RE: [xsl] Extracting data from external file

["Joga Singh Rawat" <jrawat@xxxxxxxxxxxxxx>]

I want to read value of attribute @n and open its corresponding file. If
value of @n is equal to value of @a than extract the value of child of the
element i.e <y>. Currently the file is load twice. Can we clear that buffer
before loading to another file because it is possible that there may be
differenal external file for every elememt <b>.

By looking into the example data you provided, file_ext.xml is loaded twice.
Your current output is exactly reflect your logic in the XSLT code.

There are many ways to get your expected output but what logic are you going
to put there.
