Prevent DTD download when parsing XML

Question

When using XmlDocument.Load , I am finding that if the document refers to a DTD, a connection is made to the provided URI. Is there any way to prevent this from happening?

Answer 1

Try something like this:

XmlDocument doc = new XmlDocument();
using (StringReader sr = new StringReader(xml))
  using (XmlReader reader = XmlReader.Create(sr, new XmlReaderSettings()))
  {
     doc.Load(reader);
  }

The thing to note here is that XmlReaderSettings has the ProhibitDtd property set to true by default.
