有没有解吸XML的代码例子，谢谢。进来说

摘要: 有没有解吸XML的代码例子，谢谢。进来说

我想要个完整的解吸XML的例子，sax,dom都行。servlet，查出来数据组装XML，解吸XML怎么写。小弟在线等，不剩感激

JDOM解析:
logger.info("开始解析businessfactoryname.xml文件......");
SAXBuilder sax = new SAXBuilder();
try {
Document doc = sax.build(path);
Element ele = doc.getRootElement();
logger.info("得到了根元素：" + ele.getName());
List list = ele.getChildren("factory-str-content");

Iterator it = list.iterator();
while (it.hasNext()) {

Element element = (Element) it.next();
String key=element.getChild("content-key").getTextTrim();
String value=element.getChild("content-value").getTextTrim();
BusinessFactoryName.factoryname.put(key,value);
}
logger.info("解析businessfactory.xml文件完成......");
}
catch (Exception ex) {
logger.info("BusinessFactory_XML异常......");
ex.printStackTrace();
}


businessfactory.xml文件:
<?xml version="1.0" encoding="gbk"?>

先生成XML然后在解吸啊。呵呵。不过先给你们发点分。在我写点吧。呵呵

---

还有10分。呵呵

顶.

恩，我写的是一个方法，传得参数是XML字符串，和要取得字段，字段要全的

---

XML有字串的，也有文件的，看你用哪种吧

好。我结贴。给分了。谢谢各位
