jstl 1.1.2, xml - how to concat two variables?
Hi,
I wasn't able to figure out, how to concat two variables (xml-document and
xpath-expression).
The documentation says that "XPathExpression" in <x:set var="" select="">
should be a string literal... What is the way to use a variable
XPathExpression to select an xml-fragment? I don't want to hard-code it in
the JSP. In case it's not possible to concat two variables, what would be
the alternative to do that? SAX-filter?
Best regards,
Wadim

<x:parsevar="xml"xml="${doc}"/>
<x:setvar="test"select="$xml$xpath"/> <!-- DOESN'T WORK!!! , hard-coded
xpath works... -->
<x:outselect="{$test}"/>

Problem solved another way around: JSP which returns an XSL-Stylesheet.
