    Default Hoe do I read html from the web?

    I want to write a program that allows user input, then returns a certain value based on that input. Let me illustrate:

    HTML Code:
    <tr class="dataSmall stripe"> 
    					<a href="/finance/stocks/overview?symbol=PNX.N">PNX.N</a> 
    					<td class="data">2.40</td> 
    					<td class="data changeUp">+0.86</td> 
    Say the user input was PNX.N, and I wanted to return the value for the class "data changeUp", where would I even begin?

    How can I write a program that reads values from the html?

    Is this Javascript? Then you need to find a Javascript forum.

    Is this Java? Then you need a html parser. Search the net.

    If you need to change an HTML page, as junky said you need javascript (not java) - read the page via AJAX and update the html accordingly
