Subject: For security reasons DTD is prohibited in this XML document.

Hey Alex,

We're having a problem with the Matrix library which we haven't encountered before now when connecting to one of our Servers.

The XML shown is as follows:

10/6/2015 4:21:01 PM - SEND: <stream:stream xmlns:stream="http://etherx.jabber.org/streams" xmlns="jabber:client" to="wasbt.guestwarehost.com" version="1.0" >
10/6/2015 4:21:02 PM - SEND: </stream:stream>

In between 10/6/2015 4:21:01 PM and 10/6/2015 4:21:02 PM we receive a error from the onError event which upon retrieving the base exception we get the following message:
For security reasons DTD is prohibited in this XML document. To enable DTD processing set the DtdProcessing property on XmlReaderSettings to Parse and pass the settings into XmlReader.Create method.

We are using Matrix Version 1.6.0.3 for .net 4.0.

We presently think that the exception is occurring because the matrix library XML object used for parsing is failing somewhere.

Thanks for your help.

Alex

MatriX is not using XmlReader when parsing the Xml Stream from the server. It has a custom Xml parser.

Its using XmlReader only in 1 place. This is when you use XmppXElement.LoadXml to load a XmlDocument to MatriX objects.
Are you using XmppXElement.LoadXml in your codes?

Or do you use XmlReader somewhere in your codes? And the entry point to this code is a MatriX event? When you don't catch your own exceptions then they will raise in MatriX of course, and MatriX sends them back to you in an OnError event.
