I'm having a problem using lxml.etree to make a treebuilding parser that validates; I have test code where invalid xml

I managed to overcome this problem by utilizing the non-targeted parser with returns an _ElementTree object. I can then
convert to tuple tree using code like this
class TT:
def __init__(self):
pass
def __call__(self,tree):
if not tree: return
return self.maketuple(next(tree.iter()))
def maketuple(self,e):
return (e.tag,e.attrib or None,self.content(e),e.sourceline)
def content(self,e):
t = e.text
kids = e.getchildren()
if len(kids)==0 and t is None:
return t
else:
r = [].append
if t is not None: r(t)
for c in kids:
r(self.maketuple(c))
t = c.tail
if t is not None:
r(t)
return r.__self__
