I have specific business requirement where I need to transform the source tree bottom up. The reason being certain attribute of the parent node gets its value from a similarly caluclated child node. i.e I need to calculate a derived attribute of a child node before I can calculate the parent node's attribtue. Is this the sort of thing you mean? Note that this is an XSLT2 transform: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:output indent="yes"/> <xsl:template match="node()"> <xsl:variable name="children" as="node()*"> <xsl:apply-templates/> </xsl:variable> <xsl:copy> <xsl:sequence select="@*"/> <xsl:sequence select="($children/@a)[1]"/> <xsl:sequence select="$children"/> </xsl:copy> </xsl:template> </xsl:stylesheet> with input <?xml version="1.0" encoding="UTF-8"?>
<x>
<y>
<z a="1" b="1"/>
</y>
<y>
<z a="2" c="2"/>
</y>
</x>gives output <?xml version="1.0" encoding="UTF-8"?>
<x a="1">
<y a="1">
<z a="1" b="1"/>
</y>
<y a="2">
<z a="2" c="2"/>
</y>
