Hello Aruniima,

you have to use <xsl:copy-of select="//Header/*[name()=$Path]"/>, but with this you will create a Result Tree Fragment, which can be converted back to a node set via an extension function.

But maybe it's enough to use:

<xsl:variable name="xpath-header" select="//Header"/>

<xsl:variable name="xpath" select="$xpath-header/*[name()=$Path]"/>

and do the logic whether to use $xpath-header or $xpath later. Maybe you can also use

<xsl:variable name="xpath" select="//Header/*[name()=$Path] | //Header"/>

(UNION of both node sets) and choose later the correct node/value from this node set.

Regards,

Joerg

Hi,

How can I achieve the following of choosing a set of nodes based to
conditions....
Something like this but which allows me to have a set of nodes & not a
single value??? Kindly help as I am really stuck on this.

<xsl:param name="Path" select="'p_ptr_str_ln_txn_inq_com'"/>
<xsl:variable name="xpath">
<xsl:choose>
<xsl:when test="string-length($Path) != 0">
<xsl:value-of select="//Header/*[name()=$Path]"/>
</xsl:when>				
<xsl:otherwise>
<xsl:value-of select="//Header"/>				
</xsl:otherwise>				
</xsl:choose>			
</xsl:variable>

aruniima
