使用linq c＃在单个节点上返回多个具有相同名称的xml子元素＃

Question

I have the following XML and want to return all "schools" children but I only get the first one. (jeffersion/08.36) I looked high and low and banged my head. What am I missing?

<users>
  <user>
    <role>janitor</role>
    <schools>
      <school_name>jefferson</school_name>
      <keycode>80.36</keycode>
      <school_name>mainline</school_name>
      <keycode>64.36</keycode>
      <school_name>south side</school_name>
      <keycode>31</keycode>
    </schools>
  </user>
</users>

This is only returning the first record.

var results= from schools in myXmlDoc.Descendants("schools")
                   select new 
                   {
                       SchoolName = schools.Element("school_name").Value,
                       KeyCode = schools.Element("keycode").Value
                   };

I've also tried:

var results= (from schools in myXmlDoc.Descendants("schools")
                   select new 
                   {
                       SchoolName = schools.Element("school_name").Value,
                       KeyCode = schools.Element("keycode").Value
                   }.ToList();

This gets the values BUT only for the first school:

var schools = (from c in xml.Descendants("user")
                      select new
                      {
                          Name = c.Element("role").Value,
                          Fields = c.Elements("schools")
                              .Select(f => new
                              {
                                  SchoolName = f.Element("school_name").Value,
                                  Keycode = f.Element("keycode").Value
                              }).ToArray()
                      }).ToList();

Answer 1

This may be helpful:

var result = from c in XElement.Load("Student.xml").Elements("schools") select c ;

// Execute the query foreach (var students in result ) { //do something }

Answer 2

You only have one <schools> element in your source, which is why only one entry is being returned. The XML isn't particularly nicely structured - it would be good to have a <school> element containing each school_name/keycode pair. But assuming you have to live with it, the following should work:

var results= from school in myXmlDoc.Descendants("school_name")
               select new 
               {
                   SchoolName = school.Value,
                   KeyCode = school.ElementsAfterSelf("keycode").First().Value
               };
