[General] Stax has an "XPath like"?

[cdeneux]

Your first need is to have "an easy method, understandable and standard for the newbie", and I think that XPath is the right one.

Your performance need through StAX is a second need.

I think that you will start to implement your XPath need. As XPath needs a full representation of the XML tree in memory, StAX can be used with XMLBeans to create this tree. Saxon is a good XPath engine, moreover it is compliant with XPath 2.0.

Example (putting Saxon librairies in the classpath) :

Code:
final XMLStreamReader xsr = xifThreadLocal.get().createXMLStreamReader(...);
final XmlObject xmlRequest = XmlObject.Factory.parse(xsr);
final XmlObject[] values = xmlRequest.selectPath("xpath_expression");
