Check wellformedness of XML

Is there a way (without a schema or dtd) to check that my XML (currently
held in a string variable) is wellformed? I've looked on google and in the
help files and couldn't find anything about this.
Thanks!

Hi Tom,

You can read the XML with XmlTextReader. To quote MSDN:

"The XmlTextReader class is an implementation of XmlReader, and provides a
fast, performant parser. It enforces the rules that XML must be well-formed.
It is neither a validating nor a non-validating parser since it does not
have DTD or schema information. It can read text in blocks, or read
characters from a stream."

And an example from another MSDN article to which I have added code to read
the whole contents of the XML stream.

string str = "<ROOT>AQID</ROOT>";
XmlTextReader r = new XmlTextReader(new StringReader(str));
try
{
while (r.Read())
{
}
}
finally
{
r.Close();
}
 
Great, thanks!
