c# - Read XML by its tag name -

-

i have xml services respond , here's sample :

<?xml version="1.0"?> <s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">     <s:body>         <ns4:loginresponse xmlns="http://www.website.com/inctypes" xmlns:ns2="http://yyy.website.com/security" xmlns:ns3="http://yyy.incognito.com/service" xmlns:ns4="http:/yyy.website.com/wsdl/security">             <ns2:errorcode>                 <haserror>true</haserror>                 <status>status_error</status>                 <problemcode>-1</problemcode>                 <problemmessage>service provider         not known</problemmessage>                 <extendedinformation>service provider         not known</extendedinformation>             </ns2:errorcode>         </ns4:loginresponse>     </s:body> </s:envelope>

i want value of tag

                    <haserror>true</haserror>                     <status>status_error</status>                     <problemcode>-1</problemcode>                     <problemmessage>service provider

and here's c# code:

 foreach (xmlnode node in loginresp.documentelement)             {                 if (node.firstchild.firstchild.haschildnodes == true)                 {                     foreach (xmlnode y in node.firstchild.firstchild.childnodes)                     {                         haserror = y.innerxml;                         status= y.innerxml;                     }                 }             }

but gives me either haserror , errocode same value of <ns2:errorcode> <extendedinformation>service provider not known</extendedinformation> how <haserror>true</haserror> <status>status_error</status> value ?

you can try use linq-to-xml suggested @nomad17. makes not trivial is, xml has namespaces. hence need define xnamespaces used match element names :

xnamespace ns = "http://www.website.com/inctypes"; xnamespace ns2 = "http://yyy.website.com/security"; var loginresp = xdocument.parse("xml string here"); //get <ns2:errorcode> element var errorcode = loginresp.descendants(ns2 + "errorcode").firstordefault(); if(errorcode != null) {     //get <haserror> element under <ns2:errorcode>     var haserror = (string)errorcode.element(ns + "haserror");     //get <status> element under <ns2:errorcode>     var status = (string)errorcode.element(ns + "status"); }
