Subject: Re: variable using other variable? Works in Saxon, not in Xalan From: "Benoit Cerrina" <benoit.cerrina@xxxxxxxxxxx> Date: Sun, 5 Nov 2000 16:45:32 +0100 |
Hi, this is a xalan1.2 bug which is under correction, the problem only comes with global variable. This never surfaced before xalan1.2 because previous version including 1.2D02 evaluated the global variable in document order (as seem natural) however in 1.2 the order is reversed. Therefore a quick fix is to change the order of your variable declaration so the variable which you need (dbquery) is defined after the one you where you use it (dbresult). This should change since they (the xalan team are changing the way those are handled) and order will not matter at all.

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, -- Thorbj?ørn Ravn Andersen "...sound of...
