Re: generic sort based on attribute names

Suppose
<root>
 <e b="bb" y="yy"/>
 <e z="zz" a="aa"/>
</root>
is the XML I want to sort.
The result of the sort should be
<root>
  <e a="aa" z="zz" />
  <e b="bb" y="yy" />
</root>
Thus the attributes within an element are sorted and then the key used
for sorting elements would be:
'az' and 'by' respectively (thus 'az' < 'by').

<xsl:template match="root">
	<xsl:variable name="sortkey">
		<xsl:apply-templates select="e" mode="sortkey"/>
	</xsl:variable>
	<xsl:copy>
		<xsl:apply-templates select="e" >
			<xsl:sort select="substring($sortkey,position()*2 - 1, 2)"/>
		</xsl:apply-templates>
	</xsl:copy>
</xsl:template>

<xsl:template match="e" mode="sortkey">
	<xsl:apply-templates select="@*" mode="sortkey">
		<xsl:sort select="." data-type="string"/>
	</xsl:apply-templates>
</xsl:template>

<xsl:template match="@*" mode="sortkey">
	<xsl:value-of select="local-name()"/>
</xsl:template>

<xsl:template match="e">
	<xsl:copy>
		<xsl:apply-templates select="@*" >
			<xsl:sort select="." data-type="string"/>
		</xsl:apply-templates>
	</xsl:copy>
</xsl:template>

<xsl:template match="@*">
	<xsl:copy-of select="."/>
</xsl:template>
