您好我正在从webservices获取值。我想上面的字符串到XML转换有谁能够告诉你怎么字符串转换为XML文件中的Java

<?xml version="1.0" encoding="utf-8"?> 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

子节点来了这样USER_ID =“testpub2”我必须转换xnode和获得的价值如何隐藏的XML节点？并使用saxparser获取价值。我可以直接取值吗？

Answer 1

下面的代码将字符串转换为XML文档。一旦你有文件，你可以浏览节点，或者你可以写入一个文件等。

import java.io.*; 
import javax.xml.parsers.*; 
import org.w3c.dom.*; 
import org.xml.sax.*; 

public class Util { 

    public static Document stringToDom(String xmlSource) 
      throws SAXException, ParserConfigurationException, IOException { 
     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
     DocumentBuilder builder = factory.newDocumentBuilder(); 
     return builder.parse(new InputSource(new StringReader(xmlSource))); 
    } 
} 

Answer 2

public void writeFile(String yourXML){ 
    BufferedWriter out = new BufferedWriter(new FileWriter("outfilename.xml")); 
    try { 
     out.write(yourXML); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally { 
     out.close(); 
    } 
}
