Parsing xml string to an xml document fails if the string begins with <?xml… ?> section

Question

I have an XML file begining like this:

Answer 1

If you only have bytes you could either load the bytes into a stream:

XmlDocument oXML;

using (MemoryStream oStream = new MemoryStream(oBytes))
{
  oXML = new XmlDocument();
  oXML.Load(oStream);
}

Or you could convert the bytes into a string (presuming that you know the encoding) before loading the XML:

string sXml;
XmlDocument oXml;

sXml = Encoding.UTF8.GetString(oBytes);
oXml = new XmlDocument();
oXml.LoadXml(sXml);

I've shown my example as .NET 2.0 compatible, if you're using .NET 3.5 you can use XDocument instead of XmlDocument.

Load the bytes into a stream:

XDocument oXML;

using (MemoryStream oStream = new MemoryStream(oBytes))
using (XmlTextReader oReader = new XmlTextReader(oStream))
{
  oXML = XDocument.Load(oReader);
}

Convert the bytes into a string:

string sXml;
XDocument oXml;

sXml = Encoding.UTF8.GetString(oBytes);
oXml = XDocument.Parse(sXml);
