I am trying to write an XSLT to check if L24/ITEM segment is repeating or not, if its repeating then we need create separate L24 segment with one ITEM segment, remaining segments will be same. which means ITEM is the key to repeat its header node L24. my XSLT is not giving the expected results, can you please assist here.

** XSLT I used is below:**
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/EXTR001">
<xsl:copy>
<xsl:apply-templates select="EXTR001"/>
<xsl:apply-templates select="ITEM"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ITEM">
<xsl:if test="count(ITEM) >1">
<xsl:apply-templates select="ITEM"/>
</xsl:if>
</xsl:template>
<xsl:template match="ITEM">
<xsl:variable name="EXTR001" select="/EXTR001"/>
<xsl:copy-of select="$EXTR001"/>
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>
I would approach it like this, using template modes:
Have a specialized template that matches the L24 that have multiple ITEM (you could either test count(ITEM) > 1 or a simple predicate to test if there is ITEM[2]
Inside of that template that matches L24 that have multiple ITEM, apply-templates in the mode="split"
Have a template matching ITEM in mode="split that applies templates to it's parent, L24 in that mode and passes itself as a parameter to the template
In the template matching L24 in the mode="split", copy the element and apply-templates to all of it's attributes and the preceding-sibling::node() of the ITEM (excluding any other ITEM), then copy the ITEM, and finally apply-templates to it's following-sibling::node() (except for any other ITEM)
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="L24[ITEM[1]]">
<xsl:apply-templates select="ITEM" mode="split" />
</xsl:template>
<xsl:template match="ITEM" mode="split">
<xsl:apply-templates select=".." mode="split">
<xsl:with-param name="item" select="."/>
</xsl:apply-templates>
</xsl:template>
<xsl:template match="L24" mode="split">
<xsl:param name="item"/>
<xsl:copy>
<xsl:apply-templates select="@*|$item/preceding-sibling::node()[not(self::ITEM)]" />
<xsl:copy-of select="$item"/>
<xsl:apply-templates select="$item/following-sibling::node()[not(self::ITEM)]" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
