LibXML doesn't find any nodes for my xpath expression
问题 I'm using xpath and LibXML in an iPhone app to find some nodes in an xml document. I'm a noob in xpath so probably i am doing something wrong. Here is the xml: <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <GetUserByEmailResponse xmlns="http://tempuri.org/"> <GetUserByEmailResult> <id>4006</id> <name>Kudor Gyozo</name>
