Hi All, not very clear to me - should ancestor::* return nodes in document order or
not? what is the correct output? <?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"> <xsl:output
indent="yes"/> <xsl:template
match="/"> <out> <xsl:for-each
select="//center"> <xsl:apply-templates
select="ancestor::"/> </xsl:for-each>
</out> </xsl:template> <xsl:template
match=""> <xsl:value-of
select="name(.)"/><xsl:text>
</xsl:text> </xsl:template> </xsl:stylesheet>
-------------------- <?xml version="1.0"?>
<far-north> <north> <near-north>
<far-west/> <west/> <near-west/>
<center> <near-south> <south>
<far-south/> </south> </near-south>
</center> <near-east/> <east/>
<far-east/> </near-north> </north>
</far-north> ------------------ this? <out> near-north north
far-north </out> ---------- or this? <out> far-north north
near-north </out> Thanks Stefan

Questions about the XSLT language specification are best asked on the xsl-list at
mulberrytech.com - this list is for questions on matters specific to the Saxon product.
The rules are described differently in the XSLT 1.0 and 2.0 specifications, but the
effect is the same. In 1.0, a path expression such as ancestor::* returns an unordered
set of nodes, but XSLT instructions such as xsl:apply-templates always process the nodes
in document order. In 2.0, path expressions such as ancestor::* return a sequence of
nodes in document order. Either way, your second answer is the correct one. Michael
