empty and augmenting the target attribute if it exists (simple token-set operations):
<!-- RESULTING DOCUMENT -->
<?xml version="1.0" encoding="UTF-8"?>
<root>
<p outputclass="FOO"/>
<p class="baz" outputclass="FOO BAR"/>
<p class="baz" outputclass="FOO BAR"/>
<p class="baz" outputclass="FOO BAR HELLO"/>
</root>
I think I have everything figured out except the actual token-moving part. Every direction I go down ends up complicated and broken, and I feel like XSLT-2.0 surely has a simple approach that I'm missing.
Here's what I have so far:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:mine="mine:local"
exclude-result-prefixes="xs"
version="2.0">
<!-- baseline identity transform -->
<!-- (for non-elements - attributes, whitespace PCDATA, etc.) -->
<xsl:template match="#*|(node() except *)">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<!-- for element nodes, remap attributes then copy element -->
<xsl:template match="*">
<!-- get original attribute sequence -->
<xsl:variable name="atts1" select="#*"/>
<!-- use our function to remap two attribute tokens -->
<xsl:variable name="atts2" select="mine:remap($atts1, 'class', 'foo', 'outputclass', 'FOO')"/>
<xsl:variable name="atts3" select="mine:remap($atts2, 'class', 'bar', 'outputclass', 'BAR')"/>
<!-- stuff updated attribute sequence into element -->
<xsl:copy>
<xsl:sequence select="$atts3"/>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
<!-- remap #from_att~="$from_token" to #to_att~="$to_token" -->
<xsl:function name="mine:remap">
<xsl:param name="orig_atts"/>
<xsl:param name="from_att"/>
<xsl:param name="from_token"/>
<xsl:param name="to_att"/>
<xsl:param name="to_token"/>
<!-- ******** TOKEN-MOVING MAGIC!?! ******** -->
<xsl:sequence select="$orig_atts"/>
</xsl:function>
</xsl:stylesheet>
Basically I need to figure out how TOKEN-MOVING MAGIC!?! can move a single token (including deletion of empty "from" attributes). I've searched quite a bit but I haven't seen this particular problem covered.
Edit: The number and names of attributes to remap can be anything, and their values are case-sensitive. It's the magic inside the mine:remap function to remap a single value in an attribute sequence that I'm looking for.
Edit: The reason for approaching attribute modification with a function is that we have a number of different token remappings to apply to different files, and I hoped to allow our non-XSLT-savvy users to easily adjust the remappings to their needs. I was unable to figure out how to provide similar generalization with a template-matching-based approach.
Thanks!
Here is a short XSLT 2.0 solution (just 26 lines):
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="p/#class[tokenize(., ' ') = ('foo', 'bar')]">
<xsl:if test="tokenize(., ' ')[not(. = ('foo', 'bar'))]">
<xsl:attribute name="class"
select="string-join(tokenize(., ' ')[not(. = ('foo', 'bar'))], ' ')"/>
</xsl:if>
<xsl:attribute name="outputclass" select=
"upper-case(string-join(
(
tokenize(., ' ')[. = ('foo', 'bar')],
tokenize(../#outputclass, ' ')
[not(lower-case(.) = tokenize(current(), ' '))]
),
' '
)
)"/>
</xsl:template>
<xsl:template match="p/#outputclass[../#class[tokenize(., ' ') = ('foo', 'bar')]]"/>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<root>
<p class="foo"/>
<p class="foo bar baz"/>
<p class="foo bar baz" outputclass="BAR"/>
<p class="foo bar baz" outputclass="BAR HELLO"/>
</root>
the wanted, correct result is produced:
<root>
<p outputclass="FOO"/>
<p class="baz" outputclass="FOO BAR"/>
<p class="baz" outputclass="FOO BAR"/>
<p class="baz" outputclass="FOO BAR HELLO"/>
</root>
Update:
Here is the same transformation with almost everything parameterized, as requested in a comment by the OP, just 32 lines:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:param name="pfromName" select="'class'"/>
<xsl:param name="ptoName" select="'outputclass'"/>
<xsl:param name="pTokens" select="'foo', 'bar'"/>
<xsl:param name="pnewNames" select="'FOO', 'BAR'"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="p/#*[name() = $pfromName][tokenize(., ' ') = $pTokens]">
<xsl:if test="tokenize(., ' ')[not(. = $pTokens)]">
<xsl:attribute name="{$pfromName}"
select="string-join(tokenize(., ' ')[not(. = $pTokens)], ' ')"/>
</xsl:if>
<xsl:attribute name="{$ptoName}" select=
"upper-case(string-join(
(
tokenize(., ' ')[. = $pTokens],
tokenize(../#*[name()=$ptoName], ' ')
[not(lower-case(.) = tokenize(current(), ' '))]
),
' '
)
)"/>
</xsl:template>
<xsl:template
match="p/#*[name()=$ptoName][../#*[name()=$pfromName][tokenize(., ' ') = $pTokens]]"/>
</xsl:stylesheet>
Update2:
Here is a completely parameterized XSLT 2.0 transformation (not using the upper-case() and lower-case() functions), just 37 lines:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:param name="pfromName" select="'class'"/>
<xsl:param name="ptoName" select="'outputclass'"/>
<xsl:param name="pTokens" select="'foo', 'bar'"/>
<xsl:param name="pnewNames" select="'FOO', 'BAR'"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="p/#*[name() = $pfromName][tokenize(., ' ') = $pTokens]">
<xsl:if test="tokenize(., ' ')[not(. = $pTokens)]">
<xsl:attribute name="{$pfromName}"
select="string-join(tokenize(., ' ')[not(. = $pTokens)], ' ')"/>
</xsl:if>
<xsl:attribute name="{$ptoName}" select=
"string-join(
distinct-values(
(for $token in tokenize(., ' ')[. = $pTokens],
$n in 1 to count($pTokens),
$ind in $n[$token eq $pTokens[$n]]
return $pnewNames[$ind]
,
tokenize(../#*[name()=$ptoName], ' ')
)
),
' '
)
"/>
</xsl:template>
<xsl:template
match="p/#*[name()=$ptoName][../#*[name()=$pfromName][tokenize(., ' ') = $pTokens]]"/>
</xsl:stylesheet>
In the following sample I have tried to delegate as much as possible to templates:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="#all"
version="3.0">
<xsl:param name="tokens" as="xs:string*"
select="'foo', 'bar'"/>
<xsl:param name="collation" as="xs:string">http://www.w3.org/2005/xpath-functions/collation/html-ascii-case-insensitive</xsl:param>
<xsl:mode on-no-match="shallow-copy"/>
<xsl:template match="*[#class][exists($tokens[contains-token(current()/#class, ., $collation)])]">
<xsl:copy>
<xsl:variable name="new-att" as="attribute()">
<xsl:attribute name="outputclass"/>
</xsl:variable>
<xsl:apply-templates select="#*, $new-att[not(current()/#outputclass)]">
<xsl:with-param name="tokens-found"
select="$tokens[contains-token(current()/#class, ., $collation)]"/>
</xsl:apply-templates>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="#class">
<xsl:param name="tokens-found"/>
<xsl:variable name="remaining-tokens" select="tokenize(., ' ')[not(. = $tokens-found)]"/>
<xsl:if test="exists($remaining-tokens)">
<xsl:attribute name="{name()}" select="$remaining-tokens"/>
</xsl:if>
</xsl:template>
<xsl:template match="#outputclass">
<xsl:param name="tokens-found"/>
<xsl:variable name="new-tokens" select="$tokens-found[not(contains-token(current(), ., $collation))]"/>
<xsl:attribute name="{name()}" select="$new-tokens, ."/>
</xsl:template>
</xsl:stylesheet>

I haven't implemented the upper-case transformation of the tokens to be moved, I guess it should be easy to add that.
The code uses XSLT 3 with XPath 3 and the function https://www.w3.org/TR/xpath-functions/#func-contains-token but it has a definition in the spec that you could use in a user-defined XSLT 2 function. It is of course also easy to not declare the identity transformation using xsl:mode but by spelling it out.
XSLT 3 is available with Saxon 9.8 or later for Java and .NET, with Saxon-C for C/C++, with bindings for PHP and Python and with Saxon-JS 2 inside of modern web browsers and for Node.js.
Here is what I ended up with for the mine:remap() function:
<!-- remap #from_att~="$from_token" to #to_att~="$to_token" -->
<xsl:function name="mine:remap">
<xsl:param name="orig_atts" as="attribute()*"/>
<xsl:param name="from_att"/>
<xsl:param name="from_token"/>
<xsl:param name="to_att"/>
<xsl:param name="to_token"/>
<!-- get tokenized list of values of "from" attributes -->
<xsl:variable name="from_att_values" select="tokenize($orig_atts[name() = $from_att], ' ')"/>
<xsl:choose>
<!-- does the "from" attribute contain our value to replace? -->
<xsl:when test="$from_att_values = $from_token">
<!-- if so, iterate through attributes to preserve their order -->
<xsl:for-each select="$orig_atts">
<xsl:choose>
<!-- if "from" and "to" attributes are the same, replace $from_token with $to_token in-place -->
<xsl:when test="(name(.) = $from_att) and ($from_att = $to_att)">
<xsl:attribute name="{name(.)}" select="for $t in $from_att_values
return ($t[$t != $from_token], $to_token[$t = $from_token])"/>
</xsl:when>
<!-- if "from" attribute, define with $from_token value removed -->
<xsl:when test="name(.) = $from_att">
<xsl:variable name="new_from_att_values" select="$from_att_values[not(. = $from_token)]"/>
<xsl:if test="count($new_from_att_values) > 0">
<xsl:attribute name="{$from_att}" select="$new_from_att_values"/>
</xsl:if>
</xsl:when>
<!-- if "to" attribute, define with $to_token value added -->
<xsl:when test="name(.) = $to_att">
<xsl:attribute name="{$to_att}" select="distinct-values((tokenize(., ' '), $to_token))"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
<!-- if there was no "from" attribute to modify above, create it here -->
<xsl:if test="not($orig_atts[name() = $to_att])">
<xsl:attribute name="{$to_att}" select="$to_token"/>
</xsl:if>
</xsl:when>
<!-- if not, return original attributes -->
<xsl:otherwise>
<xsl:sequence select="$orig_atts"/>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
I iterate through the attributes to preserve their order, then I use xsl:choose to handle the from (remove a token), to (add a token), or other (copy) attributes.
I have a two phases XSLT transformation with xml as output. When I set a breakpoint in one of templates during my first phase and start my xslt transformation in debug mode with XML Spy Professional 2020, I can see an xml structure in XSL Output.xml as the processed result before my template with breakpoint is applied.
My question is, is there a way in one template in the same phase to access this structure, which is a temporary result of transformation, which is not yet completed?
For development I use XML Spy Professional 2020 and for transformation in application I use Saxon Professional Edition SaxonPE9-9-1-3J.
My problem is following:
Input is a plain text https://gist.github.com/jia2/35143e79213864153b57ad0323a440a8#file-input-txt
Based on this format rules https://gist.github.com/jia2/76d676b90935cb7f33f5028180557af3,
the expected XML output like this:

My xslt template https://gist.github.com/jia2/5f7387e549e6f83601dbfac23ceb3acf is reading this format.xml as input and the plain text is passed by as parameter. It works for some inputs. but it will fail, when the value, which is used for marking begin of "StructFormat", exist in other positions.
For example:
<StructFormat name='HandoverTakeover' delimOptional='n' optional='y'>
<TagField type='String' value='U1 '/>
This means, StructFormat should be generated, when the input has "U1 " at a position. Now I'm just checking if input text contains "U1 " (<xsl:when test="$this/TagField and not(contains($msg, $this/TagField/#value)) ">), but this is not enough, I need to check, if the "U1 " comes in the "right" position range, not in the whole input.
I though if I can access currently build result tree, I can count the length until now to to cut the text before this position where I am checking.
Thanks

XSLT is a functional language; it therefore disallows operations whose result would depend on the order of execution. The fact that particular processors organise the processing in a particular way (even when two different processors choose the same strategy) doesn't mean it is something that can be relied on; in a few years time, for example, parallel execution strategies may be much more common.
More specifically, the fact that the two phases of your transformation are executing "concurrently" (one starts before the other finishes) is an internal optimization that you cannot exploit or rely on, and this is by design.
No doubt the transformation you are trying to effect can be achieved in some completely different way within the paradigm of a declarative functional language. I haven't studied the particular problem; like many people answering questions on StackOverflow, I'm not prepared to follow links to code that's off-site.
So I've been banging my head against the wall for a while and am looking for some help. I'm trying to create a new itemstyle in sharepoint designer that basically checks each item in a task list and then tallies up the total number of Completed, In Progress, and Not Started statuses. The problem is to my knowledge, xsl doesn't have mutable variables. What I have so far is this:
<xsl:variable name="sChk">
<xsl:value-of select="#Status"/>
</xsl:variable>
<xsl:for-each select="#Status">
<xsl:if test="$sChk = 'Completed' ">
<!-- Add to Completed Counter -->
</xsl:if>
<xsl:if test="$sChk = 'In Progress' ">
<!-- Add to In Progress Counter -->
</xsl:if>
<xsl:if test="$sChk = 'Not Started' ">
<!-- Add to Not Started Counter -->
</xsl:if>
<br/>
</xsl:for-each>
Out Of Loop:
Total Completed: <!-- Completed Value -->
Total In Progress: <!-- In Progress Value -->
Total Not Started: <!-- Not Started Value -->
Any and all help would be greatly appreciated, thanks!
EDIT: So I've also tried this recursive method as well but this isn't working either...
<xsl:param name="cCount" select="0"/>
<xsl:param name="ipCount" select="0"/>

You are correct in that in XSLT variables are immutable. What you need to use in your case those is the count function, which counts up all the items in a node-set. Something like this:
<xsl:variable name="completed" select="count(task[#Status='Completed'])" />
<xsl:variable name="inprogress" select="count(task[#Status='In Progress'])" />
<xsl:variable name="notstarted" select="count(task[#Status='Not Started'])" />
Total: <xsl:value-of select="$completed + $inprogress + $notstarted" />
Of course, you would need to replace 'task' with what ever element name you are using in your XSLT.
Without seeing your XML, it is hard to give a precise answer, but as an example, consider the following XML
<tasklist>
<task status="Completed" />
<task status="Completed" />
<task status="In Progress" />
</tasklist>
Then the XSLT (to get totals only), would look like this
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="tasklist">
<xsl:variable name="completed" select="count(task[#Status='Completed'])" />
<xsl:variable name="inprogress" select="count(task[#Status='In Progress'])" />
<xsl:variable name="notstarted" select="count(task[#Status='Not Started'])" />
Total: <xsl:value-of select="$completed + $inprogress + $notstarted" />
</xsl:template>
</xsl:stylesheet>
Notice how you need to be positioned on the parent element of all the individual 'task' elements here. As an alternative, you can do something like this...
<xsl:variable name="completed" select="count(//task[#Status='Completed'])" />
Which would count task elements wherever they are in the XML.
You could even do the following, if you really didn't know the element name, but were sure there were no other elements with a 'Status' attibute:
<xsl:variable name="completed" select="count(//*[#Status='Completed'])" />
I have a Content Query Webpart (CQWP) pulling the URL and title from a News links list. The CQWP uses the XSLT style Orange.News.Links defined in ItemStyle.xsl.
I need to sort the title #Title0 field as commented out below because it causes an error.
Does anyone know whats causing this error? - Many Thanks. The XSLT code is below:
<xsl:template name="Orange.News.Links" match="Row[#Style='Orange.News.Links']" mode="itemstyle">
<xsl:param name="CurPos" />
<xsl:param name="Last" />
<xsl:variable name="SafeLinkUrl">
<xsl:call-template name="OuterTemplate.GetSafeLink">
<xsl:with-param name="UrlColumnName" select="'LinkUrl'"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="DisplayTitle">
<xsl:call-template name="OuterTemplate.GetTitle">
<xsl:with-param name="Title" select="#URL"/>
<xsl:with-param name="UrlColumnName" select="'URL'"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="LinkTarget">
<xsl:if test="#OpenInNewWindow = 'True'" >_blank</xsl:if>
</xsl:variable>
<xsl:variable name="SafeImageUrl">
<xsl:call-template name="OuterTemplate.GetSafeStaticUrl">
<xsl:with-param name="UrlColumnName" select="'ImageUrl'"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="Header">
<xsl:if test="$CurPos = 1">
<![CDATA[<ul class="list_Links">]]>
</xsl:if>
</xsl:variable>
<xsl:variable name="Footer">
<xsl:if test="$Last = $CurPos">
<![CDATA[</ul>]]>
</xsl:if>
</xsl:variable>
<xsl:value-of select="$Header" disable-output-escaping="yes" />
<li>
<a>
<xsl:attribute name="href">
<xsl:value-of select="substring-before($DisplayTitle,', ')"></xsl:value-of>
</xsl:attribute>
<xsl:attribute name="title">
<xsl:value-of select="#Description"/>
</xsl:attribute>
<!-- <xsl:sort select="#Title0"/> -->
<xsl:value-of select="#Title0">
</xsl:value-of>
</a>
</li>
<xsl:value-of select="$Footer" disable-output-escaping="yes" />
</xsl:template>

Yes, <xsl:sort/> can only be a child node of either <xsl:apply-templates> or <xsl:for-each> (and of <xsl:perform-sort> in XSLT 2.0).
Recommendation: Take at least a mini-course in XSLT and XPath so that you at least grok the fundamental concepts.
How can I create a link to the rest of the paragraph in an announcement in SharePoint, that displays the word: read more
Cheers
I've found that the cleanest, easiest way to do this is to create a template in ItemStyle.xsl which selects a substring of the body content of the announcement and displays a link below to the article itself.
After adding the following code to your ItemStyle.xsl file (in SharePoint Designer navigate to the 'Style Library/XSL Style Sheets' folder), you can modify the web part through the browser, and change the Item Style (Presentation/Styles) to 'ReadMoreAnnouncements'. This code keeps the amount of characters displayed to 190 characters (see the substring($bodyContent,1,190 function call).
<xsl:template name="removeMarkup">
<xsl:param name="string" />
<xsl:choose>
<xsl:when test="contains($string, '<')">
<xsl:variable name="nextString">
<xsl:call-template name="removeMarkup">
<xsl:with-param name="string" select="substring-after($string, '>')" />
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="concat(substring-before($string, '<'), $nextString)" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="ReadMoreAnnouncements" match="Row[#Style='ReadMoreAnnouncements']" mode="itemstyle">
<br />
<div class="RMAnnouncementsTitle">
<xsl:value-of select="#Title" />
</div>
<div class="RMAnnouncementsBody">
<xsl:variable name="bodyContent">
<xsl:call-template name="removeMarkup">
<xsl:with-param name="string" select="#Body"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="substring($bodyContent,1,190)" />
...
<br />
<a>
<xsl:attribute name="href">
/Lists/Announcements/DispForm.aspx?ID=
<xsl:value-of select="#ID">
</xsl:value-of>
</xsl:attribute>
<xsl:attribute name="class">
RMAnnouncementsMoreLink
</xsl:attribute>
read more
</a>
</div>
</xsl:template>
This should definitely work, and it's very very easy to implement.
If you have a page and can edit it in SharePoint Designer, try this.
If you want to have a web part that shows the announcement the way you want, try this.
