In the XmlDigester class you would have to change the following 2 functions...
public int Compare(Object x, Object y)
XmlAttribute lhs = (XmlAttribute)x;
XmlAttribute rhs = (XmlAttribute)y;
string ls = lhs.NamespaceURI;
string rs = rhs.NamespaceURI;
if ((ls == rs) || (ls.Equals(rs) && ls != null && rs != null))
ls = lhs.LocalName;
rs = rhs.LocalName;
if (ls == null)
return -1;
if (rs == null)
return 1;
byte[] larr = Encoding.UTF8.GetBytes(ls);
byte[] rarr = Encoding.UTF8.GetBytes(rs);
int len = Math.Min(larr.Length, rarr.Length);
for (int i = 0; i < len; i++)
int li = (int)(larr[i] & 0xFF);
int ri = (int)(rarr[i] & 0xFF);
int d = li - ri;
if (d != 0)
return d;
return larr.Length - rarr.Length;
private void Serialize(string s, Stream outStream)
byte[] bytes = Encoding.UTF8.GetBytes(s);
int len = bytes.Length;
Serialize((byte)(len >> 8), outStream);
Serialize((byte)(len), outStream);
Serialize(bytes, outStream);
That should do the trick.
