After searching and reading a while ..
With XSLT 2.0 there is an unparsed-text() function, that can be used to
read in the content of /etc/papersize and assign it to a variable.
Simply:
<xsl:variable name="system.paper.type"
select="unparsed-text('/etc/papersize')"/>
Then this variable can be evaluated and the page.type parameter can be
set accordingly.
The big problem: This function is currently not implemented (libxslt1.1
does not contain an implementation and saxon implements it with version
7.3, but we have 6.5.5; no idea about xalan atm).
I tried a replacement, looking like this:
<xsl:variable name="system.paper.type">
<xi:include href="file:///etc/papersize" parse="text" encoding="iso-8859-1">
<xi:fallback>
<xsl:message>xinclude error: file not found</xsl:message>
</xi:fallback>
</xi:include>
</xsl:variable>
but it always outputs 'xinclude error: file not found' (independent from
using a file://-handler or not). I guess, libxslt (I test with xsltproc)
does not know the xi:include element here.
So the only possibility atm [1] seems to be to "rewrite" /etc/papersize
(as /etc/papersize.xml) as XML-file (just adding a fake-element about
it's content) and then importing the content using document(). The
creation of the XML-version of /etc/papersize must IMO be done a) with a
script and cron or b) with an extension. The latter one is IMO only
possible using Java.
Any ideas or opinions?
[1] I'm still in discussion, how this could be realized, but it seems,
an easy solution (using e.g. the XSLT 2.0 function) is impossible atm.
Regards, Daniel
