Hello,
my requirement is to trasnform one form of XML into another form. The i/p data does not have correct levelling and looping. The levels are identified based on the attribute CLASS.
Here's my input data:
<?xml version="1.0"?>
<HTML>
<BODY LANG="EN-US" STYLE="text-justify-trim:punctuation">
<DIV CLASS="WordSection1">
<P CLASS="ahead" STYLE="margin-left:0in;text-indent:0in">A</P>
<P CLASS="ahead" STYLE="margin-left:0in;text-indent:0in"></P>
<P CLASS="Main">
<B>ABSOLUTE DEEDS AS MORTGAGES,</B> 2.01
</P>
<P CLASS="Main"></P>
<P CLASS="Main">
<B>ACCELERATION OF OBLIGATION,</B> 5.01 to5.04. (<I>See</I> <B>DEFAULT AND ACCELERATION OFOBLIGATION</B>)
</P>
<P CLASS="Main"></P>
<P CLASS="Main">
<B>AFFIDAVITS</B>
</P>
<P CLASS="Sub1">Attorneys' fees</P>
<P CLASS="Sub2">Affidavit of independent counsel in support ofaward, Form p. 503</P>
<P CLASS="Sub1">Costs, affidavit as to, Form p. 504</P>
<P CLASS="Sub1">Financial affidavit, Form p. 452</P>
<P CLASS="Sub2">Constructive service</P>
<P CLASS="Sub3">Publication, service by</P>
<P CLASS="Sub4">Affidavit demonstrating due diligence,11.08</P>
<P CLASS="Sub2">Default judgment against defendant who hasn'tanswered</P>
<P CLASS="Sub3">Non-military affidavit, 11.10, Form p.466</P>
<P CLASS="Sub1">Summary judgment motion, affidavits supporting,13.03, Form p. 484</P>
<P CLASS="Sub1"></P>
<P CLASS="Main">
<B>AFFIRMATIVE DEFENSES</B>
</P>
<P CLASS="Sub1">
Avoidances to defenses, 27. (<I>See</I><B>AVOIDANCES</B>)
</P>
<P CLASS="Sub1">
Defenses generally. (<I>See</I><B>DEFENSES</B>)
</P>
<P CLASS="Sub2">Breach of contract, statute of frauds</P>
<P CLASS="Sub3">Affirmative defenses not precluded, 29.03</P>
</DIV>
</BODY>
</HTML>
-------------------------
The corresponding sample o/p is as foollws:
<?xml version="1.0"?>

</level3>
</level2>
</level1>
</level0>
</in:body>
</em:index>

I have written an xslt for this but it not able doing the transformation correctly. Please help me with this as this is very urgent and critical.
Her's my sample XSLT:
<?xml version="1.0" encoding="utf-8"?>
