xslt sorting for some part of a file - sorting

Question

I'm very new to XSLT, and I want to sort a part of XML file.(keeping all the file data)
Here's the file :
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<Project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="test.xsd">

Here's my XSLT :
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns="urn:TestNamespace" >
<xsl:output indent="yes" />
<xsl:strip-space elements="*"/>
<xsl:template match="text()[not(string-length(normalize-space()))]"/>
<xsl:template match="Project">
<xsl:copy>
<xsl:apply-templates select="Target">
<xsl:sort select="TargetName"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
<!-- global template to copy everything that doesn't match the other templates -->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
I got a XML file sorted by TargetName as output, but with only Target nodes....
How can I setup the select case to keep the unfiltered nodes ?
I also tested with :
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:apply-templates select="Target">
<xsl:sort select="TargetName"/>
</xsl:apply-templates>
</xsl:copy>
In this case, all data is kept but there is no sorting ?
I will appreciate some explanation to improve my knowledge.
Best Regards

Answer 1

One approach is:
<xsl:template match="Project">
<xsl:copy>
<xsl:apply-templates select="node()">
<xsl:sort select="TargetName" />
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
Why is your solution not working:
<xsl:apply-templates select="Target">
You select only Target to apply further.

Answer 2

I would probably do this (using XSLT 2.0):
<xsl:template match="Project">
<xsl:copy>
<xsl:for-each-group select="*" group-adjacent="node-name()">
<xsl:apply-templates>
<xsl:sort select="TargetName"/>
</xsl:apply-templates>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
on the assumption that sorting groups of elements other than Target elements does no harm. But it would probably be cleaner to have a conditional (xsl:choose) inside the xsl:for-each-group so the sorting is only done when test="self::Target".
