 I have a problem regarding xsl:sort. Using an XML element like this. <Bibitem Type="Book" Label="TEI"> <Editor> <Given>C.M.</Given> <Family>Sperberg-McQueen</Family> </Editor> <Editor> <Given>L.</Given> <Family>Burnard</Family> </Editor> <Title>TEI P4: Guidelines for Electronic Text Encoding and Interchange</Title> <Address>XML Version: Oxford, Providence, Charlottesville, Bergen</Address> <Year>2002</Year> </Bibitem> it is no problem to sort the Bibitems according their Author or Editor elements with this stylesheet template: ... <xsl:if test="Bibitem/@Type='Book'"> <xsl:for-each select="Bibitem[@Type='Book']"> <xsl:sort select="Author[1]/Family | Editor[1]/Family | Organization"/> <p> <xsl:apply-templates select="."/> </p> </xsl:for-each> </xsl:if> ... Note that all three elements are allowed as 'author' of a Bibitem: Author, Editor and Organization. The problem is that if I use a Bibitem with both an Author or Editor element and an Organization element as well (which is also allowed according to the DTD), the xsl:sort breaks ("a sequence of more than one item is not allowed here" - of course). XSLT processor is Saxon 7.5.1 <Bibitem Type="Book" Label="TEI"> <Editor> <Given>C.M.</Given> <Family>Sperberg-McQueen</Family> </Editor> <Editor> <Given>L.</Given> <Family>Burnard</Family> </Editor> <Title>TEI P4: Guidelines for Electronic Text Encoding and Interchange</Title> <Organization>Text Encoding Initiative Consortium</Organization> <Address>XML Version: Oxford, Providence, Charlottesville, Bergen</Address> <Year>2002</Year> </Bibitem> I tried to use xsl:sort as child element of xsl:choose/xsl:when, but it's not allowed. What I need is to check that the xsl:sort is only used on the first child element of Bibitem - regardless if it is Author, Editor or Organization. I tried the following without any success <xsl:sort select="child::Author[1]/Family[position()=1] | child::Editor[1]/Family[position()=1] | child::Organization[position()=1]"/> I know there were a lot of questions about getting the first child element, but I found none regarding xsl:sort. I had a look at Dave Pawson's FAQ too. Any help would be appreciated. Kind regards, Maik Stührenberg XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
