The first should work. The second in not valid, neither by JSTL spec, nor by XPath spec. The latter says, [36] VariableReference ::= '$' QName I have not actually tried it, though. JSTL spec says: [quote] An XPath expression must also treat variables that resolve to implementations of standard DOM interfaces as representing nodes of the type bound to that interface by the DOM specification. [/quote] 1) What is the structure of your document 2) Maybe: try to select a specific XML element and put it into JspContext's attribute.
