Question

I am working with sharePoint Lists webservice, in order to load a dropdown in search page I need to extract all the “ows_Country” name from XML, returend in XMLNode in the Format of :

<rs:data ItemCount="1" xmlns:rs="urn:schemas-microsoft-com:rowset">
   <z:row ows_Title="Nike"    ows_ID="1" ows_Country="Spain"  xmlns:z="#RowsetSchema" /> 
   <z:row ows_Title="Addidas" ows_ID="4" ows_Country="Brazil" xmlns:z="#RowsetSchema" />
   <z:row ows_Title="Puma"    ows_ID="5" ows_Country="Spain"  xmlns:z="#RowsetSchema" />
</rs:data>

I need to use LINQ to get the distinct “ows_Country” from the XMLNode, Kindly help is probably my first experience with LINQ as well as XML.

Answer 1

XNamespace rs = "urn:schemas-microsoft-com:rowset";
XNamespace z = "#RowsetSchema";

XDocument doc = XDocument.Load(...);

var result = doc.Element(rs + "data")
                .Elements(z + "row")
                .Select(e => (string)e.Attribute("ows_Country"))
                .Distinct()
                .ToList();
