[xsl] Identity Transform with special grouping

[Senthilukvelaan <skumaravelan@xxxxxxxxxxxxxx>]

Hi

I am trying to do the identity transform with grouping on the node
name under section. I want select only the first section node and put
it under sections. Based the conditions I might need to select more
than one section. The application might change the configuration to
make 2 or 3 ..n.


My XML looks like
<event>
<note>
</note>
<note>
</note>
<header>
<section>
<para1>test</para1>
<para1>test</para1>
</section>
<section>
<para1>test</para1>
<para1>test</para1>
</section>
<section>
<para1>test</para1>
<para1>test</para1>
</section>
</header>
<payload>
<elements/>
</payload>
</event>

My xslt looks for the expected out


<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:output method="xml" omit-xml-declaration="yes"  indent="yes"
encoding="UTF-8" />

<!--NO change here is expected, because node names are dynamic in nature-->
<xsl:template match="node() | @*">
<xsl:copy>
<xsl:apply-templates select="node()| @*"/>
</xsl:copy>
</xsl:template>

 <xsl:template match="header/section[position() &lt; 2]" >
     <xsl:apply-templates select="@*|node()"/>
</xsl:template>

<xsl:template match="section" >
</xsl:template>
</xsl:stylesheet>

My expected output is
<event>
<note>
</note>
<note>
</note>
<header>
<sections>
<section>
<para1>test</para1>
<para1>test</para1>
</section>
</sections>
</header>
<payload>
<elements/>
</payload>
</event>
