Subject: [xsl] Evaluate xsl:param in Xalan extension element From: Paul Brady <paul.brady@xxxxxxxxxxx> Date: Tue, 26 Nov 2002 16:42:44 -0000 |
I have an extension element written for xalan which takes a parameter which specifies the name of a template to execute. It is really a dynamic call-template. I am trying to port the extension element from xalan v1.2 to v2.3.1. The problem I am having is that I can't figure out how to get the value of a parameter that was passed to the containing template. Example: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dynamicTemplate="org.apache.xalan.xslt.DynamicTemplate" extension-element-prefixes="dynamicTemplate"> <xsl:template match="/"> <xsl:call-template name="DocletContentBody"> <xsl:with-param name="docletTemplate">test</xsl:with-param> </xsl:call-template> </xsl:template> <xsl:template name="DocletContentBody"> <xsl:param name="docletTemplate"/> <dynamicTemplate:dynamicCallTemplate name="docletTemplate"> <xsl:call-template name="doesntMatter"> </xsl:call-template> </dynamicTemplate:dynamicCallTemplate> </xsl:template> <xsl:template name="test"> </xsl:template> </xsl:stylesheet> The Extension element is called dynamicTemplate. When called, it attempts to evaluate the value of the docletTemplate param. This specifies the name of the template to execute. My xalan 1.2 version achieved this by simply String strTemplateName = xslprocessorcontext.processor.getVariable(new QName(strName)).str(); But in the 2.3.1, it seems that parameters are somehow lazily evaluated and using getParam() or getVariableOrParam() always returns null? Any help would be greatly appreciated. Paul. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
