Captured using the dom4j toolkit. Put the desired information in the class deal. java.

Deal. Java:

Package tuangou; import Java. util. arraylist; import Java. util. iterator; public class deal {private string cityname; private string dealtitle; private string dealurl; private string dealimg; private string dealdesc; private double value; private double price; private int salesmin; // The minimum number of participants is the private int salesnum; // The number of participants is the private int starttime; private int endtime; private arraylist <shop> shops; Public deal () {} Public String getcityname () {return cityname;} public void setcityname (string cityname) {This. cityname = cityname;} Public String getdealtitle () {return dealtitle;} public void setdealtitle (string dealtitle) {This. dealtitle = dealtitle;} Public String getdealurl () {return dealurl;} public void setdealurl (string dealurl) {This. dealurl = dealurl;} Public String getdealimg () {return dealimg;} public void setdealimg (string dealimg) {This. dealimg = dealimg;} Public String getdealdesc () {return dealdesc;} public void setdealdesc (string dealdesc) {This. dealdesc = dealdesc;} public double getvalue () {return value;} public void setvalue (double D) {This. value = D;} public double getprice () {return price;} public void setprice (double D) {This. price = D;} public int getsalesmin () {return salesmin;} public void setsalesmin (INT salesmin) {This. salesmin = salesmin;} public int getsalesnum () {return salesnum;} public void setsalesnum (INT salesnum) {This. salesnum = salesnum;} public int getstarttime () {return starttime;} public void setstarttime (INT starttime) {This. starttime = starttime;} public int getendtime () {return endtime;} public void setendtime (INT endtime) {This. endtime = endtime;} public arraylist <shop> getshops () {return shops;} public void setshops (arraylist <shop> shops) {This. shops = shops;} Public String tostring () {string STR = "cityname: \ t" + cityname + "\ n" + "dealtitle: \ t "+ dealtitle +" \ n "+" dealurl: \ t "+ dealurl +" \ n "+" dealimg: \ t "+ dealimg +" \ n "+" dealdesc: \ t "+ dealdesc +" \ n "+" value: \ t "+ value +" \ n "+" Price: \ t "+ Price +" \ n "+" salesmin: \ t "+ salesmin +" \ n "+" salesnum: \ t "+ salesnum +" \ n "+" starttime: \ t "+ starttime +" \ n "+" endtime: \ t "+ endtime +" \ n "; for (iterator <shop> I = shops. iterator (); I. hasnext ();) {shop = I. next (); STR = STR + shop. tostring () ;}return STR ;}}

Because a group purchase information may correspond to multiple consumption locations, you have to write a class shop. Java:

package tuangou;public class Shop {private String shopName;private String shopAddr;private String longitude;private String latitude;public Shop() {}public String getShopName() {return shopName;}public void setShopName(String shopName) {this.shopName = shopName;}public String getShopAddr() {return shopAddr;}public void setShopAddr(String shopAddr) {this.shopAddr = shopAddr;}public String getLongitude() {return longitude;}public void setLongitude(String longitude) {this.longitude = longitude;}public String getLatitude() {return latitude;}public void setLatitude(String latitude) {this.latitude = latitude;}public String toString() {String str = "shopName:\t\t" + shopName + "\n" + "shopAddr:\t\t"+ shopAddr + "\n" + "shopLongitude:\t\t" + longitude + "\n"+ "shoplatidude:\t\t" + latitude + "\n";return str;}}

In this case, the XML parsing class will be written below.

All right, you're done. Write a main test:

package com.meituan;public class testXML {public static void main(String args[]) {MeiTuanXmlParse mtp = new MeiTuanXmlParse();//mtp.parseXml("I:/projects/Andriod/myDo/APIXML/xml/meituanduan.xml");mtp.parseXml("C:/Users/mojia/Desktop/dom4j/task/meituandeals.xml");//System.out.println(mtr.toString());/*String name = "234523452.254"; if(name.matches("\\d+\\.?\\d*")){System.out.println("ok");}else System.out.println("no");*/}}
