Parsing String from XML to C# [duplicate]

I have written the following code in XML and I want to parse it to C# and show it in a ListBox.

This is the code from the XML file:

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE root [
  <!ELEMENT root (Persoane*)>
  <!ELEMENT Persoane (nume)>
  <!ELEMENT IsMale (#PCDATA)>
  <!ELEMENT Varsta (#PCDATA)>
  <!ELEMENT PersoanaPlacuta (#PCDATA)>
 ]>
<root>
  <Persoane nume ="Bob">
    <IsMale>true</IsMale>
    <Varsta>30</Varsta>
    <PersoanaPlacuta>"Iulia"</PersoanaPlacuta>
  </Persoane>
</root>

and this is the code in C#:

private void LoadPersoane()
    {
        XmlDocument doc = new XmlDocument();
        XDocument persoanaPlacuta = new XDocument();

        doc.Load("Baza_de_cunostinte.xml");

        foreach (XmlNode node in doc.DocumentElement) 
        {
            string nume = node.Attributes[0].Value;
            int varsta = int.Parse(node["Varsta"].InnerText);
            bool isMale = bool.Parse(node["IsMale"].InnerText);
            persoanaPlacuta = XDocument.Parse(node["PersoanaPlacuta"].InnerText);

            listBox.Items.Add(new Persoane(nume, varsta, isMale, persoanaPlacuta));
        }
    }

Everything works fine, except the field "PersoanaPlacuta". I don't know how to parse it to C#... I tried, but with no luck...
