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
*/
publicclassXmlUtil{
/**
*从消息message中提取出指定的tagName节点,包括他得子节点.
*
*@paramxmlMessage
*@paramtagName
*@return
*@throwsException
*/
publicstaticStringpareXml(StringxmlMessage,StringtagName)
{
Stringregex=".*?(<"+tagName+">.*?</"+tagName+">)|(<"+tagName+"/>)";
Patternpattern=Pattern.compile(regex,Pattern.DOTALL);
Matchermatcher=pattern.matcher(xmlMessage);
if(matcher.find())
{
xmlMessage=matcher.group(1);
returnxmlMessage;
}
else
{
thrownewRuntimeException("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
*
*@paramxmlMessage
*@paramtagName
*@return
*@throwsException
*/
publicstaticStringpareXmlContent(StringxmlMessage,StringtagName)
{
Stringregex="\\<"+tagName+">(.*?)\\</"+tagName+">";
Patternpattern=Pattern.compile(regex,Pattern.DOTALL);
Matchermatcher=pattern.matcher(xmlMessage);
if(matcher.find())
{
xmlMessage=matcher.group(1);
returnxmlMessage;
}
else
{
thrownewRuntimeException("无法提取xml消息体.tagName="+tagName);
}
}
/**
*返回匹配到的所有节点
*
*@paramxmlMessage
*@paramtagName
*@return
*@throwsException
*/
publicstaticMatcherpareXmlMatcher(StringxmlMessage,StringtagName)
{
Stringregex=".*?(<"+tagName+">.*?</"+tagName+">)|(<"+tagName+"/>)";
Patternpattern=Pattern.compile(regex,Pattern.DOTALL);
Matchermatcher=pattern.matcher(xmlMessage);
returnmatcher;
}
}
使用实例
/** *解析返回的XML，沫沫金提供支持微信@zl4828 */ Matchermatcher=XmlUtil.pareXmlMatcher(resultXml,"Result"); while(matcher.find()){ System.out.println(XmlUtil.pareXmlContent(matcher.group(),"hosName")); }
示例XML内容
<?xmlversion="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。
