c# - How to find specific data in XML POST Response? -

i'm tasked retrieving specific data xml post response.

here's example of xml reply:

<servicehistoryarray>     <recordid>xd116067*401529</recordid>     <swr>         <v idx="1">7932</v><v idx="2">7932</v><v idx="3">7932</v><v idx="4">7932</v>     </swr>     <comments/>     <mileage>6</mileage>     <operation>         <v idx="1">z7000*wpdip****pre-delivery inspection - base time</v><v idx="2">z911*inc****etch windows</v><v idx="3">b0048*wpbs4****fascia, front bumper - replace 1 piece</v><v idx="4">9997*wpbs4****</v>     </operation>     <closedate>1998-12-30</closedate>     <opendate>1998-10-16</opendate>     <partsamount>         <v idx="1">0.00</v><v idx="2">0.00</v><v idx="3">166.32</v><v idx="4">0.00</v>     </partsamount>     <laboramount>         <v idx="1">64.80</v><v idx="2">3.60</v><v idx="3">140.40</v>     </laboramount>     <warranty>         <s idx="1">&#xfc;96&#xfc;0&#xfd;&#xfd;10232632&#xfc;4h&#xfc;1</s><s idx="2">&#xfc;96&#xfc;0&#xfd;&#xfd;10232632&#xfc;4h&#xfc;1</s><s idx="3">&#xfc;96&#xfc;0&#xfd;&#xfd;10232632&#xfc;4h&#xfc;1</s>     </warranty> </servicehistoryarray>   

i need concatenate of related "v" elements' inner text.

ex:
7392 z700*wdip****pre-delivery inspection - base time 0.00 64.80
7392 z911*inc****etch windows 0.00 3.60
etc...

here's code far:

// string variable store xml post reply    string replystring = webrequestpostdata("http://" + maskedtextbox1.text + ":" + maskedtextbox2.text, payload);       xmldocument replydoc = new xmldocument();  // new xmldocument reply     replydoc.loadxml(replystring);     xmlnodelist list = replydoc.selectnodes("//servicehistoryarray/*");  // xmlnodelist based on child elements of <servicehistoryarray> node.      var nodees = new list<xmlnode>(list.cast<xmlnode>().toarray());      // finds mileage, closedate, , opendate values , displays them on form.     foreach (xmlnode node in nodees)     {         switch (node.name)         {             case "opendate":                 textbox1.text = node.innertext;                 break;             case "closedate":                 textbox2.text = node.innertext;                 break;             case "mileage":                 textbox3.text = node.innertext;                 break;         }     }      // section supposed display concatenated values of <v> elements:     (int = 0; < nodees.count; i++)     {         if (nodees[i].haschildnodes)         {             (int j = 0; j < nodees[i].childnodes.count; j++)             {                 switch (nodees[i].childnodes[j].nodetype)                 {                     case xmlnodetype.text:                         break;                     case xmlnodetype.element:                         switch (nodees[i].childnodes[j].attributes[0].value)                         {                              case "1":                                 console.writeline("1-" + nodees[i].childnodes[j].innertext + " ");                                 break;                             case "2":                                 console.writeline("2-" + nodees[i].childnodes[j].innertext + " ");                                 break;                             case "3":                                 console.writeline("3-" + nodees[i].childnodes[j].innertext + " ");                                 break;                             case "4":                                 console.writeline("4-" + nodees[i].childnodes[j].innertext + " ");                                 break;                         }                         break;                 }             }         }     } 

the concatenated values need displayed in listbox control. additionally, need try , code process not anticipate set number of elements; in case there 4. other instances of post request may return 10 or 2 or whatever.

i realize may or may not impact other users i'm not 1 out there problem...

you can use linq xml:

xdocument xdoc = xdocument.parse(replystring); var query = v in xdoc.descendants("v")             group v (int)v.attribute("idx") g             select string.join(" ", g.select(x => (string)x)); 

this query selects v elements in document , groups them idx atribute value (in order elements appear in document). values of elements in group concatenated string. query contain:

"7932 z7000*wpdip****pre-delivery inspection - base time 0.00 64.80" "7932 z911*inc****etch windows 0.00 3.60" "7932 b0048*wpbs4****fascia, front bumper - replace 1 piece 166.32 140.40" "7932 9997*wpbs4**** 0.00"
