Hello,

I am trying to solve following problem:

Today I use identity transform. to filter elements from my original XML file and create XML output file.
I have created two XSLTs (base.xslt and filter.xslt), where base.xslt does the identity transformation and filter.xslt defines filtering rules and templates.

What I basically want is to filter elements of type "sub" and sort them under one parent node and make selections of type "main" and sort them under another parent node. One parent node for each category. (see in Filtered XML how output shoul look like).

My input XML looks like:

[Original XML]

<Documents>
   <Document chapter="1" title="title 1" href="file1.xml">
         <Article title="1.1" info="sub"/>
         <Article title="1.2" info="main"/>
    </Document>
   <Document chapter="2" title="title 2" href="file2.xml">
         <Article title="2.1" info="sub"/>
         <Article title="2.2" info="main"/>
    </Document>
</Documents>

[Filtered XML SHOULD LOOK LIKE]

<Documents>
   <Document name="main">
         <Article title="1.2" info="main"/>
         <Article title="2.2" info="main"/>
    </Document>
   <Document name="sub">
         <Article title="1.1" info="sub"/>
         <Article title="2.1" info="sub"/>
    </Document>
</Documents>
