Scope question

[heed heed <he...@yahoo.com>]

Could someone please tell me how Xalan scopes the
variables "tag_name" and "tag_value" as shown below:

      <xsl:for-each select="./coverageType">
            <xsl:variable
name="tag_name"><xsl:value-of
select="name()"/></xsl:variable>
            <xsl:variable
name="tag_value"><xsl:value-of
select="."/></xsl:variable>
            <xsl:choose>
               <xsl:when test="@writeable!='true'">
                  <input type="text"
name="{$tag_name}:{$counter}" value="{$tag_value}"
size="18" maxlength="30"/>
               </xsl:when>
               <xsl:otherwise>
		  <xsl:value-of select="."/>
               </xsl:otherwise>
            </xsl:choose>
         </xsl:for-each>

Should I not be able to access these variables from
within the choose tag?

Good luck with your migration.  Please be sure to let us know of any
other suspected Xalan problems so we can check them out.

Gary - Thank you for responding to my question.

We fixed the problem by changing our XSL, which was
being transformed via Bluestone (com.bluestone.xml)
package (I believe they were/are using an old version
of the Lotus processor? I could be wrong.) 

We are moving an e-com app from Bluestone to Tomcat
3.2.1 and Xalan/Xerces and have had relatively few
problems that weren't caused by weird Bluestone
behavior.  We're trying very hard to refactor our XSLs
to spec during this port, and we've found a couple of
instances where Xalan handles our XML a bit
differently.

For example, in the code snippet that I sent to the
list, the 'writable' tag was being held onto by a
Bluestone object and referenced by the Bluestone
processor (somehow).  Xalan had no idea what the
'writable' tag was, or where it came from because we
have cleansed Bluetone-spectific code from our
application.

Thanks again for your help.

Yes.  You should.  If you're having a problem, please send along your
XML and complete XSLT and we'll see if we can reproduce it.
