Re: [xsl] WorldML Filteration

Joga,
Try this - it much more fun with groups and functions and it does work
for the sample provided:
Terry<?xml version="1.0" encoding="UTF-8"?>

Subject: [xsl] WorldML Filteration

Hi,
I have got a good clue about formatting elements for worldML. In the similar
effort we need to filter these elements. Comparison of "current output" and
"desired output" is sufficient to understand the requirement.

Input
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t>Azienda</w:t></w:r>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t> </w:t></w:r>
<w:r><w:rPr><w:i/><w:b/><w:i-cs/></w:rPr><w:t>Ospedaliera</w:t></w:r>
<w:r><w:rPr><w:i/><w:b/><w:i-cs/></w:rPr><w:t>, </w:t></w:r>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t>Ospedali</w:t></w:r>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t> </w:t></w:r>
<w:proofErr
w:type="spellStart"/>
<w:r><w:rPr><w:i/><w:i-cs/></w:rPr><w:t>Riuniti</w:t></w:r>
