It really depends on what site you are trying to get data from, but if it was a general purpose site, you could consider using screen scraping.
I have CDO, it's OCD with the letters in the right order; just as they ruddy well should be
Forgive your enemies - it messes with their heads

What does Google tell you about screen scraping? Now that I've given you a hint as to what topic to look for, it's time for you to hone your researching chops.

Take a look at
XPath. XPath allows you to query a specific fragment of a document which contains data you need (e.g. lottery results). However, the .NET FrameworkXPathis not appropriate for HTML since it is not tolerant for errors. Real HTML pages contain a lot of errors and usually they are not valid XML documents.

I disagree that screen scraping would be a good solution for quering a web site, especially if you have access to a HTML content. I would take it as a last choice and only if I had nothing but a screen, which I can barely imagine.

Screen scraping is also a term used to describe scraping content from a website, especially as he has already said he doesn't have an API available, and that there's no guarantee that the site is XHTML compliant.

I hate to argue on terminology, but I suppose you meant web scrapping[^]. The site does not really have to be XHTML compilant to query it (e.g. when using the library I mentioned in my another post). Ehm, whatever. Have a nice day/night or whatever currently is present in your time zone. :)

I use HtmlAgilityPack quite extensively as part of an automated testing framework (think; make HTTP request, get HTML response, check expectations using XPath). I found out yesterday, much to my chargrin, that it does not properly support attribute syntax. //someElement/@someAttribute should return
someAttribute, it actually returnssomeElement- making it totally non xpath compliant. Bit of a bugger IMO. -

I stand (well sit actually) corrected. I've run into problems attempting scraping with Html Agility Pack in the past, so have tended to avoid it. Newer versions might have improved it somewhat. Have a 5 to correct whoever 2 voted it.
