Xpath + repeat: noob inside

<Involvement>
  <EU-Projects>
    <EU-Project>
      <ProjectId>1</ProjectId>    
    </EU-Project>
    <EU-Project>
      <ProjectId>2</ProjectId>
    </EU-Project>
  </EU-Projects>
</Involvement>

<projects>
  <Project ProjectId="2">
    <ProjectAcronym>ALVIS</ProjectAcronym>
  </Project>
  <Project ProjectId="1">
    <ProjectAcronym>PALETTE</ProjectAcronym>
  </Project>
</projects>

1) I believe the instance must contain a single-rooted XML snippet. Yours has 2 roots.

2) instance needs to be prefixed <xforms:instance>

3) this path:

//Project[@ProjectId = //EU-Project[index('EU-Project-repeat')]/ProjectId]/ProjectAcronym

...is not going to work because the context node is:

instance('profile-instance')//EU-Projects/EU-Project

...and there are no descendants called "Project"

I re-factored your code - see attached.

It's terrible how some times the simplest things won't work...

I repeat through all EU-Project and I would like to output the name of the project instead of only the id.

I have the following :

<instance id="profile-instance">

<Involvement>
  <EU-Projects>
    <EU-Project>
      <ProjectId>1</ProjectId>&n! bsp;  nt>
    </EU-Project>
    <EU-Project>
      <ProjectId>2</ProjectId>
    </EU-Project>
  </EU-Projects>
</Involvement>

<projects>
  <Project ProjectId="2">
    <ProjectAcronym>ALVIS</ProjectAcronym>
  </Project>
  1">
    <ProjectAcronym>PALETTE</ProjectAcronym>
  </Project>
</projects>

</instance>

<xforms:group ref="instance('profile-instance')">
    <xforms:repeat id="EU-Project-repeat" nodeset="//EU-Projects/EU-Project">
        
    <xforms:output ref="//Project[@ProjectId = //EU-Project[index('EU-Project-repeat')]/ProjectId]/ProjectAcronym" />                                                     &! nbsp;

</xforms:group>


My ouput will always show the same project name, the first one, i.e. Alvis. How come ? My index is not right ?

Mmmm maybe XPath is quite powerful, but it's giving me a headache :)

Maybe complicated at first sight. There can be several projects, each projects is defined with serveral WPs. Every WPs can be then defined again with tasks (2nd part). The first part tells me what user is part of what project, and more specifically,  what tasks in what  WPs  he participates!

The following will give me for one project the list of WPs, and in it the list of all the tasks. The problem is that now I would like to recuperate the information concerning the user to see in what tasks he linked to. I showed below where I have a problem :

<xforms:group ref="instance('test')">
    <xforms:repeat id="EU-Project-repeat" nodeset="//EU-Projects/EU-Project">                       
       <h2><xforms:output ref="for $v in ProjectId return instance('test')//Project[@ProjectId = $v]/ProjectAcronym" /></h2>
       <br />
       <xforms:repeat id="WPs-repeat" nodeset="for $v in ProjectId return instance('test')//Project[@ProjectId = $v]/WPs/WP"> 
           <xforms:group appearance="xxforms:fieldset">
                <xforms:label ref="Title" />
                <xforms:select ref="." appearance="full"> <!-- Problem here -->
                    <xforms:itemset nodeset=".">
                        <xforms:label ref="Name"/>
                        <xforms:value ref="TaskNo"/>
                    </xforms:itemset>
                </xforms:select>
            </xforms:group>      
        </xforms:repeat>
    </xforms:repeat>
</xforms:group>

When I do the xforms:select, i'm in the context of Project/WPs/WP ... so I have to "get out" of it to go to Involvement/EU-Projects/EU-Project/WPs/WP/Tasks/Task. But how do I link the proper one with the actual context ? And once that is ok, I have to again reference to the proper label & value which is not in the same context of the ref just above. It's driving me nuts :). Any hints ?
