Keep main element after sorting with xsl - xslt

Question

I have a source xml:
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<SHPMNT05>
<IDOC BEGIN="1">
<EDI_DC40 SEGMENT="1">
<TABNAM>EDI_DC40</TABNAM>
</EDI_DC40>
<E1EDT20 SEGMENT="1">
<TKNUM>0000046741</TKNUM>
<E1EDL20 SEGMENT="1">
<VBELN>1</VBELN>
<VKORG>0200</VKORG>
</E1EDL20>
<E1EDL20 SEGMENT="1">
<VBELN>1</VBELN>
<VKORG>0100</VKORG>
</E1EDL20>
</E1EDT20>
</IDOC>
</SHPMNT05>
</ns0:Message1>
</ns0:Messages>
I'm sorting all E1EDL20 elements with xslt:
<xsl:template match="E1EDT20">
<xsl:for-each select="*[not(self::E1EDL20)]">
<xsl:copy-of select="."/>
</xsl:for-each>
<xsl:for-each select="E1EDL20">
<xsl:sort select="VKORG"/>
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:template>
<!-- Default Template -->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
But in my result I'm missing the parent E1EDT20 element:
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
<ns0:Message1>
<SHPMNT05>
<IDOC BEGIN="1">
<EDI_DC40 SEGMENT="1">
<TABNAM>EDI_DC40</TABNAM>
</EDI_DC40>
<TKNUM>0000046741</TKNUM>
<E1EDL20 SEGMENT="1">
<VBELN>1</VBELN>
<VKORG>0100</VKORG>
</E1EDL20>
<E1EDL20 SEGMENT="1">
<VBELN>1</VBELN>
<VKORG>0200</VKORG>
</E1EDL20>
</IDOC>
</SHPMNT05>
</ns0:Message1>
</ns0:Messages>
What do I need to put after
<xsl:template match="E1EDT20">
to keep the element / tag in the output?
Very sorry to bother you with this beginners question but every so often I have to use xslt and I can't find the answer after search for quite some time...

Answer 1

In your template which matches E1EDT20 you don't copy the element; you only copy its children.
You should copy the element with xsl:copy, and within that, copy its attributes, and then process the child elements:
<xsl:template match="E1EDT20">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:for-each select="*[not(self::E1EDL20)]">
<xsl:copy-of select="."/>
</xsl:for-each>
<xsl:for-each select="E1EDL20">
<xsl:sort select="VKORG"/>
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:copy>
</xsl:template>

Answer 2

Wrap the content of your template in an xsl:copy instruction. You can also shorten it to:
<xsl:template match="E1EDT20">
<xsl:copy>
<xsl:copy-of select="#* | *[not(self::E1EDL20)]"/>
<xsl:for-each select="E1EDL20">
<xsl:sort select="VKORG"/>
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:copy>
</xsl:template>
