Subject: Re: [xsl] Saxon versus Xalan implementations of evaluate() extension function? From: Arian Hojat <arianhojat2000@xxxxxxxxx> Date: Wed, 6 Jul 2005 21:50:17 -0700 (PDT) |
I think just doing all evaluations in a variable beforehand should give you a bit more safety to work in saxon/xalan/both. I was using xalan with the dyn EXSLT extension and saxon and it seemed to work... Although when I wanted to make it processor independant to check beforehand what evaluate to use like so... <xsl:apply-templates use-when="function-available(dyn:evaluate)" select="dyn:evaluate($evalThis)"/>, xalan 1.0 processor seemed to have a problem with the use-when if this is an issue to work in both. I wasnt sure of a workaround). but back to the problem, does this work?... <xsl:variable name="evalThis" select="concat( '$data/', @xpathValue )" /> ... saxon:evaluate( $evalThis ) at worst try this... <xsl:variable name="evalThis" select="concat( $data, '/', @xpathValue )" /> ... saxon:evaluate( $evalThis ) Arian. --- Andrzej Taramina <andrzej@xxxxxxxxxxx> wrote: > I'm trying to get a large application to run using > Saxon 8.4 rather than Xalan, which it > uses currently, since a large chunk of cpu is being > burned in the xsl transform step. > Figured Saxon is usually a lot more efficient than > Xalan in that regard. > > But there seems to be a difference in the > functionality of xalan:evaluate versus > saxon:evaluate. > > For example: > > xalan:evaluate( concat( '$', @varname ) ) > > works fine.
