** Version 0.5.2
xLib is a Javascript library which makes XPath a lot easier.


HOW-TO:
     var a = xLib.evaluate(STRING xpathExpression [, XPathResult.CONSTANT or NUMBER resultType [, FUNCTION namespaceResolver]]);  // Returns the XPath Object matching xpathExpression of the type resultType (ANY_TYPE by default)
     a.value = numberValue, stringValue or booleanValue (depends on resultType)
     a.node = a.singleNodeValue
     a.nodes(n) = function returning the n'th node of the XPath Object (equivalent of snapshotItem(n) or iterateNext() 'n' times)
     a.nodes(n).attribute(x [, y]) = if only x is provided, return getAttribute(x), otherwise return setAttribute(x, y)
