Subject: Re: [docbook-apps] Error processing DocBook assemblies with XProc (Calabash): "There is no Saxon extension function with the local name node-set"
Hi Graeme,The DocBook XSL stylesheets are written for XSLT 1.0, and Saxon 9 (HE or EE) is a XSLT 2.0 processor. The 1.0 DocBook stylesheets do not work reliably with Saxon 9, even with the backwards compatibility mode. All the XSLT 1.0 processors now support the EXSLT functions, so that dependency has not generally been a problem. There is a separate effort to develop DocBook stylesheets for XSLT 2.0, but I don't think it has stylesheets for assembly yet. Sorry.

Sorry folks, one more detail: I also tried the XPL workflow in both calabash-1.0.15-95 and calabash-1.0.15-94 to see if the issue was caused by the version of Saxon I'm using. I read somewhere that Saxon HE doesn't support the EXSLT extension functions, so I tried to select EE by adding the '-P he' flag. That didn't make any difference. Do the DocBook stylesheets really require the EXSLT extension functions? If so, is there a workaround to be able to use them with Saxon-HE? I don't have EE and don't have an easy way of obtaining it.

I'm processing DocBook 5.1 assembly files with the DocBook namespace stylesheets version 1.78.0. Using Saxon 8.7 and the 'assembly/assemble.xsl' stylesheet, I can turn my assemblies into 'consolidated' DocBook articles, books (or whatever). However, when I apply the same XSLT transformation using Calabash XProc, I get the following error: calabash -D --input source=file:/Users/graeme/git/ncr/documentation/projects/project.xml doc-generate.xpl Nov 20, 2013 11:42:05 AM com.xmlcalabash.util.DefaultXProcMessageListener error SEVERE: file:/Users/graeme/git/ncr/documentation/target/generated-resources/docbook/assembly/assemble.xsl:552:err:XTDE1425:Cannot find a matching 1-argument function named {http://exslt.org/common}node-set().
