XSLT 1 (unlike XSLT2) does not have parentless elements, so it's not possible to answer the question in the subject line (or at least both "yes" and "no" are correct answers:-) > It seems to be because the elements copied to "baz-rtf" don't have a > common parent element, they aren't siblings in Xalan... That would be a bug in xalan then I think. Of course exslt:node-set is specified by EXSLt ratherthan by the XSLT spec, but it is specified as returning a standard Xpath 1 node set rather than an obect in a private data type. > It seems to be because the elements copied to "baz-rtf" don't have a > common parent element, They should have a common parent. It's easier to diescus in xslt2 where there are words for this in xslt2 <xsl:variable name="baz-rtf"> <xsl:copy-of select="//baz"/> </xsl:variable> makes a temprary tree with a document node (/) with 4 child nodes (which doesn't correspond to a well formed document but has always been allowed in xpath 1 and 2) These nodes are siblings. <xsl:variable name="baz-rtf" as="element()*> <xsl:copy-of select="//baz"/> </xsl:variable> this makes a sequence of 5 parentless eleemnt nodes, which don't have a parentt and so are not siblings. <xsl:variable name="baz-rtf" as="element()*> <xsl:sequence select="//baz"/> </xsl:variable> this makes a sequence of 5 element nodes with parent the <foo> element in the stylesheet (which is not in the variable) here the elements are siblings.
