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

Not pretty, but this will work....

   <xsl:choose>
     <xsl:when test="@t ='a'">
       <xsl:text disable-output-escaping="yes">&lt;e&gt;</xsl:text>
     </xsl:when>
     <xsl:when test="@t ='b'">
       <xsl:text disable-output-escaping="yes">&lt;/e&gt;</xsl:text>
     </xsl:when>
     <xsl:otherwise>
       <xsl:message terminate="yes">
         Unexpected data in attribute t.
       </xsl:message>
     </xsl:otherwise>
   </xsl:choose>

...this is a slightly better solution...

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

 <xsl:template match="e">
     <xsl:if test="@t ='a' and ./following-sibling::e[1]/@t = 'b'">
                <e>
                        <xsl:for-each select="./following-sibling::f">
                                <xsl:apply-templates select="."/>
                        </xsl:for-each>
                </e>
     </xsl:if >
 </xsl:template>

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

2008/6/25 David Frey <dpfrey(_at_)shaw(_dot_)ca>:

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
