Is there any option to have a less strict html validator?

sgmoore · September 2012

I am trying to do some queries on a table which has a column which contains a html style email message, but when I call Util.RawHtml on the column it gives the error Cannot parse custom HTML: '

The following samples give an illustration of a good and bad example which seems to be caused by the presence of <meta> and <br> tags without the corresponding </meta> and </br> tags.


var html = @"
<html>
<head>
<meta http-equiv=""Content-Type"" content=""text/html; charset=iso-8859-1""></meta>
</head>

<body>
<b>Hello</b><br></br>world.
</body>
</html>
";

Util.RawHtml(html).Dump(); // Works fine

var html2 = @"
<html>
<head>
<meta http-equiv=""Content-Type"" content=""text/html; charset=iso-8859-1""> 
</head>

<body>
<b>Hello</b><br>world.
</body>
</html>
";
Util.RawHtml(html2).Dump(); // Throws error Cannot parse custom HTML:

Is there anything that can be done to display such messages?

Thanks
Stephen

PS
Apologies for the formatting, hopefully this will be readable.

Util.RawHtml emits an XElement which feeds into a larger XDocument when dumped (along with everything else that you Dump). This is why it must be valid XML - otherwise the XElement constructor will throw an exception.

LINQPad's Dump method is implemented mostly as a LINQ query, which is why it relies on LINQ to XML.

Thanks.

I decide to forget about trying to display to message but instead display a link which opens a webbrowser ie

(from msg in messages
select new { msg.DateTime, msg.Subject ,
Link = (new Hyperlinq(
QueryLanguage.Expression,
String.Format("new System.Windows.Forms.WebBrowser()" +
" {{ DocumentText = System.Uri.UnescapeDataString( \"{0}\") }} "
, System.Uri.EscapeDataString(msg.BodyHtmlText)) ,
"Click here to view message"))
}).Dump();

I also needed to add System.Windows.Forms.dll to the defaults
