Does someone know what an XSLT 1.0 processor is expected to do if the immediate child-node of an xsl:for-each is a whitespace-only text node, which is preserved by xml:space? Section 8 clearly states that the content is xsl:sort followed by the template: <!-- Category: instruction --> <xsl:for-each select = node-set-expression> <!-- Content: (xsl:sort*, template) --> </xsl:for-each> Should any text-node, regardless if it's whitespace-only or not, be reported as invalid at such a position? Yes, it is an error, and Saxon reports it as an error, because the xml:space="preserve" creates a node of the template before the xsl:sort instruction, which is not allowed. Using the MSXML .NET Processor, I get the following result: I would assess that as a bug ... the space character is clearly part of the template and the standard does not allow any part of the template before xsl:sort. then an error is reported concerning the invalid position of xsl:sort inside xsl:for-each. I'm confused here. I think you are confused because of the bug. I believe Saxon implements this correctly. Was this maybe clarified in the XSLT 2.0 spec? Not applicable. XSLT 1 is, I belive, quite clear. Using xml:space="preserve" in a stylesheet is a syntactic mechanism to keep from having to use <xsl:text> for white-space-only nodes ... I use it for that myself. By using it you have, in effect, wrapped the first white-space-only text node in <xsl:text>, which also would not be allowed to be before <xsl:sort/>. I hope this helps. . . . . . . . .
