xml示例：
<ResponseContent><Parameter><Document><RecordSet id="1"><Master name="purchase"><Record><Field name="orderNumber" value="1P05-151200172"/><Field name="status" value="Y"/><Field name="plant" value="MFL01-1"/></Record></Master></RecordSet></Document></Parameter></ResponseContent>java解析代码获取Field name="status" 的value值：
package com.customcode.code;import java.io.ByteArrayInputStream;import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;import org.w3c.dom.Document;
import org.w3c.dom.Element;import org.w3c.dom.NodeList;public class ERPGETPARAM {public static String statusresult(String xml) throws Exception {DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();DocumentBuilder db = factory.newDocumentBuilder();Document document = db.parse(new ByteArrayInputStream(xml.getBytes()));NodeList node = document.getElementsByTagName("Field");//for(int i=0;i<node.getLength();i++){Element element = (Element)node.item(1);// 获取属性学号
// String name = element.getAttribute("name");
// System.out.println("name：" + name);String value=null;try{value = element.getAttribute("value");}catch(NullPointerException e){e.printStackTrace();}//System.out.println("value：" + value); return value;//获取值
// content = element.getElementsByTagName("value").item(0).getFirstChild().getNodeValue();
// System.out.println("value：" + content);//}}
}
main方法运行结果：
