One follow-up, I see that html tags are being stripped; to briefly
illustrate, the following is pasted in:
#########
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>News from The Museum: Kinofest NYC 2013</title>
<meta name="robots" content="noindex,nofollow">
<style type="text/css">
ul {
margin-top: 0px;
margin-bottom: 0px;
}
#########
and the following is received (if you dig ...)
#########
News from The Museum: Kinofest NYC 2013
<style type="text/css">
ul {
margin-top: 0px;
margin-bottom: 0px;
}
