RE: [xsl] Need to output an opening or closing tag by itself

Hi David,

has been shown before on this list.
Have a look at the following thread: 
http://www.biglist.com/lists/lists.mulberrytech.com/xsl-list/archives/20
0401/msg00694.html 

The selection you need in a template that handles e[(_at_)t='a'] looks like
this: 

following-sibling::*[generate-id(preceding-sibling::e[1]) =
generate-id(current()) and following-sibling::e[1]/@t='b']

But that is just one approach.
You may also want to skip processing of e[(_at_)t='b'].

I suggest you dive into the xsl-list archive...

Cheers,
Peter

Subject: [xsl] Need to output an opening or closing tag by itself

I have a simple XSLT problem for the gurus.


This is my input document:
<root>
 <e t="a"/>
 <f/>
 <f/>
 <e t="b"/>
</root>


This is the output document I want to produce:
<root>
 <e>
   <f/>
   <f/>
 </e>
</root>


This is the stylesheet I wrote to do the transformation:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
 version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

 <xsl:template match="/root">
   <root>
     <xsl:apply-templates/>
   </root>
 </xsl:template>

 <xsl:template match="e">
   <xsl:choose>
     <xsl:when test="@t ='a'">
       <e>
     </xsl:when>
     <xsl:when test="@t ='b'">
       </e>
     </xsl:when>
     <xsl:otherwise>
       <xsl:message terminate="yes">
         Unexpected data in attribute t.
       </xsl:message>
     </xsl:otherwise>
   </xsl:choose>
 </xsl:template>

 <xsl:template match="f">
   <xsl:copy/>
 </xsl:template>
</xsl:stylesheet>


Here is the Saxon output:
$ java -jar "c:\Program Files\Saxon\saxon9.jar" -o out.xml 
in.xml test.xslt Error on line 16 column 9 of
file:/C:/Documents%20and%20Settings/DFREY/Desktop/test/test.xslt:
 SXXP0003: Error reported by XML parser: The element type "e" 
must be terminated by the
 matching end-tag "</e>".
Failed to compile stylesheet. 1 error detected.


I understand that the source of the error is that the XSLT 
file is not valid XML because the <e> tag doesn't have a 
matching </e> tag in the right place.

How can I work around this issue to solve my problem?

Thanks,
David
