Is there a utility function to map string->qname in the context of
an Element?
If there isn't yet, we should add one (Axis 1's MessageElement has
this, and it's generally hugely useful).
I've done it, just dont know
Thanks Steve!
1. where to put it
Shouldn't it be OMElement.resolve (String)? Eran?
OMElement.getQNameFromString(String) or
OMElement.resolveQName(String)
either works for me.
OK. do you want to do the tests then :)
2. what the failure policy should be. Return null vs throw exception?
Exception seems more right to me.
Really? I was thinking null would be better to avoid a ton of try/catch
blocks.
QName foo = element.resolveQName("foo:bar");
if (foo != null) {
// do something useful
}
vs.
QName foo = null;
try {
foo = element.resolveQName("foo:bar");
} catch (NoNamespaceException e) {
// fail
}
// do something useful
I just find it easier to write code like the first style, where I can
declare and assign the variable in the same place without wrapping
*everything* in try/catch.
It really depends what you want to do. Sometimes null is good; sometimes
exceptions (it would probably be that runtimeexception derivative
OMParserException) is better.
you could have both:
resolveQName(string s)
resolveQNameExcepting(string s) throws OMParserException
