Isolating a link in RSS Feed

I am new to programming so please go easy on me, I have been messing around with a simple RSS Reader, trying to get the link to the artice to open in a webview when the user clicks on the article.

I have found the string that controls and stores the link but when I try to print the link in the toast the link appears but with the whole article publishing date ect... how can I get the link to print on it own and what commands do I need to use to pass the link to the webview once I have isolated it, here is some of the code I have

RSSActivity

public class RssActivity extends ListActivity {
    private RssListAdapter adapter; 

        /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        List<JSONObject> jobs = new ArrayList<JSONObject>();
        try {
            jobs = RssReader.getLatestRssFeed();
        } catch (Exception e) {
            Log.e("RSS ERROR", "Error loading RSS Feed Stream >> " + e.getMessage() + " //" + e.toString());
        }

        adapter = new RssListAdapter(this,jobs);
        setListAdapter(adapter);
    }
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        // Get the item that was clicked
        Object o = this.getListAdapter().getItem(position);
        adapter.getItem(position).toString();
        String link = o.toString();


        Toast.makeText(this, "You selected: " + link, Toast.LENGTH_LONG)
                .show();


    }

}

If you have the URL or URI object at one point, probably one of the explanations in the links above will get you on your way.

-- Edit:

protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    // Get the item that was clicked
    Object o = this.getListAdapter().getItem(position);
    adapter.getItem(position).toString();
    String link = o.toString();
    Toast.makeText(this, "You selected: " + link, Toast.LENGTH_LONG)
            .show();
}

Guessing this is the code to show the link but if you don't supply us what the getListAdapter() method etc do then I'm afraid it's hard to help you out.

Try this

protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);
        // Get the item that was clicked
        JSONObject o = (JSONObject) this.getListAdapter().getItem(position);
        adapter.getItem(position).toString();
        String link = o.getString("NameOfLinkInJsonObject");


        Toast.makeText(this, "You selected: " + link, Toast.LENGTH_LONG)
                .show();

        mMyWebView.loadUrl(link);
    }

Be aware that you need to fix "NameOfLinkInJsonObject".

In your activity add a field like so

private WebView mMyWebView;

In your onCreate method add a

mMyWebView = (WebView) findViewById(R.id.webViewId);

You will have to change the R.id.webViewId to the appropriate id for your web view.
