Hi there, I'm having a problem with Xalan in cocoon-2.1 in which I process an attribute containing whitespace separated manuscript sigla (IDREFS) and then make a drop down list based using corresponding text in another file.
The file(s) in question will look something like: <ant id="c666"> <aBody wit="Foo Blort-A Blort-B"> some other stuff </aBody> </ant> The mss.xml file contains some elements like: <witness sigil="Foo" shortname="A FOO Manuscript"> descriptive text</witness> <witness sigil="Blort-A" shortname="Blort in Version A"> descriptive text</witness> <witness sigil="Blort-B" shortname="Blort in Version B"> descriptive text</witness> The XSLT as it stands works fine: It goes, and makes (manually) a tokenized list of the whitespace separated witness in aBody/@wit, but instead uses the corresponding witness's @shortname instead of the abbreviation. The problem comes in sorting. If I use <xsl:sort select="name()"/> which bases it on the abbreviation separated off from the set of IDREFS then everything is sorted fine: "Blort-A, Blort-B, FOO" but using the @shortnames: "Blort in Version A, Blort in Version B, A Foo Manuscript" Obviously, this doesn't look alphabetically to the users, since A Foo should come before Blort. But, if I change it to: <xsl:sort select="$mss//[EMAIL PROTECTED](current())]/@shortname" /> which would do this, I get a NullPointerException from Xalan. Any suggestions? I looks really silly to not have this be sorted alphabetically. XSLT appended below.
