Question

I am trying to get some data from xml file from my C# coding.

How can I get the data of claim node if the following claim-ib-info node does not contain withdrawn node.

If you are not clear about my question, let me know.

I don’t know much about XML and thanks in advance.

<info>
    <claim kind="national" sequence="1">
        <country>UK</country>
        <number>66</number>
        <date>20080602</date>
    </claim>
    <claim-ib-info>
        <received-at>
            <date>20090610</date>
        </received-at>
    </claim-ib-info>


    <claim kind="national" sequence="2">
        <country>US</country>
        <number>125</number>
        <date>20080501</date>
    </claim>
    <claim-ib-info>
        <withdrawn>
            <date>20100721</date>
        </withdrawn>
    </claim-ib-info>


    <claim kind="national" sequence="3">
        <country>TH</country>
        <number>61</number>
        <date>20090316</date>
    </claim>
    <claim-ib-info>
        <received-at>
            <date>20090610</date>
        </received-at>
    </claim-ib-info>


    <claim kind="national" sequence="4">
        <country>MY</country>
        <number>66</number>
        <date>20090209</date>
    </claim>
    <claim-ib-info>
        <withdrawn>
            <date>20101221</date>

Try to learn and use Linq to XML.

var list = from ele in XDocument.Load(@"c:\files.xml").Descendants("claim-ib-info")
                    where ele.Element("withdrawn")!=null
                   select ele.PreviousNode  ;

foreach (var t in list)
{
    Console.WriteLine(t);
}
