Is it possible to sort a set of elements with an unknown number of sort
keys:
<root>
<crumbtrail>
<crumb>top</crumb>
<crumb>sport</crumb>
<crumb>football</crumb>
<crumb>liverpool</crumb>
</crumbtrail>
<crumbtrail>
<crumb>top</crumb>
<crumb>sport</crumb>
</crumbtrail>
<crumbtrail>
<crumb>top</crumb>
<crumb>sport</crumb>
<crumb>cricket</crumb>
</crumbtrail>
</root>
I need to sort this in the first instance depending on the first crumb
element, then if two crumbtrails share identical values on the second crumb
element etc.etc.
The problem is There could be any number of crumb elements and I don`t want
to have to write
<xsl:sort select="crumb[1]"/>
<xsl:sort select="crumb[2]"/>
<xsl:sort select="crumb[3]"/>
<xsl:sort select="crumb[4]"/>
<xsl:sort select="crumb[5]"/>
.
.
etc.
as the sort key since there could be any number of crumb elements.
Thanks
