                         ParserConfigurationException,
                         XPathExpressionException

Parses an InputStream and returns a NodeList of the given xpath

Parameters:

in - the InputStream of the XML structure

namespaces - Map of namespaces

xPathStr - String with the xpath expression

Returns:

NodeList that is the result of the xpath expression

Throws:

IOException - if the input cannot be read

SAXException - if the input is malformed XML

ParserConfigurationException

XPathExpressionException - in case of an invalid xpath

getNodes

Returns a NodeList for the given xpath under a Node

Parameters:

startNode - the Node that is the root of the xpath

namespaces - Map of namespaces

xPathStr - String with the xpath expression

Returns:

NodeList that is the result of the xpath expression

Throws:

XPathExpressionException - in case of an invalid xpath
