Hello Ragulf,
Thanks for answer.. Yes my XML is wellformed one..
I got the following output using that XSL. Here inner
level content is repeated one more time that the
problem.
<?xml version="1.0" encoding="UTF-8"?>
<X1 level="1">
<X2 level="2">
<X3 level="3"/>
<X3 level="3"/>
<X3 level="3"/>
</X2>
<X2 level="2"/>
<X2 level="2"/>
</X1>

Hi Raj,
Is it possible to arrange this XML to the
following
XML element using XSL and using level attributes.
Short answer: Yes.
I suppose that the real XML is wellformed....
<xsl:template match="/">
<!-- This solution assumes that *[(_at_)level='1'] is
the root of the document -->
<xsl:apply-templates select="*[(_at_)level='1']">
</xsl:template>
<xsl:template match="*">
<xsl:param name="current-level" select="'1'"/>
<xsl:variable name="current-id"
select="generate-id()"/>
<xsl:copy> <!-- Shallow copy of the current node
-->
<xsl:copy-of select="@*"/> <!-- Copy all the
attributes -->
<!-- Get the logical children (will be called
recursively): -->
<xsl:apply-templates
select="following-sibling::*[(_at_)level=$current-level+1][generate-id(preceding-sibling::*[(_at_)level=$current-level])=$current-id]"><xsl:with-param
name="current-level"
select="$current-level+1"/></xsl:apply-templates>
</xsl:copy>
</xsl:template>
If you change the elements name so that they are the
same (say X),
then you can use X instead of * in this solution.
This will make the
templates more specific.
This solution, I think, does not have anything that
has not been
discussed with you before in various posts.
First predicate ([...]) ensures that the element in
question will be
at a level deeper that the current one.
Second predicate ([...]) ensures that the template
will not call
children of a sibling parent.
Others on this list have suggested that you try out
some of the
tutorials that exists on the net. If you can get
hold of "XSLT,
programmers reference (2nd ed)" by Michael Kay, I
think there is an
example of this problem in that book. It is a great
book for general
understanding XSL as well as the reference that its
title says it is.

Ragulf Pickaxe :-)
