Here's one approach.

    from xml.dom.minidom import parse
    doc = parse(file('XML/1.xml'))
    cdata = []
    elements = [doc.documentElement]
    while elements:
        e = elements.pop(0)
        if e.nodeType == doc.TEXT_NODE:
            cdata.append(e.data)
        elif e.nodeType == doc.ELEMENT_NODE:
            elements[:0] = e.childNodes
    print cdata

I bet there are simpler ways, though, based on other XML libraries.
