[flexcoders] E4X wildcard/dynamic query

[Richard Rodseth]

Does attribute matching in E4X include some kind of wildcard value?

I'd like to be able to do something like:

nodes.node.(attribute( "a") == query.a && attribute("b") == query.b)

<nodes>
<node a="1">
</node>
<node a="1" b="2">
</node>
<nodes>

and have both nodes match if query.b is null.
