Question

Getting the HTML from the WebBrowser Control

Asked by: purplesoup

This is a question about the Microsoft Web Browser control. I have version 7 of IE, the project references c:\windows\system32\ieframe.dll, which has the following details:

File version: 7.0.5730.11
Created 17 Oct 2006 12:33:42

I am developing with VB 6 but this control gets used by a lot of IDEs and languages.

I thought this line would get me the HTML from the document currently loaded into a browser:

WebBrowser1.Document.documentElement.outerHTML

*but* here is my original HTML:

<html>
<body>
[Body]
<hr>
look at these characters &copy; and &reg;
<hr>
trademark = &#8482; = &#x0099; (or &#x2122; ) <br />
registered trademark = &#174; = &#x00AE;  <br />
service mark = &#8480 = &#x2120;  <br />
copyright = &#169; = &#x00A9;  <br />
sound recording copyright = &#8471; = &#x2117;  <br />
</body>
</html>

and this is what I get back from the control:

print WebBrowser1.Document.documentElement.outerHTML
<HTML><HEAD></HEAD>
<BODY>[Body]
<HR>
look at these characters © and ®
<HR>
trademark = ™ = ™ (or ™ ) <BR>registered trademark = ® = ® <BR>service mark = ? = ? <BR>copyright = © = © <BR>sound recording copyright = ? = ? <BR></BODY></HTML>

How can I stop it evaluating the special characters?

I had the same trouble when using this control. try the IPersistFile interface (sorry - this is in c++)

IWebBrowser2Ptr m_pFrameWB;
IHTMLDocument2Ptr m_docPtr;
IPersistFilePtr m_file;      
......

IDispatch *pdisp;
m_pFrameWB->get_Document(&pdisp);                              
pdisp->QueryInterface(IID_IHTMLDocument2,(void**)&m_docPtr);
pdisp->Release();

m_docPtr->put_designMode(T2OLE("On"));
m_docPtr->QueryInterface(IID_IPersistFile,(void**)&m_file);      
........

m_file->Save(T2OLE((LPCTSTR)dlg.GetPathName()),false);

other than that i think you may be out of luck... the IWebBrowser control loads the HTML into a DOM and probably discards the source

I'll accept this on the grounds that other searches reveal this is the only way to do it, however I can't get similar functionality within VB which is a real pain!
