Hi..
Thanks a lot David, for the quick reply and putting up
with the inconsistencies in the code that i sent..
Taking your explaination I have solved the problem by
saying..
<xsl:value-of
select="ResourceTypeSet/Type[number($Index)]"/>
instead of
<xsl:value-of select="ResourceTypeSet/Type[$Index]"/>
The purpose is solved but i want to know if it is the
right thing to do....
Also i have a very long standing problem with
specifying dynamic xpaths...
Suppose my xml is
<a>
<b>
<c>try</c>
</b>
</a>
and my xsl is something like...
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:variable name="path">c</xsl:variable>
<!-- Now i am trying to access the dynamic path a/b/c
-->
<xsl:value-of select="/a/b/$path"/>
<!-- The error shown is Nodetest expected..-->
<!-- Next i try concatenating the values in a variable
-->
<xsl:variable name="fullpath"
select="concat('/a/b/',$path)"/>
<!-- and then try to access the value for this path
-->
<xsl:value-of select="$fullpath"/>
<!-- Here the xpath /a/b/c is displayed. So how do i
use the variable path to actually get the value for
that path which happens to be "try" in this case-->
</xsl:template>
</xsl:stylesheet>

You don't need recursion to do that
<xsl:copy-of select="Type/text()"/>
is all you need.
However
<xsl:value-of select ="ResourceTypeSet/Type[$In]"/>
I assume thst isn't your actual code as $In is not
defined, assuming
that you have
<xsl:value-of select
="ResourceTypeSet/Type[$Index]"/>
then your problem is that the short hand Type[3] for
Type[position()=3]
only tales place if the thing in teh [] is a number.
$Index starts off as a number
<xsl:with-param name="Index" select="1"/>
but then you redeclare it to be a result tree
fragment
<xsl:with-param name="Index"><xsl:value-of
select="$Index+1"/></xsl:with-param>
If you use a result tree fragment as a boolean then
it is always true as
it corresponds to a non empty node set so
ResourceTypeSet/Type[$Index]
is
ResourceTypeSet/Type[true()]
which is
ResourceTypeSet/Type
ie it selects all the Tyope nodes, then
<xsl:value-of
always returns the value of (only) the first node
selected, so you will
always get the first one back.
