Subject: Output redirection in LotusXSL/xalan: using a variable? From: Wolfgang May <may@xxxxxxxxxxxxxxxxxxxxxxxxxx> Date: Wed, 5 Jul 2000 16:52:39 +0200 (MET DST) |
Is it possible to use an xsl:variable for output redirection with LotusXSL/xalan? I am trying to compute the name of the output file in the xslt-stylesheet. This works with xt, but not for LotusXSL: <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:redirect="org.apache.xalan.xslt.extensions.Redirect" extension-element-prefixes="redirect">; <xsl:output method="xml" indent="yes"/> <xsl:template match="mondial"> <xsl:variable name="output_file_name"> <xsl:choose> <xsl:when test="@restrictions"> <xsl:variable name="restrictions" select="@restrictions"/> <xsl:value-of select="concat('mondial-',$restrictions,'-2.0.xml')"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="'mondial-2.0.xml'"/> </xsl:otherwise> </xsl:choose> </xsl:variable> <redirect:write select="{$output_file_name}">; <!-- ^^^^^^^^^^^^^^^^^^ the following works: <redirect:write select="@restriction">; or, with xt: <xt:document href="{$output_file_name}"> --> <xsl:text disable-output-escaping="yes"> <!DOCTYPE mondial SYSTEM "mondial-2.0.dtd"> </xsl:text> <mondial> <xsl:apply-templates select="*"/> </mondial> </redirect:write> <!-- </xt:document> --> </xsl:template> *** the input file <mondial restrictions="europe"> <continent id="europe"> <name>Europe</name> <area>9562488</area> </continent> ... </mondial> , so $output_file_name above should have the value "mondial-europe-2.0.xml", but I get ... *** the error message: malta:~/tmp> java org.apache.xalan.xslt.Process -in mondial-europe-flat.xml -xsl mondial-2.0.xsl ========= Parsing file:/home/may/tmp/mondial-2.0.xsl ========== Parse of file:/home/may/tmp/mondial-2.0.xsl took 1242 milliseconds ========= Parsing mondial-europe-flat.xml ========== Parse of mondial-europe-flat.xml took 3871 milliseconds ============================= Transforming...
