How to set ProhibitDtd to false?

When I'm trying to use an xsl file on an xml output of my program, I get the following error:

Exception Details: System.Xml.XmlException: For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method.

It's pretty clear, but the problem is... I do not have an xmlReader anywhere. All I do is get an XmlDataDocument, and then process it with XslCompiledTransform. Where is the XmlReader whose settings I should change?  Is it created behind the scenes by one of these two classes?  How do I access it?

Check your !DOCTYPE declaration node:

Tornado,
I don't see any !DOCTYPE in my XML. This is the only line on top of the XML file that my program generates:
<?xml version="1.0" encoding="utf-8"?>

The rest of it is xml data itself (customers with their info).

Any ideas? Maybe I don't understand the whole !DOCTYPE thing?  The article you sent is a little bit unclear regarding what actually solved the problem.

Max,

Can you please post a line that causes the error?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Apologies for the delay, there's been a break in our work.  It seems that the line, which causes error is located in XSL document, created by a designer, and the xsl he made is proper and definitely works (it's been tested by him on other xsl processors). All I have to do, is somehow remove that Dtd Prohibition in my program.

This should be helpful, look for "Performing the Transformation" and "Whitespace Handling" sections:

Try this:

XmlDocument doc = new XmlDocument();
doc.XmlResolver = null;
doc.Load(yourdocument);
