Question

I have an HTML source code in one String. I want to get a part of string using indexOf and lastIndexOf, but I only get integer

textView.setText("");
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
// Get the response

ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response_str = client.execute(request, responseHandler);

//response_str.lastIndexOf("morning—the sixth day.");
textView.setText( response_str.indexOf("<div class='commentary-link'>"););

I want to get a part of HTML code, and don’t know how to do that.

thanks all

Answer 1

indexOf returns an int, which represents the last index of the substring in the whole string. Use this index to with String#substring() get a sub-string of the original:

int index =  response_str.indexOf("<div class='commentary-link'>");
textView.setText( response_str.substring(index));

The use of lastIndexOf is pretty much the same:

int index =  response_str.lastIndexOf("<div class='commentary-link'>");
textView.setText( response_str.substring(index));
