im trying to read from this http://api.hostip.info/?ip=126.96.36.199
XmlDocument xml = new XmlDocument();
XmlNodeList xnList = xml.SelectNodes("gml:featureMember/Hostip");
foreach (XmlNode xn in xnList)
string Name = xn["countryName"].InnerText;
im getting a weird error
Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.
never seen something like that before...
Best How To :
You need to, first, define mapping of namespace prefix to namespace uri, before you can use the prefix in your xpath. In this case, use
XmlNamespaceManager to define the mapping, then you can simply pass the namespace manager instance as 2nd parameter of
SelectNodes() : :
var nsManager = new XmlNamespaceManager(new NameTable());
//register mapping of prefix to namespace uri
//pass the namespace manager instance as 2nd param of SelectNodes():
XmlNodeList xnList = xml.SelectNodes("HostipLookupResultSet/gml:featureMember/Hostip", nsManager);
There is another problem in your xpath.
gml:featureMember is not the root element of the XML, it is the root's child. So you need to mention the root element before
gml:featureMember as demonstrated above, or alternatively using
descendant-or-self axis like :
//gml:featureMember/Hostip (the latter would be a bit slower though).
