[vwnc] XPath

> Hi,

> xml:

> Java solution:
>
> xpath =
> XPath.newInstance("/SOAP-ENV:Envelope/SOAP-ENV:Body/SOAP-CHK:Success/TEST:TABLE");
> xpath.addNamespace("SOAP-ENV",
> "http://schemas.xmlsoap.org/soap/envelope/");
> xpath.addNamespace("SOAP-CHK", "http://soaptest1/soaptest/");
> xpath.addNamespace("TEST", "urn:candle-soap:attributes");
> List<?> list = xpath.selectNodes( document );
>
> Note that the qualifier "TEST" had to be inserted and added
> (addNamespace(...)) because otherwise /TABLE refers to a node not beeing
> defined in a namespace. See also:
