Unable to parse value from xml for libgdx code

Question

I am trying to parse data from an xml file into my libgdx game. My xml file is as follows:

<?xml version="1.0" encoding="utf-8"?>
<levels currentLevel = "1">
    <Level1 speed="1" direction="1" lineAngle="14" />
    <Level2 speed="1" direction="1" lineAngle="14" />
    <Level3 speed="1" direction="1" lineAngle="14" />
</levels>

And the code that I call in the show method to take values ​​from xml:

XmlReader xml = new XmlReader();
    try {
        XmlReader.Element element = xml.parse(Gdx.files.internal("levels.xml"));
        XmlReader.Element root = element.getChildByName("levels");
        currentLevel = root.getInt("currentLevel");
        XmlReader.Element level = root.getChildByName("Level1");
        lineAngle = level.getInt("lineAngle");
        speed = level.getFloat("speed");
        direction = level.getInt("direction");
    }catch (Exception e){} 

But I can not get any value from xml. For example, I expect lineAngle to be 14, but it is 0. Could you explain to me why this is so? And any solution would be great. Thank.

When you parse the file into an element, you are already at the root of your XML. This works for me:

XmlReader xml = new XmlReader();
    try {
        // Element is the root element of your document, i.e. <levels>
        XmlReader.Element element = xml.parse(Gdx.files.internal("D:\\someFolder\\android\\assets\\levels.xml"));
        currentLevel = element.getInt("currentLevel");
        XmlReader.Element level = element.getChildByName("Level1");
        lineAngle = level.getInt("lineAngle");
        speed = level.getFloat("speed");
        direction = level.getInt("direction");
    } catch (Exception e) {
    }

I also had to give the full path to levels.xml, for example: "D: \ someFolder \ android \ assets \ levels.xml"
