I said what I said after reading the latest STX spec and only in the
context of this discussion (which is "taming SAX"). I have to agree with
Uche in saying that STXPath is very nice-- but may not be exactly what
we are shooting for. Surely predicates are viable in many cases in
partial scans such as:
<foo>
<bar>
<baz/>
</bar>
<bar test="foo">
<baz/>
</bar>
</foo>
/foo/bar[@test="foo"]/baz
But when considering /foo/bar[baz3="test"]/baz1
<foo>
<bar>
<baz1/>
<baz2/>
<baz3>test</baz3>
</bar>
</foo>
This predicate's value cannot be ascertained at the point of the baz1
startElement event in a single event look ahead model. At least that is
what I heard through the grapevine.
