There are various options. Depending on the use case

1. You can use xpath
2. Use regex by passing the XML as a string
3. Use binding mechanisms such as JAXB
4. Use parsers such as DOM or SAX

Create a DTO(e.g XmlDto) for attributes in this XML structure and use fromXML(<XML String>) method of XStream class available in java. Then you may use like this :

String request = "XML input string";
private XStream xstream;
XmlDto fromXML = (XmlDto) xstream.fromXML(request);
return fromXML.getXmlDto().<get your attribute w.r.t structure defined>;
