note 63666 deleted from ref.xslt by sobak

Note Submitter: bat at flurf dot net ---- maurits says that libxslt should be preferred over Sablotron, but I disagree. libxslt only implements a fraction of the capabilities of Sablotron; in particular, this doesn't work in libxslt: <xsl:variable name="x"> <a>One</a> <a>Two</a> <a>Three</a> </xsl:variable> <xsl:for-each select="$x/a"> <xsl:value-of select="."/> </xsl:for-each> In Sablotron, which implements XSLT 1.1, this works fine. In libxslt's version, XSLT 1.0, a variable is a "result tree fragment", not a nodeset, and you are arbitrarily not allowed to do as much with it. Further, Sablotron allows callbacks via the document() function (see information on xslt_set_scheme_handler()) and appears to give /slightly/ more informative error messages -- they identify the line number in the XSLT file at least. In general, I can't recommend libxslt, which appears very underpowered. Sablotron is considerably more impressive.
