jdom解析XML问题

Wanted__杰 2014-12-03 10:42:31

本人新手，用jdom解析一段xml老是不成功，tid获取为空，求解。



	 public static String getElementTextFromXMLString(String xmlString,String elementName) throws JDOMException, IOException{

		 String tidText="";

		 SAXBuilder   builder   =   new   SAXBuilder(); 

		 Document   doc   =   null; 

		 StringReader   sr   =   new   StringReader(xmlString); 

		 doc   =   builder.build(sr); 

		 Namespace   soap   =   Namespace.getNamespace("soap","http://schemas.xmlsoap.org/soap/envelope/"); 

		 Namespace   simota   =   Namespace.getNamespace("simota","http://www.chinamobile.com"); 

		 Element   root   =   doc.getRootElement(); 

		 Element   body   =   root.getChild( "Body",soap);   // 获取到Body

		// Element   ele   =   body.getChild( "PreOperationsReq",simota);   //TransactionID 

		 Element   tid = body.getChild(elementName,simota);

		 tidText   =  tid.getText(); 

		 return tidText;

	 }

要解析的XML



<?xml version="1.0" encoding="UTF-8"?>

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">

  <soap:Body>

    <simota:PreOperationsReq xmlns:simota="http://www.chinamobile.com">

      <simota:SeqNum>20121128175631069529</simota:SeqNum>

      <simota:SessionID>20121128175631027229</simota:SessionID>

      <simota:SessionType>2</simota:SessionType>

      <simota:TimeStamp>20121128175631</simota:TimeStamp>

      <simota:CommType>4</simota:CommType>
