@darkom: That's pretty much what linearize_tables does currently

 def linearize(self, root):
        for x in XPath('//h:table|//h:td|//h:tr|//h:th|//h:caption|'
                '//h:tbody|//h:tfoot|//h:thead|//h:colgroup|//h:col')(root):
            x.tag = XHTML('div')
            for attr in ('style', 'font', 'valign',
                         'colspan', 'width', 'height',
                         'rowspan', 'summary', 'align',
                         'cellspacing', 'cellpadding',
                         'frames', 'rules', 'border'):
                if attr in x.attrib:
                    del x.attrib[attr]
