Hi ,
Iam very much new to python. Iam trying to construct a xml dom tree
using the builtin HTMLParser class (on data event callbacks). Iam
maintaining the childs as a list of elements and whenver the sax
parser encounters a tag i push it to a local stack, my basic logic is
below.
**************
def handle_starttag(self, tag, attrs):
curElement=HTMLElement(tag.lower(),
attrs); <------ (1)
if(self.elementRoot == None):
self.elementRoot = curElement
else:
self.elementStack[-1].childs.append(curElement)
<------ (2)
self.elementStack.append(curElement)
**************
here is the definintion of htmlelement
class HTMLElement:
tag=None
attrs={}
data=''
childs=[]
the issue is the though new elements are pushed in the stack (1),
whenever i append the child to the stack top all other elements in the
stack is getting affected, i assume the same reference is used but is
there a way to overcome this ?
