<p class="MsoNormal"><span style="color:#1F497D">The reason this is a bit more complex than just outputting the value is that the subjects can be multi-lingual, so there is a translation from the stored value to the ‘human’ version in a specific language (even
if you’re not using them!) – based on the language used for the session.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">How should $data->{B} be constructed when there are multiple subjects?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">The ‘push @dcdata’ line should be changed to do whatever you need – maybe constructing a string that is then assigned to $data->{B}.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-CA" style="font-size:12.0pt;font-family:"Sylfaen",serif">I’m wondering if someone could help me here. Using an export plugin, I would like to export a value from a subject tree.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-size:12.0pt;font-family:"Sylfaen",serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-size:12.0pt;font-family:"Sylfaen",serif">Currently, the code is:
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="FR-CA" style="font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-family:"Courier New"">$data->{B} = $dataobj->get_value( "divisions" ) if $dataobj->exists_and_set( "divisions" );<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-size:12.0pt;font-family:"Sylfaen",serif">This works, but it exports the “subject ID string” rather than the rendered subject.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-size:12.0pt;font-family:"Sylfaen",serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA" style="font-size:12.0pt;font-family:"Sylfaen",serif">How can I export the associated subject instead of the ID? Our archive is multilingual but these “subjects” are in only one language.<o:p></o:p></span></p>
