I'm looking for a way to populate a listview or grid control with the contents of an HTML table from on of our intranet sites. What can I use to parse HTML tables?

The best approach would be using the Document Object Model interface:

Look up the IHtmlDocumentX etc. interfaces. Typically you would:

- acquire the IHtmlDocument somehow (depends on your app)
- Get the IHtmlElement for the Table (depends of the page, best would be giving the table an "id=" attribute)

- QI for IHtmlTable
- IHTmlTable::rows returns an IHtmlElementCollection of the rows, where each element can be QI'd for IHtmlTableRow itf
- IHTmlTableRow returns an IHtmlElementCollection of the rows, where each element can be QI'd for IHtmlTableCell itf

(you can use Colums instead of Rows)

DOM is part of Java, correct? I need a solution in C++ / MFC.

No, the HTML DOM is implemented a COM objects, so you can use it in all MS languages. Just #import <mshtml.dll> and you have everything you need (You could also use "Add From Type Library" in the clazz wizard if you're strictly MFC; but I find the #import - generated classes better)

It might be a bit of a hassle if you are new to COM, but it's definitely easier & more flexible than writing your own parser..

Go to MSDN, and type IHTMLDocument in the index - will give you a starting point.

I would even whip out a sample application - but I don't know if I find the time this weekend.
