how do I amaned an existing xemement type object in memory ?
I have something like below XElement in my memory , I want to modify the same before proceeding to next iteration in loop. Want to add to group all nodes. Using xElement.Add didnt worked - so wondering whats the best possible approach?
<Root>
<deals>
<deal>
<dealid> D1 </dealid>
<Trade> T1</Trade>
<Details> dt1 </Details>
<Details> dt2 </Details>
<Trade> T2</Trade>
<Details> dt1 </Details>
<Details> dt2 </Details>
<Group> g1 </Group>
<Group> g2 </group>
</deal>
</deals>
<Root>
This has been done by using two different XElement objects and merging both just after each iteration - thanks for lookint into this.

I'm trying to iterate through an xml file with groovy to get some values.
I found many people with the same problem, but the solution they used doesn't work for me, or it's too complicated.
I'm not a groovy dev, so I need a bullet proof solution which I can implement.
Basically I have an xml response file that looks like this: ( it looks bad but that's what I get)
<Body>
<head>
<Details>
<items>
<item>
<AttrName>City</AttrName>
<AttrValue>Rome</AttrValue>
</item>
<item>
<AttrName>Street</AttrName>
<AttrValue>Via_del_Corso</AttrValue>
</item>
<item>
<AttrName>Number</AttrName>
<AttrValue>34</AttrValue>
</item>
</items>
</Details>
</head>
</Body>
I've already tried this solution I found here on StackOverflow to print the values:
def envelope = new XmlSlurper().parseText("the xml above")
envelope.Body.head.Details.items.item.each(item -> println( "${tag.name}") item.children().each {tag -> println( " ${tag.name()}: ${tag.text()}")} }
the best I get is
ConsoleScript11$_run_closure1$_closure2#2bfec433
ConsoleScript11$_run_closure1$_closure2#70eb8de3
ConsoleScript11$_run_closure1$_closure2#7c0da10
Result: CityRomeStreetVia_del_CorsoNumber34
I can also remove everything after the first println, and anything inside it, the result is the same
My main goal here is not to print the values but to extrapolate those values from the xml and save them as string variables...
I know that using strings is not the best practice but I just need to understand now.
Your code as is had 2 flaws:
with envelope.Body you would NOT find anything
if you fix No. 1, you would run into multiple compile errors for each(item -> println( "${tag.name}"). Here the ( is used instead of { and you use an undefined tag variable here.
The working code would look like:
import groovy.xml.*
def xmlBody = new XmlSlurper().parseText '''\
<Body>
<head>
<Details>
<items>
<item>
<AttrName>City</AttrName>
<AttrValue>Rome</AttrValue>
</item>
<item>
<AttrName>Street</AttrName>
<AttrValue>Via_del_Corso</AttrValue>
</item>
<item>
<AttrName>Number</AttrName>
<AttrValue>34</AttrValue>
</item>
</items>
</Details>
</head>
</Body>'''
xmlBody.head.Details.items.item.children().each {tag ->
println( " ${tag.name()}: ${tag.text()}")
}
and print:
AttrName: City
AttrValue: Rome
AttrName: Street
AttrValue: Via_del_Corso
AttrName: Number
AttrValue: 34
I am trying to create a report in fetchxml on crm 2011 that displays a list of Account Names, and also in the same row displays the date of ONLY the most recent activity for that account.
So
Report should look like
Account1, Date of most recent activity for Account 1
Account2, Date of most recent activity for Account 2
Account3, Date of most recent activity for Account 3
I have a fetch query that pulls the correct data, but it pulls a row for each activity for the account instead of just for the newest activity.
so it looks like
Account1, Date of most recent activity for Account 1
Account1, Date of other activity for Account 1
Account2, Date of most recent activity for Account 2
Account2, Date of other activity for Account 2
Account3, Date of most recent activity for Account 3
Here is my fetch
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="true" aggregate="false">
<entity name="<accountentityname>"
<attribute name="<accountname>" />
<link-entity name="activity" from="<regardingaccoutnfield>" to="<account field>" visible="false" link-type="outer">
<attribute name="<date of activity>" />
</link-entity>
</entity>
</fetch>
Any suggestions?
Thanks.
Not sure if the maxaggregate attribute will work with datetimes, but if it does that might work
What you're wanting to do requires a subquery. This is something that CRM does not support.
If you're not using CRM Online, just perform a standard SSRS query using SQL rather then FetchXml.
If you're just trying to pull back data with the SDK, you could perform the subquery on the client side.
Why Max Aggregate Won't Work
If your column you were wanting to get the max value on was a number you could use an aggregate, but Aggregate functions AVG, MIN, MAX, or SUM can only be applied to attributes of type integer, float, money, bigint, or decimal.
That's the error if you attempt to run this query:
var xml = #"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='true' aggregate='true'>
<entity name='contact'>
<attribute name='fullname' alias='name' groupby='true' />
<attribute name='contactid' alias='id' groupby='true' />
<link-entity name='activitypointer' from='regardingobjectid' to='contactid' alias='ad' link-type='outer'>
<attribute name='createdon' alias='createdon_max' aggregate='max' />
<filter type='and'>
<condition attribute='createdon' operator='not-null' />
</filter>
</link-entity>
</entity>
</fetch>";
EntityCollection fetchResult = service.RetrieveMultiple(new FetchExpression(xml);
You can do a sort on the date and return the first record only!
Do your query on accounts then return a for each & use something like:
<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
<entity name="activitypointer">
<attribute name="scheduledstart" />
<order attribute="scheduledstart" descending="true" />
<filter type="and">
<condition attribute="scheduledstart" operator="not-null" />
</filter>
</entity>
</fetch>
OR similar Query Expression:
QueryExpression query = new QueryExpression("activitypointer");
query.ColumnSet.AddColumns("scheduledstart");
query.AddOrder("scheduledstart", OrderType.Descending);
EntityCollection results = service.RetrieveMultiple(query);
Then something like:
(DateTime)(((Entity)results.Entities.First()).Attributes["scheduledstart"]);
Add the condition that the regarding field is equal to the account.id that's in scope for the for each loop
<Shape ID="1" NameU="Start/End" Name="Start/End" Type="Shape" Master="2">
....</Shape>
<Shape ID="2" NameU="Start/End" Name="Start/End" Type="Shape" Master="5">
....</Shape>
I have to return the Master value for every ID value.
How can i achieve it by using LINQ to XMl.
You didn't really present how your XML document looks like, so I assumed it's as follow:
<Shapes>
<Shape ID="1" NameU="Start/End" Name="Start/End" Type="Shape" Master="2">
</Shape>
<Shape ID="2" NameU="Start/End" Name="Start/End" Type="Shape" Master="5">
</Shape>
</Shapes>
You can simply get Master attribute value for all different ID like that:
var xDoc = XDocument.Load("Input.xml");
var masters = xDoc.Root
.Elements("Shape")
.ToDictionary(
x => (int)x.Attribute("ID"),
x => (int)x.Attribute("Master")
);
masters will be Dictionary<int, int> where key is your ID and value is corresponding Master attribute value.
I have the following FXML:
<ChoiceBox>
<items>
<FXCollections fx:factory="observableArrayList">
<String fx:value="2 minutes" />
<String fx:value="5 minutes" />
<String fx:value="15 minutes" />
</FXCollections>
</items>
</ChoiceBox>
But in the GUI it just shows a ChoiceBox with a default of nothing. I would like the first element in the list to be the default, and for a choice of "null" or nothing to be prohibited.
How do I accomplish this?
I added the value attribute to the ChoiceBox tag, and that worked.
<ChoiceBox value="2 minutes">
<items>
<FXCollections fx:factory="observableArrayList">
<String fx:value="2 minutes" />
<String fx:value="5 minutes" />
<String fx:value="15 minutes" />
</FXCollections>
</items>
</ChoiceBox>
First, you should import your needed value model, like Crowell answer, you should import like this in your fxml header:
<?import javafx.collections.*?>
Second, if you want's import your own model, import it first and then like this:
<?import com.zzg.mybatis.generator.model.*?>
....
<ChoiceBox layoutX="24.0" layoutY="14.0" prefWidth="150.0">
<items>
<FXCollections fx:factory="observableArrayList">
<DatabaseDTO name="MySQL" value="1"></DatabaseDTO>
<DatabaseDTO name="Oracle" value="2"></DatabaseDTO>
</FXCollections>
</items>
</ChoiceBox>
#Groostav: In case we programmatically "know" the value that should appear as selected (for example, we landed in an edit form), we can do the following:
1) Add a new item with index 0 (that is, the element we need to show as selected):
myChoiceBox.getItems().add(0, ItemObtainedProgrammatically);
2) Show the item as selected (since we already know it's at position 0):
myChoiceBox.getSelectionModel().select(0);
Probably this qualifies as a dirty hack, but it works. The con: You have the same item twice in your choicebox
I have a numer, "n" in a property in MSBuild. I also have a string "Str" that needs to be duplicated n-times to achieve a final string that is the repetition of "Str" n times.
Eg. If n is 3 and Str is "abc", what I want to obtain is "abcabcabc"
Since one cannot loop in MSBuild, I don't know how to achieve this. Perhaps with an item group, but how do I create one based on a property containing an "n" count?
Thanks!
To create a String repeated n times, you can also do this (at least in MSBuild Tools v4.0):
<SomeRepeatedString>$([System.String]::New("-", 40))</SomeRepeatedString>
usually for things like this I resolve to using inline C#, as it costs me less time than searching all over the internet to find a 'true' msbuild solution; here you go:
<?xml version="1.0" encoding="utf-8"?>

<MyString>abc</MyString>
