Create a {@link XPath} expression.

@param expression      string with the XPath expression to create
@param doc             the document, whose namespace is bound to the XPath expression
@param namespacePrefix prefix of the document namespace, that is bound to the XPath expression
@return the created XPath expression
@throws JaxenException if the XPath is not creatable
Create a { @link XPath } expression .
