I have written an IE BHO that uses the IHTMLDocument2 interface to alter the HTML, i need to be able to get the complete modified source including all the tags <!DOCTYPE....<HTML>....</HTML>. the get_body->get_innerHTML only gives me the <BODY>.....</BODY> section, thats no good i need the lot.

I either need to have it as a sting (BSTR) or be able to save it to a file.

i have already seen the few questions on here that suggest get_body, please dont suggest them... it dont work how i want it to.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I've done this in C# but using IHTMLDocument3 object - however the following C++ should work

QI your IHTMLDocument2 to get an IHTMLDocument3 interface (hopefully) you'll get an IHTMLDocument3 interface back and from this you should be able to get what you want.

Here's the source (note: it's in the most basic form, i.e. no ATL etc. and for brevity all error handling has been removed).

IHTMLDocument3 pHTMLDoc3;
pHTMLDoc2->QueryInterface(IID_IHTMLDocument3, reinterpret_cast<void**>(&pHTMLDoc3);

IHTMLElement* pDocElem;



I've not tested this C++ code but converted it to C# (as I've been using the browser recently in C#) and it seems to produce everything <html> to </html>.

I'm pretty sure that'll work for IHTMLDocument2 ?
IHTMLDocument2 doesn't include the get_DocumentElement method. However there's another interface called HTMLDocument which also supports this method and can be used in place of IHTMLDocument3.

What about this...

HRESULT IHTMLDocument2::get_all(IHTMLElementCollection **p);

Its a zero based collection of all the elements in a webpage.
(see http://msdn.microsoft.com/workshop/author/dhtml/reference/collections/all.asp for more info)

the other option is 'tostring'  (http://msdn.microsoft.com/workshop/browser/mshtml/reference/ifaces/document2/tostring.asp)

I have used both of these (although a while ago) in visual basic, should act the same way for VC++ or whatever you are using.

ToString actually does that?  I voiced a thought about that in an earlier question but never actually tried it.

I'll get back to ya.

i have solved this by getting the IPersistFile interface from the IHTMLDocument2 object...

thanx anyway

sorry about the delay - since the update of the look & feel of EE the flash, adverts and animated gifs anoy slightly.

none of the solutions proposed here are really suitable because of the way IE alters the raw HTML in its object model. anyway i will split the points.
