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>

总结：不想千篇一律，以上是你尝鲜的动力。
