How to get part of string?
<p>I make a request for a oAuth request token and I do that by visiting a special URL. The result of this request (content of page) is this, how can I get the auth_token form this?</p>

<pre><code>oauth_token=TBFdNoytaizrfMAWNZ6feqssNz3BsozHk5AesIioX8u8Ec&amp;oauth_token_secret=DtQ3jiUIe33VdRcBAKwVQJRWpgKtEHi3m1yl3k0nlsHCBj0&amp;oauth_callback_confirmed=true
</code></pre>
