Strange problem trying to remove links from a html string

Hello, here I am again, with a new problem.
I parsed a html code in to a string, and then removed the unwanted parts at the start and end of the string, that was the easy part.
But take a look at this log output and then at the code.

01-31 06:19:13.486: D/HTML_inString part to remove->: <a href="/wedstrijd/1622160/psv---vitesse/">
01-31 06:19:13.486: D/Should still be the same->:<a href="/wedstrijd/1622160/psv---vitesse/">
01-31 06:19:13.606: E/AndroidRuntime: Caused by: java.lang.StringIndexOutOfBoundsException: length=4959; regionStart=848; regionLength=-605
01-31 06:50:28.805: E/AndroidRuntime: at com.kalder.android.FeyenoordActivity.onCreate(FeyenoordActivity.java:48)

Notice that both outputs are the same, still, it gives me a StringIndexOutOfBoundsException while the string to be removed is displayed correctly in the log...

Line 3 in the following syntax is line 48 in my java file.

                String temp = HTML_inString.substring(HTML_inString.indexOf("<a href=\"/wedstrijd/"),HTML_inString.indexOf("<span class=\"club-home\">"));
                Log.d("Should still be the same->", temp);
                HTML_inString = HTML_inString.replace("" + temp, ""); // I tried both with "" + and without that.
        } else {
                break;
        }
        try {
                Thread.sleep(100);
        } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        }
}
Parsed in 0.032 seconds,  using GeSHi 1.0.8.4

HTML_inString.indexOf("<span class=\"club-home\">") is the first index after the > from <a href=

so frankly it gives an error although the string to replace (temp) is correct.

I figured it out... because <span blabla didn't get changed at all it kept looking for the same <span blabla,
so i made it remove the < from <span, and at that point it started looping the links out including each < of <span, then after the while loop i replaceAll'ed them back in.
