Find a value in a string

I am scraping a page from the net and I have the page HTML code in a string, now I want to find the value MIAMI which is in here:


<A HREF="test2.cgi?city=MIAMI">MIAMI</a></td> <td>




Now Miami will be dynamic, so how can I search for like the text between... 
<A HREF="test2.cgi?city= and ">
