variable using other variable? Works in Saxon, not in Xalan
I have a snippet of code in a stylesheet looking like:
<xsl:variable name="dbquery">
<xsl:text>http://127.0.0.1:8080/servlet/db2xml.servlet.DB2XMLServlet?dbQuery=</xsl:text>
<xsl:text>select%20*</xsl:text>
<xsl:text>%20from%20collection%20</xsl:text>
<xsl:text>where%20name='PRICE'%20</xsl:text>
<xsl:text>and%20dataitemkey%20in%20(</xsl:text>
<xsl:value-of select="$stocknumbers"/>
<xsl:text>null)</xsl:text>
</xsl:variable>
<xsl:variable name="dbresult" select="document($dbquery)"/>
which constructs an URL in one variable and uses it as an argument to
document() in the next. I did it with two variables since I otherwise
would need three set of quotes. $stocknumbers is a string on the form
'1','2','3'
Saxon 5.4.1 executes this as I intended during development from the
command-line. Xalan 1.2 reports the following error (which I call from
a servlet which uses processor.process to execute the stylesheet)
XSL Error: pattern = 'document($dbquery)'
VariableReference given for variable out of context or without
definition! Name = dbquery, source tree node: #document
Which behaviour is correct?
How can I work around this problem with Xalan?
Thanks in advance for any replies,

Hi,
is your variable which use the other one a global variable there is a (now
well) known bug (regression) in Xalan 1.2 (it worked in all previous
versions) concerning the handling of global variables.
I hope the Xalan developer will find some time off from Xalan J 2 to correct
this bug. I thought I could look into it but something else came up and I
don't have the time.
