MHT's are text files that are formatted like HTML Multi-Part emails are.  They use MIME boundaries to separate the sections and images are encoded in base64 like they would be in emails.  Here is the first few lines from an MHT I made from a phpinfo page.  If you just want the content between the tags in the HTML body, you'll have to have something 'parse' it out.

From: "Saved by Windows Internet Explorer 8"
Subject: phpinfo()
Date: Mon, 14 Mar 2011 15:44:56 -0400
MIME-Version: 1.0
Content-Type: multipart/related;
	type="text/html";
	boundary="----=_NextPart_000_0000_01CBE25E.C4F42950"
X-MimeOLE: Produced By Microsoft MimeOLE V6.0.6002.18263

This is a multi-part message in MIME format.

------=_NextPart_000_0000_01CBE25E.C4F42950
Content-Type: text/html;
	charset="Windows-1252"
Content-Transfer-Encoding: quoted-printable
Content-Location: http://bbpweb:811/getinfo.php

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" =
"http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd">
<HTML><HEAD><TITLE>phpinfo()</TITLE>
<META content=3D"text/html; charset=3Dwindows-1252" =
http-equiv=3DContent-Type>
<STYLE type=3Dtext/css>BODY {
	BACKGROUND-COLOR: #ffffff; COLOR: #000000
}

DaveBaldwin, if I knew the MHT parsing format (which I think is rather complex) I would have already written a parsing function for this purpose.

It is not that complex, it looks just like the source for an email that uses the MIME boundaries to separate the parts.  You can open an *.mht file in Notepad or any other text editor and see everything.

I have looked at the source code of a lot of different MHT files. They don't have enough similar structural information to make it possible to parse them.

If you are so sure about how easy it is to parse MHT files, please show me how to do it.
