[OSM-dev] api update question

[Rob]

i'm trying to update a node from my project (C#)
when i do the web request, the GetResponse returns with "The remote server
returned an error: (417) Expectation Failed."

do i need to change the content type ? or do i have to include
action='modify' in the node ?


            string strXml = "<?xml version='1.0' encoding='UTF-8'?><osm
version='0.5' generator='OSMTAGEDITOR'><node id='30226967' lat='50.8489498'
lon='5.6878935' user='rubke' timestamp='2008-01-20T14:56:52Z'><tag
k='amenity' v='place_of_worship' /><tag k='denomination'
v='christian/catholic' /><tag k='name' v='St-Servaasbasiliek' /><tag
k='religion' v='christian' /></node></osm>";

            HttpWebRequest HttpWRequest =
(HttpWebRequest)WebRequest.Create("
http://api.openstreetmap.org/api/0.5/node/30226967");
            HttpWRequest.PreAuthenticate = true;
            HttpWRequest.Credentials = new NetworkCredential("xxxx",
"xxxx");
            HttpWRequest.Method = "PUT";
            HttpWRequest.ContentLength = strXml.Length;
            HttpWRequest.ContentType = "text/plain";
            using (StreamWriter writer = new StreamWriter(
HttpWRequest.GetRequestStream()))
            {
                writer.WriteLine(strXml);
            }
            WebResponse response = HttpWRequest.GetResponse();

            using (StreamReader reader = new StreamReader(
response.GetResponseStream()))
            {
                while (reader.Peek() != -1)
                {
                    Console.WriteLine(reader.ReadLine());
                }
            }
