实例一：获取指定两个标签之间的数据
XML数据格式：
<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <GetAlarmTypeResponse xmlns="YKITSJLW"> <GetAlarmTypeResult>报警,断电,调校,超量程,分站故障,不巡检,暂停,传感器故障</GetAlarmTypeResult> </GetAlarmTypeResponse> </soap:Body> </soap:Envelope>
目的：获取<GetAlarmTypeResult>和</GetAlarmTypeResult> 之间的数据
方法一：
package yk.bigdata.dl.ias.fileParse; import org.dom4j.Document; import org.dom4j.Element; import org.dom4j.io.SAXReader; import yk.bigdata.dl.ias.bean.BeanAlarmType; import java.io.ByteArrayInputStream; import java.util.ArrayList; import java.util.List; /** * @Author: cjj * @Date: Created in 11:09 2019/7/9 * @Description: */ public class AlarmTypeXmlFileParse { public static dom4jXml(String interfaceData) throws Exception{ List<Element> elementList = null; SAXReader sr = new SAXReader(); Document document = sr.read(new ByteArrayInputStream(interfaceData.getBytes())); // 传入需要解析的数据 Element root = document.getRootElement(); elementList = root.elements(); for (Element e : elementList) { // 解析标签下一级标签 Element e1 = e.element("GetAlarmTypeResponse"); List<Element> elementList1 = e1.elements(); for (Element el:elementList1){ System.out.println(e1.elementText("GetAlarmTypeResult")); } } } }
方法二：
// 获取指定标签的index int indexbegin = xmlStr.indexOf("<GetAlarmTypeResult>"); int indexend = xmlStr.indexOf("</GetAlarmTypeResult>"); System.out.println("<TrmSeqNum>的位置===" + indexbegin); System.out.println("</TrmSeqNum>的位置===" + indexend); // 截取指定index之间的数据 String jsonStr = xmlStr.substring(indexbegin + 25, indexend);
System.out.println(jsonStr);
实例二：获取指定标签下的所有子标签的值
XML数据格式：
<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <GetTagValueJsonResponse xmlns="YKITSJLW"> <GetTagValueJsonResult> <Table diffgr:id="Table1" msdata:rowOrder="0"> <AlarmState>调校</AlarmState> <TagKey>YK03112034112</TagKey> <TagName>1611运顺回风流CO</TagName> <Value>0</Value> <AlarmTime>2019-06-01T13:44:35.477+08:00</AlarmTime> <AlarmRtnTime>2019-06-02T16:48:05.333+08:00</AlarmRtnTime> <TimeInState>97410</TimeInState> <SysGroup>安全监测监控系统</SysGroup> <TagType>一氧化碳</TagType> <EngUnit>ppm</EngUnit> <DataType>1</DataType> <HiAlarmLimit>24</HiAlarmLimit> <LoAlarmLimit>0</LoAlarmLimit> <UnitName>小屯煤矿</UnitName> </Table> <Table diffgr:id="Table2" msdata:rowOrder="1"> <AlarmState>调校</AlarmState> <TagKey>YK03113022114</TagKey> <TagName>1811运顺管道红外甲烷</TagName> <Value>2.912</Value> <AlarmTime>2019-06-01T01:39:36.41+08:00</AlarmTime> <AlarmRtnTime>2019-06-01T03:07:36.377+08:00</AlarmRtnTime> <TimeInState>5280</TimeInState> <SysGroup>安全监测监控系统</SysGroup> <TagType>高浓度甲烷</TagType> <EngUnit>%CH4</EngUnit> <DataType>1</DataType> <HiAlarmLimit>0</HiAlarmLimit> <LoAlarmLimit>0</LoAlarmLimit> <UnitName>五轮山煤矿</UnitName> </Table> </GetTagValueJsonResult> </GetTagValueJsonResponse> </soap:Body> </soap:Envelope>
目的：获取<Table>标签下的所有子标签后面跟的值，创建一个对象，用对象来接收取出来的值。
