parsing

I have a string input that i do not know whether or not is valid xml.

I think the simplest aprroach is to wrap

new XmlDocument().LoadXml(strINPUT);

In a try/catch.

The problem im facing is, sometimes strINPUT is an html file, if the header of this file contains

<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"">
<html xml:lang=""en-GB"" xmlns=""http://www.w3.org/1999/xhtml"" lang=""en-GB"">

...like many do, it actually tries to make a connection to the w3.org url, which i really dont want it doing.

Anyone know if its possible to just parse the string without trying to be clever and checking external urls? Failing that is there an alternative to xmldocument?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
