XPath: Select class 具有特定属性名称的名称元素

Question

Having the following XML:

<exceptions>
    <exception name="LegacyException"        msg="ERREUR DU MODULE SERVEUR">
        <context name="default"    msg="ERREUR DU MODULE SERVEUR (%1$s) : %2$s" />
    </exception>
</exceptions>

How do I select exception name and context name via XPath?

Something like this:

  String className = "LegacyException";
  String contextName= "default";       
  String query = "//exception[@name='" + className + "' and context[@name='" + contextName+ "']]";
  XPathExpression<Element> xpe = XPathFactory.instance().compile(query, Filters.element());

Answer 1

This xpath expression

//exceptions/exception/@name
or 
//exception/@name

evaluates to

LegacyException

while this one

//exceptions/exception/context/@name 
or 
//context/@name

evaluates to

default
