Hi Tom, This has already been reported and fixed. See:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6394 You can patch your local copy of the sources, or get the latest from CVS. You should file a new bug if this patch doesn't fix the problem. Thanks, Dave Thomas Munaretto <[EMAIL PROTECTED] To: [email protected] o.com> cc: Subject: Attributes in variables and xsl:copy-of problem 02/20/2002 05:07 AM Hi all, First of all, apologies if this is a newbie question (couldn't find anything similar in the archives or faq, though). I've stumbled upon a problem regarding xsl:variable and using this variable in an xsl:copy-of element. It seems that Xalan-C 1.3 ignores attributes defined in the variable if these attributes have a value of "", i.e. an empty string. Example: -------- Stylesheet: ----------- <?xml version ="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> <xsl:template match="/Request"> <xsl:copy-of select="$Info"/> </xsl:template> <xsl:variable name="Info"> <InsertedInfo attribute1=""/> </xsl:variable> </xsl:stylesheet> xml file: --------- <?xml version ="1.0"?> <Request> </Request> Passing the above stylesheet to XalanTransformer::compileStylesheet( ) and the xml file to XalanTransformer::transform( ) results in: <?xml version="1.0" encoding="UTF-8"?> <InsertedInfo/> i.e. the Attribute attribute1 of node InsertedInfo is missing. If, however, attribute1 contains some value, e.g. a blank <xsl:variable name="Info"> <InsertedInfo attribute1=" "/> </xsl:variable> the output is <?xml version="1.0" encoding="UTF-8"?> <InsertedInfo attribute1=" "/> i.e. the attribute is there. Trying the same with Xalan-J 2_2_D14, the attribute is always there, no matter whether it's value is "" or " ". I have to admit that I don't know whether this really is a Xalan-C or a Xalan-J problem or rather the Xalan-C developers interpreting the XSLT 1.0 standard http://www.w3c.org/TR/xslt (especially sections 11.2 and 11.3) differently from the the Xalan-J developers. Or quite simply me abusing xslt and/or xalan in some way. Any clues? Tom PS: I'm using Xalan-C 1.3, Xerces-C 1.6 on Sun Solaris 2.6, both compiled myself with Sun Workshop 6.2 (aka Forte 6.2). __________________________________________________ Do You Yahoo!? Yahoo!
