I agree with your point that using it node-name() instead of name() would be more "correct", but knowing that many people come from XSLT 1.0 where they are used to using name(), I don't really see the difference (even though one might argue that a string is compared differently than a QName). One special situation occur, perhaps, where the source document has different redefining namespaces with the same prefix (or different null namespaces). In that case and in the rare event that the node names match, the node-name() function will result in unequal and the name() function will result in equal: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:output method="text" /> <xsl:variable name="testset"> <date xmlns="http://foo" /> <date xmlns="http://bar" /> </xsl:variable> <xsl:template match="/" name="start"> <xsl:value-of select=" 'node-name comparison:', node-name($testset/*[1]) eq node-name($testset/*[2])" /> <xsl:text>
</xsl:text> <xsl:value-of select=" 'name comparison:', name($testset/*[1]) eq name($testset/*[2])" /> </xsl:template> </xsl:stylesheet> Will output the following: node-name comparison: false name comparison: true So, all in all and in the end, to prevent hard to find errors, I tend to agree with your advice and adopt it as a "best practice".
