Parse BufferedReader - urgent

Question

I have been trying to figure out how to parse a String that I receive from a remote server. I receive the String as an InputStream which I then wrap in a BufferedReader.
//make URL connection
//populate requestString
//send requestString to URL connection
// Get response data.
BufferedReader input = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
I have tried the following two ways:
StringTokenizer: expecting a String as input, I cannot pass the BufferedReader.
StreamTokenizer: I can pass the BufferedReader however I have problems when trying to read it. For some reason it is only reading the separators ("=" and "&") and not the text. Here is the code:
StreamTokenizer st = new StreamTokenizer(input);
while (st.nextToken() != -1)
int temp = st.nextToken();
if (st.ttype == -3)
System.out.println(st.sval);
else if (st.ttype == -2)
System.out.println(st.nval);
else if (st.ttype == 10)
continue;
else
System.out.println("Next Token returned "+st.ttype);
Everytime it prints that nextToken() returns 61 and 38 (+ and &). What am I doing wrong? The String looks like "ResultCode=0&ResponseCode=00&AVSResponseCode=N" etc... The information that is important is everything between the & and =, not those symbols themselves.
This is really urgent - I appreciate your help.

OK, I think what is happening here is that my condition in teh while loop is causing the problem. I have:
while (st.nextToken() != -1)
int temp = st.nextToken();
//etc
Therefore the words that are missing are actually being parsed in the while condition, and when I enter the while loop the next Token is in fact the + or &.
How do I check if the StreamTokenizer has reached the end of the stream and there are no more tokens wihtout actually parsing a token?? There is no clear method as there is in StringTokenizer(hasMoreTokens()).
Appreciate any help.
