currently I'm pulling text from a website using

public String getText(String uri) {
    HttpClient client1 = new DefaultHttpClient();
    HttpGet request = new HttpGet(uri);


    ResponseHandler<String> responseHandler = new BasicResponseHandler();
    try {
        String response_str = client1.execute(request, responseHandler);
        return response_str;

    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        return "";

    }
}

and I get a bunch of HTML code that is filtered with Html.fromHtml() which cleans up all the HTML text and leaves me with the dialog I want.

However t开发者_运维问答his method cannot let me set the title of the alert dialog because it only comes out as one string and cannot differentiate between whats in the parameters from the <body></body> parameters. It also doesn't filter out some comments such as

     <!--BODY{color:white; background-color:transparent;......

How can I delete the extra HTML text and separate the title portion from the main body of the text. Thank You

Take a look at Spannable string class.

"This is the interface for text to which markup objects can be attached and detached. Not all Spannable classes have mutable text; see Editable for that."

To parse HTML, use an HTML-Parser as there are some out there.

In the case that you control the formating/content of that pulled/desired HTML-Page, you'll want to switch from HTML to something better suited for your needs like a simple XML-Language or JSON.
