### [string 转化xml xml转化为string][string _xml xml_string] ###

一、使用最原始的javax.xml.parsers，标准的jdk api

// 字符串转XML

**\[java\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  String xmlStr = \\"......\\";
2.  
3.  StringReader sr = new StringReader(xmlStr);
4.  
5.  InputSource is = new InputSource(sr);
6.  
7.  DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
8.  
9.  DocumentBuilder builder=factory.newDocumentBuilder();
10. 
11. Document doc = builder.parse(is);

//XML转字符串

**\[java\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  TransformerFactory tf = TransformerFactory.newInstance();
2.  
3.  Transformer t = tf.newTransformer();
4.  
5.  t.setOutputProperty(\\"encoding\\",\\"GB23121\\");//解决中文问题，试过用GBK不行 
6.  
7.  ByteArrayOutputStream bos = new ByteArrayOutputStream();
8.  
9.  t.transform(new DOMSource(doc), new StreamResult(bos));
10. 
11. String xmlStr = bos.toString();

这里的XML DOCUMENT为org.w3c.dom.Document

二、使用dom4j后程式变得更简单

**\[java\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  // 字符串转XML 
2.  
3.  String xmlStr = \\"......\\";
4.  
5.  Document document = DocumentHelper.parseText(xmlStr);
6.  
7.  
8.  
9.  // XML转字符串 
10. 
11. Document document = ...;
12. 
13. String text = document.asXML();
14. 
15. 
16. 
17. 这里的XML DOCUMENT为org.dom4j.Document

三、使用JDOM

JDOM的处理方式和第一种方法处理很类似

**\[java\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  //字符串转XML 
2.  
3.  String xmlStr = \\".....\\";
4.  
5.  StringReader sr = new StringReader(xmlStr);
6.  
7.  InputSource is = new InputSource(sr);
8.  
9.  Document doc = (new SAXBuilder()).build(is);
10. 
11. 
12. 
13. //XML转字符串 
14. 
15. Format format = Format.getPrettyFormat();
16. 
17. format.setEncoding(\\"gb2312\\");//配置xml文档的字符为gb2312，解决中文问题 
18. 
19. XMLOutputter xmlout = new XMLOutputter(format);
20. 
21. ByteArrayOutputStream bo = new ByteArrayOutputStream();
22. 
23. xmlout.output(doc,bo);
24. 
25. String xmlStr = bo.toString();
26. 
27. 
28. 
29. 这里的XML DOCUMENT为org.jdom.Document

四、JAVASCRIPT中的处理

**\[javascript\]** [ view plain][view plain] [copy][view plain] [print][view plain] [?][view plain]

1.  //字符串转XML 
2.  
3.  var xmlStr = \\".....\\";
4.  
5.  var xmlDoc = new ActiveXObject(\\"Microsoft.XMLDOM\\");
6.  
7.  xmlDoc.async=false;
8.  
9.  xmlDoc.loadXML(xmlStr);
10. 
11. //能够处理这个xmlDoc了 
12. 
13. var name = xmlDoc.selectSingleNode(\\"/person/name\\");
14. 
15. alert(name.text);
16. 
17. 
18. 
19. //XML转字符串 
20. 
21. var xmlDoc = ......;
22. 
23. var xmlStr = xmlDoc.xml
24. 
25. 
26. 
27. 这里的XML DOCUMENT为javascript版的XMLDOM
