Jsoup

1.解析attribute中值

package com.xxx.parser.qy;

import org.jsoup.Jsoup;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * Created by user on 2017/6/6.
 */
public class sheet {
    public static void main(String args[]) {
        String str = "<Root>\n" +
                "<Item serviceID=\"16\" serviceName=\"住家保姆\" />\n" +
                "<Item serviceID=\"17\" serviceName=\"不住家保姆\" />\n" +
                "</Root>";
        List<Map<String, Object>> resultList = new ArrayList<Map<String, Object>>();
        org.jsoup.nodes.Document doc = Jsoup.parse(str);
        org.jsoup.select.Elements links = doc.getElementsByTag("Item");
        for(int i=0;i<links.size();i++){
            Map<String,Object> map = new HashMap<String, Object>();
            map.put("serviceid", links.get(i).attr("serviceid"));
            map.put("serviceName", links.get(i).attr("serviceName"));
            resultList.add(map);
        }
    }
}

2.解析节点值

package com.xxx.parser.qy;

import org.jsoup.Jsoup;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

/**
 * Created by user on 2017/6/6.
 */
public class sheet {
    public static void main(String args[]) {
    String str = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
            "<data>\n" +
            "<ITEM>\n" +
            "<ID>201203210001</ID>\n" +
            "<TITLE>xxx</TITLE>\n" +
            "<RELEASE_DATE>20110824</RELEASE_DATE>\n" +
            "<SOURCE>xxx</SOURCE>\n" +
            "<CONTENT>xxxxxx</CONTENT>\n" +
            "</ITEM>\n" +
            "\n" +
            "<ITEM>\n" +
            "<ID>201203210002</ID>\n" +
            "<TITLE>xxx</TITLE>\n" +
            "<RELEASE_DATE>20110824</RELEASE_DATE>\n" +
            "<SOURCE>xxx</SOURCE>\n" +
            "<CONTENT>xxxxxx</CONTENT>\n" +
            "</ITEM>\n" +
            "</data>";

        List<Map<String, Object>> resultList = new ArrayList<Map<String, Object>>();
        org.jsoup.nodes.Document doc = Jsoup.parse(str);
        org.jsoup.select.Elements links_id = doc.getElementsByTag("ID");
        org.jsoup.select.Elements links_title = doc.getElementsByTag("TITLE");
        org.jsoup.select.Elements links_date = doc.getElementsByTag("RELEASE_DATE");
        org.jsoup.select.Elements links_source = doc.getElementsByTag("SOURCE");
        org.jsoup.select.Elements links_content = doc.getElementsByTag("CONTENT");
        for(int i = 0;i<links_id.size();i++){
            Map<String, Object> resultMap = new HashMap<String, Object>();
            resultMap.put("id", links_id.get(i).text());
            resultMap.put("title", links_title.get(i).text());
            resultMap.put("relDate", links_date.get(i).text());
            resultMap.put("source", links_source.get(i).text());
            resultMap.put("content", links_content.get(i).text());
            resultList.add(resultMap);
        }
    }
}

3.解析html

1>根据"td"或者"tr"来解析
     org.jsoup.nodes.Document doc = Jsoup.parse(resHtml);
     org.jsoup.select.Elements links = doc.getElementsByTag("td");
     循环获取td中的值：
     links.get(i).text();

2>根据"class"参数来解析,如 <div class=".jtpsoft">...
     org.jsoup.nodes.Document doc = Jsoup.parse(resHtml);
     org.jsoup.select.Elements links = doc.select(".jtpsoft");
     然后根据links里面的 td或者tr标签来解析

3>根据 "name"参数来解析
    org.jsoup.nodes.Document doc = Jsoup.parse(resHtml);
    org.jsoup.select.Elements _links1 = doc.select("[name=zgzh]");
    org.jsoup.select.Elements _links2= doc.select("[name=sfzh]");
    如有多个name参数相同的值，则循环输出 _links1.get(i).val();
    取第一个值也可以使用_links1.first().val();

4.节点选择器
