Is there a way to append a literal string to whatever an XPath expression gets you?
e.g. from following XML:
<root>
<select>I am</select>
</root>
I would like to produce:
I am a literal
purely with XPath. What do I add to /root/select to get what I want? Important: XPath 1.0 solution required! I'm not using XSLT.
Any reason you can't simply concat() 'a literal' to the end?
Something like: concat( string(/some/selector) , ' some literal' )?

i tried this but doesn't work
print (log.split("ecsdcsdcsdfvdfv",1)[1])
You can try this
log.split('":"')[1].split('","')[0]
But this is not the best way to do what you are trying to achieve. Better parse it and get what you want.
This yield the expected result.
The way you used .split() was wrong, you did not include the " character.
string = 'ecsdcsdcsdfvdfv":"https://scdsscdcsdent-mxp1-1.cdninstdscsdcagdssdcsdam.com/v/t51.283485-19/s320x320/79000872_1455436197941341_7513464347075543040_n.pnk?_nc_ht=scontent-mxp1-1.cdninadcdcdm.codcsdcm&_nc_ohc=0fehqjedb48AX8r72Hi&oh=eb1f6a78a2dcd67e443aa7f74eee91b4&oe=5E7F0A0C","vsvdfvsfvcfvfdcvfd'
substring = string.split('ecsdcsdcsdfvdfv":"')[1].split('","vsvdfvsfvcfvfdcvfd')[0]
If you want to get the string between the ":" and ",", then you can use regular expression to do it.
re.match('(.*\":\")([^\",\"]*)(\",\".*)', log).group(2)
Given your input
'ecsdcsdcsdfvdfv":"https://scdsscdcsdent-mxp1-1.cdninstdscsdcagdssdcsdam.com/v/t51.283485-19/s320x320/79000872_1455436197941341_7513464347075543040_n.pnk?_nc_ht=scontent-mxp1-1.cdninadcdcdm.codcsdcm&_nc_ohc=0fehqjedb48AX8r72Hi&oh=eb1f6a78a2dcd67e443aa7f74eee91b4&oe=5E7F0A0C","vsvdfvsfvcfvfdcvfd'
you will get
'https://scdsscdcsdent-mxp1-1.cdninstdscsdcagdssdcsdam.com/v/t51.283485-19/s320x320/79000872_1455436197941341_7513464347075543040_n.pnk?_nc_ht=scontent-mxp1-1.cdninadcdcdm.codcsdcm&_nc_ohc=0fehqjedb48AX8r72Hi&oh=eb1f6a78a2dcd67e443aa7f74eee91b4&oe=5E7F0A0C'
And if you input something like

I'm trying to split a string (separated with the HTML break tag), without deleting the break tag. I think it's pretty messy to add a break as string after splitting, so is there any function/possibility to keep the separator while "splitting"?
Example:
<HTML><BODY><p>some text<br/>some more text</p></BODY></HTML>
Expected result:
<HTML><BODY><p>some text<br/>
some more text</p></BODY></HTML>
As far as I know SPLIT removes the separator from the results and it doesn't seem like you can change that.
But you could create your own separator by first replacing your <br/> tag with <br/> plus an arbitrary string that is highly unlikely to ever appear in your HTML source, and then split the HTML using this arbitrary string as a separator instead.
types:
begin of t_result,
segment(2000) type c,
end of t_result.
DATA:
source type string,
separator type string,
brtag type string,
repl type string,
result_tab type standard table of t_result,
result_row TYPE t_result.
brtag = '<br/>'.
separator = '|***SEP***|'.
concatenate brtag separator into repl.
source = '<HTML><BODY><p>some text<br/>some more text</p></BODY></HTML>'.
replace all occurrences of brtag in source with repl.
split source at separator into table result_tab.
LOOP AT result_tab INTO result_row.
WRITE:
result_row-segment.
ENDLOOP.
Output of that example report:
<HTML><BODY><p>some text<br/>
some more text</p></BODY></HTML>
The caveat of this solution is that your custom separator, if not chosen with some care, might appear in your HTML source on its own. I therefore would choose an arbitrary string with a special character or two that would be encoded in HTML (like umlauts) and therefore not appear in your source.
Just use the replace command. replace <br/> with <br/>CR_LF
The CR_LF refers to the carriage return linefeed character.
In more complex cases you can use regex expressions in abap.

replace all occurrences of '<br/>' in my_string with my_break in character mode.

I'm trying to read a string in a specific format
RealSociedad
this is one example of string and what I want to extract is the name of the team.
I've tried something like this,
houseteam = sscanf(str, '%s');
but it does not work, why?
You can use regexprep like you did in your post above to do this for you. Even though your post says to use sscanf and from the comments in your post, you'd like to see this done using regexprep. You would have to do this using two nested regexprep calls, and you can retrieve the team name (i.e. RealSociedad) like so, given that str is in the format that you have provided:
str = 'RealSociedad';
houseteam = regexprep(regexprep(str, '^<a(.*)">', ''), '</a>$', '')
This looks very intimidating, but let's break this up. First, look at this statement:
regexprep(str, '^<a(.*)">', '')
How regexprep works is you specify the string you want to analyze, the pattern you are searching for, then what you want to replace this pattern with. The pattern we are looking for is:
^<a(.*)">
This says you are looking for patterns where the beginning of the string starts with a a<. After this, the (.*)"> is performing a greedy evaluation. This is saying that we want to find the longest sequence of characters until we reach the characters of ">. As such, what the regular expression will match is the following string:
<ahref="/teams/spain/real-sociedad-de-futbol/2028/">
We then replace this with a blank string. As such, the output of the first regexprep call will be this:
RealSociedad</a>
We want to get rid of the </a> string, and so we would make another regexprep call where we look for the </a> at the end of the string, then replace this with the blank string yet again. The pattern you are looking for is thus:
</a>$
The dollar sign ($) symbolizes that this pattern should appear at the end of the string. If we find such a pattern, we will replace it with the blank string. Therefore, what we get in the end is:
RealSociedad
Found a solution. So, %s stops when it finds a space.
str = regexprep(str, '<', ' <');
str = regexprep(str, '>', '> ');
houseteam = sscanf(str, '%*s %s %*s');
This will create a space between my desired string.
How would I extract in Lua a text between a pattern. For example
s="this is a test string. <!2014-05-03 23:12:08!> something more"
I would need only the date/time as result: 2014-05-03 23:12:08
print(string.gsub(s, "%<!.-%!>")) doesn't work
I would need all the text WITHOUT the date/time like: "this is a
test string. something more"
The pattern "<!.-!>" works, but you need to use string.match to get the date/time part:
print(string.match(s, "<!(.-)!>"))
Note that you don't need to escape ! or < in a pattern. Of course escaping them is not an error.
To get the string without the date/time part, replace it with an empty string:
local result = string.gsub(s, "<!.-!>", "")
print(result)
You can also expand the pattern .- to validate the format of date/time more:
result = string.gsub(s, "<!%d%d%d%d%-%d%d%-%d%d%s+%d%d:%d%d:%d%d!>", "")
I Have some text file. theses texts contain a string like this(a part of text):
<abbr class="word p1"">dd</abbr>
<img src"D:\Images\1.png">
<abbr class="word p1">dd</abbr>
<img src"D:\ticket\t\1.png">
In each text file,(D:\Images\1.png) png name is different but it is always numbers(from 1 to 114)for example(1,2,3,10,...)
I want to replace this text D:\Images\[number].png with a specific text for expample:
string newtext=Replace("D:\Images\[number].png","Something");
How can i do this?
thanks.
Use a regular expression:
string newtext = Regex.Replace(text, #"(D:\\Images\\)\d+(.png)","$1Something$2");
It will replace the full match, including D:\Images\ and .png, so $1 and $2 puts back what's caught by the parentheses, so that Somthing only replaces the digits.
Use regular expressions that are represented mostly be the Regex class. See these links:
