Jsoup is a Java HTML parser that can be easily parsed by HTML.

1. Get title:

public class Testjsoup {public
	static void Main (string[] args) {
		Document doc;
		try {
			//Get document
			doc = Jsoup.connect ("http://news.ifeng.com/").
			Gets the body
			Element content = Doc.body ();
			Tag collection, is the title and link per page
			Elements divs = Content.select ("div");
			for (int i = 0; i < divs.size (); i++) {
				//Today's Headline News
				if ("box_02". Equals (Divs.get (i). attributes (). Get ("class")) {
					Elements titles = Divs.get (i). Select ("a");
					for (Element title:titles) {
						if (""!=title.text ()) {
							System.out.println (Title.text ());
Link
System.out.printlin (title.select ("a"). attr ("href");
		Exception e) {
			//TODO auto-generated catch block
			e.printstacktrace ();
		}
	}
}

2. Get news content:

public static void Main (string[] args) {
		Document doc;
		try {
			//get
			doc = Jsoup
					. Connect (
							"http://news.ifeng.com/world/special/malaixiyakejishilian/ Content-4/detail_2014_03/30/35274873_0.shtml ")
					. Get ();
			Gets
			the body Element content = Doc.getelementbyid ("main_content");
			Tag collection, is the title and link of each page
			Elements divs = Content.select ("P");
			for (Element ele:divs) {
				//If the label is a picture address
				if ("Detailpic". Equals (Ele.attributes (). Get ("class")) {
					System.out.println (Ele.select ("img"). attr ("src"));
				else {
					System.out.println (Ele.text () + "\ n");} \
		catch (Exception e) {
			//TODO Auto-generated Catch block
			e.printstacktrace ();
		}

3. Get video information:

This is the video message of some news, we need to parse the parameter information inside the script.

	Video
			s = p.select ("script");
			if (!s.isempty ()) {
				//Convert argument list to text
				String data = S.first (). data ();
				data = Data.replaceall ("var", "");
				String[] arr;

				arr= data.split ("',");
				for (int i = 0; i < arr.length i++) {
				//String str = arr[i];
				str = Str.replaceall ("flash_[\\s]{0,} = '", "");
				System.out.println (Str.trim ());
				}

				arr = Data.split (",");
				for (String Str:arr) {
					string[] ir = str.split ("=");
					System.out.println (Ir[0].trim () + ";" + Ir[1].trim ());
				}

Complete Example:

public class Artcle {private String artlink;
	Private Document Doc;
	Private Element ele;

	Private Elements eles;
	"http://news.qq.com/a/20141001/018175.htm?tu_biz=1.114.2.1" Public artcle (String str) {this.artlink = str;
		Public Document Getdoc (String web) {Document doc = null;
		try {doc = Jsoup.connect (web). get ();
			catch (IOException e) {//TODO auto-generated catch block E.printstacktrace ();
		return null;
	return doc;
		public void Getartcle () {if (null = = Getdoc (artlink))) {return;
		} ele = Doc.select ("Div#cnt-main-article-qq").
		Eles = Ele.select ("P");
			for (Element p:eles) {Elements s = null;
			Video s = p.select ("script");
				if (!s.isempty ()) {//Convert argument list to text String data = S.first (). data ();
				data = Data.replaceall ("var", "");

				String[] arr;
				arr= data.split ("',");
				for (int i = 0; i < arr.length i++) {//String str = arr[i]; str = Str.replaceall ("flash_[\\s]{0,} = ' "," ");
				System.out.println (Str.trim ());
				} arr = Data.split (",");
					for (String Str:arr) {string[] ir = str.split ("=");
				System.out.println (Ir[0].trim () + ";" + Ir[1].trim ()); }
			}
		}
	}
}

Attention:

1. The use of the method is still very simple, sometimes when parsing the Web page will throw IO exception, you pay attention to it.

2.//the argument list to text
String data = S.first (). data ();

It is important to convert the list of parameters in the script into string format, and then we can get the information we need by manipulating the string.
