XmlRpcParser can get into an infinite loop in MoveToEndElement #110

Open GoogleCodeExporter opened 9 years ago

What steps will reproduce the problem?
1. Call a server implementation with:
<?xml 
version="1.0"?><methodCall><methodName>method_name</methodName></methodCall>
Note, there are no spaces between tags.

When MoveToEndElement is called at the end of the ParseRequest method, the 
rdr.Depth and mcDepth are both 0. Because neither of the if conditions are met 
in the while loop, it loops continuously.

To fix this I wrapped the rdr.Read() call in an if:
if (!rdr.Read()) break;
I also added a new test at the start of the MoveToEndElement method:
if (rdr.Depth == mcDepth && rdr.NodeType == XmlNodeType.None)
    return true;
