[DUG] web scraping using IHTMLDocument2

Fri Jan 29 14:39:49 NZDT 2010

Thanks Cameron,

It does indeed have that header, how do I make this work?
  XMLDocument1.FileName := 'c:\temp\test.htm';
  XMLDocument1.Active := True;
Gives me various errors, I suspect that that the file is not valid xml, 
or is there some other way of parsing it?
