Here is an useful function I have written:

def getText(node, recursive = False):
    """
    Get all the text associated with this node.
    With recursive == True, all text from child nodes is retrieved
    """
    L = ['']
    for n in node.childNodes:
        if n.nodeType in (dom.Node.TEXT_NODE,
dom.Node.CDATA_SECTION_NODE):
            L.append(n.data)
        else:
            if not recursive:
                return None
            L.append( get_text(n) )
                
    return ''.join(L)



>>> print getText(element[0])
