reading over my last paragraph, it's not clear what I meant, so here's a
second attempt. The current 3-19 nightly of XPathUtil.valueOf is below:
public String valueOf(Node n, String xpath) throws SAXPathException
{
staticInit();
XPath xp = new XPath(xpath);
return xp.valueOf(getLocalContext(n));
}
when it calls return, it the result of getLocalContext(node) to
XPath.valueOf(). when I output that result, I get zero length string.
the source for getLocalContext(node) is below.
private Context getLocalContext(Node n) {
// set up instance-specific contexts
VariableContext vc = new JstlVariableContext();
ContextSupport cs = new ContextSupport(nc, fc, vc, dn);
Context c = new Context(cs);
List l = new ArrayList(1);
l.add(n);
c.setNodeSet(l);
return c;
}
an instance of JstlVariableContext is passed to the constructor of
ContextSupport, but I don't see where
JstlVariableContext.getVariableValue() is called. Within
getLocalContext, should it check to make sure context was created
correctly when it does Context c = new Context(cs)?
when I output the result of the hsr.getHeader(localName), it never
reaches that chunk of code in getVariableValue().
else if (namespace.equals(HEADER_NS_URL)) {
HttpServletRequest hsr =
(HttpServletRequest) pageContext.getRequest();
return hsr.getHeader(localName);
thanks.
