This will help U
<xsl:template match="gvsdb:list-people">
<xsl:variable name="class">
<xsl:choose>
<xsl:when test="string(@class)">
<util:include-expr>
<util:expr>

(XMLGenerator.toXML(<xsl:value-of
select="@class"/>Helper.getAll())).asXML()
</xsp:expr>

</xsp:expr>
</util:expr>
</util:include-expr>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
In the XSP File...
<gvsdb:list-people class="Singer"> for static
For dynamic
<gvsdb:list-people>
<class> <xsp-request:get-parameter name="class"/></class>
</gvsdb:list-people>
Note that the XSL handles both the cases
<gvsdb:list-people class="Singer" >
and
<gvsdb:list-people>
<class>Singer</class>
Hope this helps...

Subject: Tags: Passing dynamically generated values for parameters
I am stuck for the last two days, and having scourged the newsgroup
postings, I think a direct appeal is okay...
My entire project revolves around being able to do something like this,
and my go-live date is nearing, so please, h-e-l-p.
The problem is this:
I have a custom logic sheet with a method called list-people. It takes
in a parameter called "class", and calls the appropriate helper class to
do its stuff. The tag code looks like this:
<xsl:template match="gvsdb:list-people">
<xsl:variable name="class"/>
<util:include-expr>
<util:expr>
<xsp:expr>
(XMLGenerator.toXML(<xsl:value-of
select="@class"/>Helper.getAll())).asXML()
</xsp:expr>
</util:expr>
</util:include-expr>
</xsl:template>
In an xsp file called people.xml, I call this tag to populate a table,
like so:
<gvsdb:list-people class="Singer">
This works fine.
Now I try (in vain) to make this dynamic by getting the value of "class"
from an identically named request parameter. I tried a bunch of options,
such as:
<xsp:element name="gvsdb:list-people">
<xsp:attribute name="class">
<xsp:expr>
<xsp-request:get-parameter name="class"/>
</xsp:expr>
</xsp:attribute>
</xsp:element>
This one fails! Instead of executing the tag, it merely writes it out to
the output as
<gvsdb:list-people class="Singer">
How do I make this work and populate the table?
Best Regards,
Sreedhar Chintalapaty
