Question

i just want to parse two values from a html file .

there will be several list elements in the html file and i want to parse two values

a. 1 ,100, 101
b. Swargate to Shivajinagar Circle route , Mnapa bhavan to.. ,Kothrud depot to…

i have used the below code to parse it, but i am not getting the required values , here i am getting href value only.

please give me any solution for the above problem

   String html =

   "<li/><a href=r361.html>1</a> Swargate to Shivajinagar Circle route"+
  " <li/><a href=r511.html>100</a> Manpa bhavan to Hinjewadi phase 3"+
   "<li/><a href=r572.html>101</a> Kothrud depot to Kondhava Bu";

   Reader reader = new StringReader(html);
   HTMLEditorKit.Parser parser = new ParserDelegator();
   final List<String> links = new ArrayList<String>();

   parser.parse(reader, new HTMLEditorKit.ParserCallback(){
       public void handleStartTag(HTML.Tag t, MutableAttributeSet a, int pos) {
           if(t == HTML.Tag.A) {
               Object link = a.getAttribute(HTML.Attribute.HREF);
               if(link != null) {
                   links.add(String.valueOf(link));
               }
           }
       }
   }, true);

   reader.close();
   System.out.println(links);

}

UPDATE:

Now i am getting the value of a href using below code (using JSOUP Lib)

AssetManager assetManager = getAssets();
InputStream ims =assetManager.open(“index.html”);
Document doc = Jsoup.parse(ims, “UTF-8”, “btc.com”);
Elements busNum = doc.getElementsByTag(“a”);
pTagString = busNum.html();

Log.i(“hh”,” onPostExecute =”+PTagString);

Now i want to get the Value out side the a href for eg: Swargate to shivajinagar circle route.

anybody know the method or any idea

You don’t even need to use a parse for this. You could use a regular expression.

See this Tutorial about regex in Java

And then you’ll need something like this:

<a[^>]*>([^<]*)<[^>]*>(.*)

as your regular expression. Then you will have both values you need in no time. It’s much more performant than parsing the html.
