jstl xsl problem
[nobr]i have a xml structure that is designed according to the hr-xml standard
the xml file has a number of education historys - schools/organisations
and a number of achievements - courses
from the code below the education is selected fine, but i want to select the achivements whoch have been done at the specific school/organisation, but i dont know how to compare the schools
<x:forEach select="$resume//EducationHistory">
<tr>
<td>
<x:out select="SchoolOrInstitution/SchoolName"/>
<dl>
<dt>
Address:
<dd>
<br>
<x:out select="SchoolOrInstitution/PostalAddress/DeliveryAddress/BuildingNumber"/>
<br>
<x:out select="SchoolOrInstitution/PostalAddress/DeliveryAddress/StreetName"/>
<br>
<x:out select="SchoolOrInstitution/PostalAddress/Region"/>
<br>
<x:out select="SchoolOrInstitution/PostalAddress/Municipality"/>
<br>
<x:out select="SchoolOrInstitution/PostalAddress/PostalCode"/>
</dd>
</dt>
</dl>
</td>
<td>
<x:forEach select="$resume//Achievements">
<x:if select Achievement/IssuingAuthority =
</td>
<td>
</td>
<td>
<x:out select="SchoolOrInstitution/Degree/DatesOfAttendance/StartDate/AnyDate"/> -
<x:out select="SchoolOrInstitution/Degree/DatesOfAttendance/EndDate/AnyDate"/>
</td>
</tr>
</x:forEach>
the achievements xml looks like this:
- <Achievements>
- <Achievement>
<Description>English C</Description>
<IssuingAuthority>Grammer School</IssuingAuthority>
</Achievement>
</Achievements>
education xml looks like this:
<EducationHistory>
- <SchoolOrInstitution>
<SchoolName>Grammer School</SchoolName>
- <Degree>
- <DatesOfAttendance>
- <StartDate>
<AnyDate>2020-06-04</AnyDate>
</StartDate>
- <EndDate>
<AnyDate>2023-08-04</AnyDate>
</EndDate>
</DatesOfAttendance>
</Degree>
- <PostalAddress>
<PostalCode>Uk1903</PostalCode>
<Region>Town</Region>
<Municipality>County</Municipality>
- <DeliveryAddress>
<StreetName>Road</StreetName>
<BuildingNumber>12</BuildingNumber>
</DeliveryAddress>
</PostalAddress>
</SchoolOrInstitution>
</EducationHistory>

According to the documentation, the x:forEach tag "Evaluates the given XPath expression and repeats its nested body content over the
result, setting the context node to each element in the iteration."
This means that while you're in the one forEach loop, the context is set to the current record. You're using that to good effect with the <x:out> tags.
Now you want to iterate through an unrelated xml file? Or is it part of the same one? You're trying to access it via $resume, which is confusing me a little.
A nested forEach loop even on a completely different xml file is still assuming the context of the parent loop. Which is probably causing you a problem.
Hope this explanation helps some,

Evnafets,
I thought the same too that if an x:forEach is nested inside another x:forEach and if each x:forEach is iterating over XML files stored in a two separate XML source files.
But the Jakarta Taglibs group members claim that it is supposed to work according to this bug report here:
http://issues.apache.org/bugzilla/show_bug.cgi?id=41481
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Anyway, if you are unable to make it work inside the JSP , try to do the exact same transformation in an XSLT file and then call
<x:transform inside the JSP
Here's a nice article on how to merget 2 XML files into one:
http://www.xml.com/pub/a/2002/03/06/xslt.html , if you want to take that appropach.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I tried a simpler example of your case with the following code and as I expected , the inner loop did not work, only the outer one worked.

<x:forEach select="$parsedAuthors/authors/author">

</x:forEach>
</x:forEach>

In the above sample only the isbn was printing , but the author id from the 2nd XML file wasn't printing at all.[/nobr]
