Thank you for your advice about the result tree fragments. I found that feature very useful.
What is xx:node-set() ? Is it something portable?
It's an extension function that's available in nearly every XSLT
processor, though the namespace varies which makes it non-portable.
Several processors support the EXSLT namespace (see www.exslt.org) which
improves the situation.
I did it _without_ that function, as follows (comments welcome).
<xsl:variable name="allphotos"> <xsl:apply-templates select="/fotos/foto" mode="identity"> <xsl:sort order="ascending" select="@id" data-type="number" /> </xsl:apply-templates> <foto id="100000000000" dummy="logo" src="logo.gif" href="http://homepage" /> <foto id="100000000001" dummy="yes" /> <foto id="100000000002" dummy="yes" /> <foto id="100000000003" dummy="yes" /> <foto id="100000000004" dummy="yes" /> <foto id="100000000005" dummy="yes" /> <foto id="100000000006" dummy="yes" /> <foto id="100000000007" dummy="yes" /> </xsl:variable>
<xsl:for-each select="$allphotos/foto[(position() mod 8) = 1 and not(@dummy='yes')]">
Then you're using a processor that implements the "implicit conversion of result tree fragments to node-sets" offered by the XSLT 1.1 and XSLT 2.0 working drafts: this code isn't legal in XSLT 1.0. Which processor, might I ask?
(Saxon allows this, provided your stylesheet specifies version="1.1" or
later. But some earlier versions of Saxon allowed it regardless).
