大家好，XML解析不依赖任何Jar包的编写模式，关键词：Pattern、Matcher使用。
工具类如下
/**
* Xml工具类
* @author 章力
* @微信 zl4828
*/
public class XmlUtil {
/**
* 从消息message中提取出指定的tagName节点,包括他得子节点.
*
* @param xmlMessage
* @param tagName
* @return
* @throws Exception
*/
public static String pareXml(String xmlMessage, String tagName)
{
String regex = ".*?(<"+tagName+">.*?</"+tagName+">)|(<"+tagName+"/>)";
Pattern pattern = Pattern.compile(regex, Pattern.DOTALL);
Matcher matcher = pattern.matcher(xmlMessage);
if (matcher.find())
{
xmlMessage = matcher.group(1);
return xmlMessage;
}
else
{
throw new RuntimeException("无法提取xml消息体.tagName = " + tagName);
}
}
/**
* 从消息message中提取出指定的tagName节点中间的内容
*
* @param xmlMessage
* @param tagName
* @return
* @throws Exception
*/
public static String pareXmlContent(String xmlMessage, String tagName)
{
String regex = "\\<" + tagName + ">(.*?)\\</" + tagName + ">";
Pattern pattern = Pattern.compile(regex, Pattern.DOTALL);
Matcher matcher = pattern.matcher(xmlMessage);
if (matcher.find())
{
xmlMessage = matcher.group(1);
return xmlMessage;
}
else
{
throw new RuntimeException("无法提取xml消息体.tagName = " + tagName);
}
}
/**
* 返回匹配到的所有节点
*
* @param xmlMessage
* @param tagName
* @return
* @throws Exception
*/
public static Matcher pareXmlMatcher(String xmlMessage, String tagName)
{
String regex = ".*?(<"+tagName+">.*?</"+tagName+">)|(<"+tagName+"/>)";
Pattern pattern = Pattern.compile(regex, Pattern.DOTALL);
Matcher matcher = pattern.matcher(xmlMessage);
return matcher;
}
}
使用实例
/**
* 解析返回的XML，沫沫金提供支持微信@zl4828
*/
Matcher matcher = XmlUtil.pareXmlMatcher(resultXml, "Result");
while (matcher.find()) {
System.out.println(XmlUtil.pareXmlContent(matcher.group(),"hosName"));
}
示例XML内容
<?xml version="1.0" encoding="UTF-8"?> <Response><MessageHeader> <code>0</code> <desc>成功</desc> </MessageHeader><List> <Result> <hosOrgCode>43523202X61010311A1001</hosOrgCode> <hosName>西安市第九医院</hosName> <hospitalAdd>沫沫金</hospitalAdd> <hospitalRule></hospitalRule> <hospitalWeb></hospitalWeb> <trafficGuide></trafficGuide> <hospitalDesc>专注网页设计、Web前端工程</hospitalDesc> <hospitalTel>微信：zl4828</hospitalTel> <hospitalGrade></hospitalGrade> <payMode>|3|</payMode> <orderMode>|2|</orderMode> <isSpTime>1</isSpTime> </Result> <Result> <hosOrgCode>43720037161011311A5211</hosOrgCode> <hosName>西安市第八医院</hosName> <hospitalAdd></hospitalAdd> <hospitalRule></hospitalRule> <hospitalWeb></hospitalWeb> <trafficGuide></trafficGuide> <hospitalDesc>网络营销</hospitalDesc> <hospitalTel>15319419526</hospitalTel> <hospitalGrade>1</hospitalGrade> <payMode>|3|</payMode> <orderMode>|2|</orderMode> <isSpTime>1</isSpTime> </Result> </List></Response>
总结：不想千篇一律，以上是你尝鲜的动力。
