Getting the root element of xml file in linq

I am using linq. Here is my document structure:

<t totalWord="2" creationDate="15.01.2016 02:33:37" ver="1">
    <k kel_id="1000">
        <kel>7</kel>
        <kel_gs>0</kel_gs>
        <kel_bs>0</kel_bs>
        <km>Ron/INT-0014</km>
        <kel_za>10.01.2016 02:28:05</kel_za>
        <k_det kel_nit="12" kel_res="4" KelSID="1" >
            <kel_ac>ac7</kel_ac>
        </k_det>
    </k>
    <k kel_id="1001">
        <kel>whitte down</kel>
        <kel_gs>0</kel_gs>
        <kel_bs>0</kel_bs>
        <km>Ron/INT-0014</km>
        <kel_za>15.01.2016 02:33:37</kel_za>
        <k_det kel_nit="12" kel_res="4" KelSID="1">
            <kel_ac>to gradually make something smaller by making it by taking parts away</kel_ac>
            <kel_kc>cut down</kel_kc>
            <kel_oc>The final key to success is to turn your interviewer into a champion: someone who is willing to go to bat for you when the hiring committee meets to whittle down the list.</kel_oc>
            <kel_trac >adım adım parçalamak</kel_trac>
        </k_det>
    </k>
</t>

This is a dictionary. t is root. k is word. When a new word arrives, totalword attribute and creationDate shall update accordingly. I have to get t node, get its attribute and save it. I have written the code above: 

XDocument xdoc = XDocument.Load(fileName);
XElement rootElement = xdoc.Root;
XElement kokNode = rootElement.Element("t");
XAttribute toplamSayi = kokNode.Attribute("totalWord");

kokNode comes null. How can I solve it? Thanks in advance.

"totalWord" is an attribute of the root element which is t, not an attribute of k. So simply get the attribute from the root element like this:

XDocument xdoc = XDocument.Load(fileName);

XElement rootElement = xdoc.Root;

XAttribute toplamSayi = rootElement.Attribute("totalWord");

xdoc.Root will return the root element, which is your t element in this case.

rootElement.Element("t") will therefore return null as t has no child t element.

Either use xdoc.Root or xdoc.Element("t"), i.e.:

var tomplamSayi = xdoc.Root.Attribute("totalWord")

or:

var tomplamSayi = xdoc.Element("t").Attribute("totalWord")

try this :

string totalword;
foreach (XElement x in xdoc.Descendants("t")){
   totalword= x.Attribute("totalword").Value.ToString().Trim(); // Get the totalword attribute's value
}
