JSoup parsing HTML

Question

I am trying to parse a non well formed DTD html file which i retrieve by a inputstream with JSOUP, and get all the data in the TD fields. How can i do that with JSoup? I already looked at the http://jsoup.org/cookbook/ but i should need som example to get it started.

Thank you in advance.

I already tried the saxparser but i can`t get the DTD to work.

Edit: I am getting a force close, i need the JSoup in my AsyncTask. Here is the LOgcat:

Here is the AsyncTask code:

public class MyTask extends AsyncTask<String, Integer, String> {
    private Elements tdsFromSecondColumn=null;
}

protected String doInBackground(String... params) {
      InputStream inputStreamActivity = response.getEntity().getContent();

                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStreamActivity));
                StringBuilder sb = new StringBuilder();
                String line = null;

                while ((line = reader.readLine()) != null) {
                    sb.append(line + "\n");
                }

                /******* CLOSE CONNECTION AND STREAM *******/

                System.out.println(sb);
                inputStreamActivity.close();

                String kpn;
                kpn = sb.toString();

                Document doc = Jsoup.parse(kpn);
                Elements tdsFromSecondColumn = doc.select("table.personaltable td:eq(1)");
}

@Override 
    protected void onPostExecute(String result) { 
        //publishProgress(false); 
        TextView tv = (TextView)findViewById(R.id.lbl_top);

        for (Element tdFromSecondColumn : tdsFromSecondColumn) { 
            //System.out.println(tdFromSecondColumn.text()); 
            tv.setText("");
            tv.setText(tdFromSecondColumn.text());
        }
}
}

So, you have an InputStream and not an URL? You should then use the Jsoup#parse() method which takes an InputStream :

Document document = Jsoup.parse(inputStream, charsetName, baseUri);
// ...

The charsetName should be the charset the document is originally encoded in. You can leave it null to let Jsoup decide or fallback to UTF-8. The baseUri should be the URL from which the HTML was originally served. You can leave it null , you'll only not be able to resolve relative links.

But if you actually have the original URL, then you could also just use Jsoup#connect() :

Document document = Jsoup.connect(url).get();
// ...

Regardless of the way you obtained the Document , you can use CSS selectors to select elements of interest in the document. See also the Jsoup cookbook on that subject . Here's an example which extracts all the data from the 2nd column of the <table> with a class name of personaltable :

Elements tdsFromSecondColumn = document.select("table.personaltable td:eq(1)");

for (Element tdFromSecondColumn : tdsFromSecondColumn) {
    System.out.println(tdFromSecondColumn.text());
}

which results in:

€ 2,00
€ 10,00

€ 0,33
€ 12,00
€ 0,00
