Code:
void SaveAll()
{

    XmlDocument xDoc = new XmlDocument();

    string path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
    string vocabulary_path = path + "\\Vocabulary\\Words.xml";

    xDoc.Load(vocabulary_path);
    XmlNode xNode = xDoc.SelectSingleNode("Words");
    xNode.RemoveAll();
    foreach (Word w in words)
    {
        XmlNode xTop = xDoc.CreateElement("Word");
        XmlNode xWord = xDoc.CreateElement("Word");
        XmlNode xExplanation = xDoc.CreateElement("Explanation");
        XmlNode xTranslation = xDoc.CreateElement("Translation");
        XmlNode xExamples = xDoc.CreateElement("Examples");

        xWord.InnerText = w.WordOrPhrase;
        xExplanation.InnerText = w.Explanation;
        xTranslation.InnerText = w.Translation;
        xExamples.InnerText = w.Examples;
        xTop.AppendChild(xWord);

Napravio sam za sebe jednu aplikaciju u C# koju koristim za ucenje engleskog. E sad, prebacio sam se na Linux i pokusao sam da tu aplikaciju run-ujem preko Mono-a, medjutim ne radi mi bas najbolje pa sam resio da je napravim u Pythonu (ucim Python, spremam se za fax). Uradio sam oko 50% posla - napravio sam GUI i nekoliko metoda, ali zapeo sam kod loadovanja/save-ovanja elemenata iz liste u/iz XML, uopste ne znam odakle da krenem. Mislim da treba koristiti klasu ElementTree, ali ni u to nisam siguran. Ako moze pomoc, ili neki link... Hvala unapred

Finalno resenje:

Code:
    def save_all(self):

        path = os.path.expanduser('~/Desktop')
        vocabulary = os.path.join(path, 'Vocabulary', 'Words.xml')

        tree = ET.ElementTree(file=vocabulary)

        for xNode in tree.getroot().findall('Word'):
            tree.getroot().remove(xNode)

        for w in self.words:
            xTop = ET.Element('Word')
            xWord = ET.Element('Word')
            xExplanation = ET.Element('Explanation')
            xTranslation = ET.Element('Translation')
            xExamples = ET.Element('Examples')

            xWord.text = w.wordorphrase
            xExplanation.text = w.explanation
            xTranslation.text = w.translation
            xExamples.text = w.example

            xTop.append(xWord)
            xTop.append(xExplanation)
            xTop.append(xTranslation)
            xTop.append(xExamples)

            tree.getroot().append(xTop)

        tree.write(vocabulary)
