Summary: XPath handling only supports single reference to
variable
Product: Taglibs
Version: 1.2.0
Platform: PC
Status: NEW
Severity: normal
Priority: P2
Component: Standard Taglib
AssignedTo: [email protected]
ReportedBy: [email protected]
The XPath union expression "$src/root/x | $src/root/y" is not handled correctly
as only the first set of nodes is returned. For example, the JSP
<%@ taglib prefix="x" uri="http://java.sun.com/jsp/jstl/xml"; %>
<x:parse var="src">
<root>
<x>one</x>
<x>two</x>
<x>three</x>
<y>a</y>
<y>b</y>
</root>
</x:parse>
<x:forEach select="$src/root/x | $src/root/y">
<x:out select="."/>
</x:forEach>
only displays the "x" elements. Swapping the arms of the union operator returns
the "y" elements.
