I would start by assigning the input xml to an XML Dom Document, for example:

Dom.Document doc = new Dom.Document();
doc.load(xml);

Then, you can access its attributes like this:

Dom.XMLNode layout = doc.getRootElement();
Dom.XmlNode[] layoutSections = layout.getChildElements();

Once you have access to the layout sections, you can loop through them and access specific child elements with:

String label = layoutSection.getChildElement('label', null).getText();

Note that a layoutSection is of type XmlNode which means you can keep going through its child elements and access its values.
