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
