我有一个XML结构如下：

<questions>
<question id="q1">
  <number>1</number>
  <text>some text11</text>
  <answers>
     <answer>
      <v>some text11</v>
    </answer>
    <answer>
      <v>some text11</v>
    </answer>
  </answers>
</question>
<question id="q2">
  <number>2</number>
  <text>some text2</text>

<answers>
    <answer>
      <v>some text22</v>
    </answer>
    <answer>
      <v>some text22</v>
    </answer>
  </answers>
</question>
<question id="q3">
  <number>3</number>
  <text>some text3</text>
  <answers>
    <answer>
      <v>some text33</v>
    </answer>
    <answer>
      <v>some text33</v>
    </answer>
    <answer>
      <v>some text33</v>
      <addDescription>some text333</addDescription>
      <textBox/>
    </answer>
  </answers>
</question>
</questions>

……我有以下课程：

public class Question
{
    public string text { get; set; }
    public IList<Anwser> anwsers = new List<Anwser>();
}

public class Anwser
{
    public string content { get; set; }
}

…我已经构建了一个以下(错误的)Linq查询：

List<Question> questions = (from xml in xdoc.Element("survey").Elements("questions").Elements("question")
                                    select new Question()
                                               {
                                                   text = xml.Element("text").Value,anwsers =
                                                       (from anwsers in
                                                            xdoc.Element("survey").Elements("questions").Elements("question").Elements(
                                                            "answers").Elements(
                                                            "answer")
                                                        select new Anwser()
                                                                   {
                                                                       content = anwsers.Element("v").Value
                                                                   }

                                                       ).ToList()
                                            }).ToList();

当然,这样每次所有问题的所有问题都会添加到每个列表中.
怎么解决这个？我可以想象这很简单,但我不知道:)

先感谢您！
