Hi group,
I've run into a problem with E4X filters on namespaced elements. The
following example demonstrates the problem:
var xml = <atom:feed xmlns:atom="http://www.w3.org/2005/Atom";>
<atom:entry>
<atom:title>One</atom:title>
</atom:entry>
<atom:entry>
<atom:title>Two</atom:title>
</atom:entry>
</atom:feed>;
if (1) {
var atom = new Namespace("http://www.w3.org/2005/Atom";);
print(xml.atom::entry.(atom::title == "One"));
}
else {
default xml namespace = "http://www.w3.org/2005/Atom";;
print(xml.entry.(title == "One"));
default xml namespace = "";
}
The first part of the if () statement results in the following stack
trace when optimization is turned on (tested with rhino1_7R2-RC3.zip).
The second part works. Should I file a bug somewhere?
