Hi,

If the source code is XHTML compliant, use the nifty features of the XML namespace. Load it as an XML document and use XPath to select the nodes you want.

What are the features? And what is XPath?

The source doesn't look XHTML compliant so it looks like you are just going to have to hope the html code never changes. After you get the first line that you want, you will probably have to parse that line based on the second bold tag you come across. This is why screen scraping is not recommended, but sometimes there is no other choice. If someone takes the bold tags out then your code will not work correctly anymore. Just a chance you gotta take.

That is one of the great things about writing screen scrapers, putting terms in the contract which make you more money when the web source does change

Of course, this is when you are writing the code for someone else, who is much less programming savy
