C# XML Descending order with elements and attributes -


i need find 5 maximum students xml file

my xml file looks this

<professor id="andy"> <floor nb="1">   <data>     <room>101</room>     <nbstudent>33724</nbstudent>   </data>       </floor> </professor >   <professor id="mick"> <floor nb="2">   <data>     <room>102</room>     <nbstudent>33740</nbstudent>   </data>   </floor> </professor >

for code is

var xdoc = xdocument.load("student.xml"); var student=            (from r in xdoc.descendants("data")            orderby int.parse(r.xpathselectelement("nbstudent").value) descending           select new           {            name = r.xpathselectelement("//professor").attribute("id").value + "   ",            room= r.xpathselectelement("room").value + "   ",            nb= r.xpathselectelement("nbstudent").value + "    ",                   })      .take(5); foreach (var r in student)             {                 console.writeline(r.name + r.room+ r.nb);             }

it find 5 value want name return same (even if data after doesn't belong attribute.

i don't know how correct attribute.

another possible option fix problem minimal changes original code :

name = r.xpathselectelement("ancestor::professor[1]").attribute("id").value + "   ",
