BUG: Xalan does not manage document fragments variables
I need to process the same xml file several times in order to present
different statistics and reports in a html page.
I use a docfragment <xsl:variable> to describe what statistics i wont.
All works fine with IE5.0 + MSXML3 (June 2000) and with XmlSpy 3.0, but
Xalan is not able to process my stylesheet.
To make things easier to undersand, istead to enclose my original files
I enclosed two very simple files (x.xml and x.xsl) that
are able to produce the Xalan error.
--- COMMAND LINE

two stylesheets in an XML document?
Posted by Dave <LI...@sheffield.ac.uk>.
Hi,
I am quite new to Xalan.
I am using the DefaultApplyXSL servlet and trying to include
two <?xml-stylesheet ... > in an XML document, one for WML
and the other for HTML, i.e.:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet
href="http://localhost/project.nsf/workHtml.xsl?OpenPage"
type="text/xsl"?>
<?xml-stylesheet alternate="yes"
href="http://localhost/project.nsf/workWml.xsl?OpenPage"
type="text/xsl" media="up"?>
.....
But, this does not work.
When I include only one <?xml-stylesheet ...>, it works well.
So, I think each stylesheet is all right.
Is this a stupid question?
Or are there any other ways to get around this?
I tried to access the mail list for answers but, it was impossible.
Waiting for guru's answers...
Thanks.
Dave
Re: BUG: Xalan does not manage document fragments variables

Ulrico --
Xalan is actually in compliance with the XSLT standard (section 11.1)
while MSXML3 is not.
Your "docfragment" is actually called a "result tree fragment" and this
is what is bound to the variable "chars".
Regarding your statement:
<xsl:for-each select="$chars/c">
the standard states "It is not permitted to use the /, //, and []
operators on result tree fragments. This is why Xalan complains.
To convert the result tree fragment to a node-set, use the nodeset
extension function present in the latest version of Xalan. If you need
help using the nodeset extension function, just let us know.
