System.OutOfMemoryException using Regex and Strings

I have exhausted all resources, so perhaps someone out there can help.

I have a 8MB string (that represents an html document) and I am trying to
run a couple of regular expressions on this string. I receive a
System.OutOfMemoryException.

Why am I getting this error? What can I do to fix this problem? This code
works fine for smaller and larger documents. Any relevant links to
OutOfMemoryException handling would also be valuable.

Thanks,
Jason

string HTML = Utility.RetrieveContentFromFile ("c:/brakes.htm");
HTML = Regex.Replace(HTML,
"<html>|<body>|<head>|</html>|</head>|</body>|<title>.*</title>", "",
RegexOptions.IgnoreCase);

// the first DIV must be stripped of its "page-break-before" text.
Regex myReg = new Regex("(<DIV.*?STYLE=\".*?)(page-break-before:
always;)(.*?\" *?>)", RegexOptions.IgnoreCase);

// this is the line of code that will raise the error.
HTML = myReg.Replace (HTML, "$1$3", 1);

Console.WriteLine("we got here");
