Thread: 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"> 
					<td> 
					<a href="/finance/stocks/overview?symbol=PNX.N">PNX.N</a> 
					</td> 
					<td class="data">2.40</td> 
					<td class="data changeUp">+0.86</td> 
					 
				</tr>

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
