when i call my XMLModel and try to getXML, i vaing a problem on browser console :

Uncaught TypeError: Failed to execute 'serializeToString' on 'XMLSerializer': parameter 1 is not of type 'Node'

But if, i setXML directly in code, the error doen'st happen

This is my controller,

var oModel = new sap.ui.model.xml.XMLModel();
    oModel.loadData("model/questionario.xml");
    var view = this.getView();  
    view.setModel(oModel);
    var oData = oModel.getXML();
    console.log(oData);

    //This is what i expect to do with the return

        var oData = oModel.getProperty("/pergunta/texto");
        var label_01 = view.byId("lbl_01");
        label_01.setText(oData);



},

And this is my xml Model

<questionario>
<pergunta>
    <id>A</id>
    <texto>Qual o número do seu CPF?</texto>
    <resposta>AAAA</resposta>
</pergunta> 

Thanks for all helps
