Hello all,
I am having some trouble with my recursive function, I have written a few
for this project and have not seen this behaviour until now.
It is looping over certain xml elements in a file and looking for the
correct one based on your selected QTreeWidgetItem which is working fine up
to a certain recursion level, I have jumped into the debugger a few times
and cannot wrap my head around whats going on.
My issue is when you hit a deeper recursion level as I hit the correct item
(if item == treeviewitem[0]) it jumps in and gets the correct XML element
which is exactly what I need EXCEPT when it returns it returns to the very
bottom gatherXMLElementInfo line and repeats the process even though the
process is complete and I dont need it to anymore and is causing program
errors.
I was under the assumption that once the function is complete and something
is returned the program should finish iterating through the code, it has
been this way so far so I am wondering if I am missing something??
Function is below :)
Thanks for the help!
def gatherXMLElementInfo(treeViewItems, root):
#print root.attrib
# Iterate backwards through the object list
for item in reversed(treeViewItems):
# If the current item is the last item in the list
if item == treeViewItems[0]:
#print "Item is", item
# We need to iterate through the parent element
children i.e. the list that our element is hiding in
if not item in self.elemsToIgnore:
if root.getchildren():
for elem in root.getchildren():
elemAttributes = elem.attrib
correctElement =
[elemAttributes.get(i) for i in elemAttributes if elemAttributes.get(i) == item]
if correctElement:
print correctElement[0]
break
return
else:
return
else:
if item in self.elemsToIgnore:
print "IGNORE", item
xmlElem = root.findall(item)[0]
else:
################# Fix this loop! #############
# Need to get the element from the name of the
qt displayed item
for child in root.getchildren():
#print child, root
elemAttributes = child.attrib
correctElement = [elemAttributes.get(i)
for i in elemAttributes if elemAttributes.get(i) == item]
if correctElement:
print "FOUNDDDDDD IT", child
xmlElem = child
break
listMinusOne = [i for i in treeViewItems if not i ==
item]
print " XML ELm", xmlElem
gatherXMLElementInfo(listMinusOne, xmlElem)
print "IGNORE", item
xmlElem = root.findall(item)[0]
else:
################# Fix this loop! #############
# Need to get the element from the name of the qt displayed item
for child in root.getchildren():
#print child, root
elemAttributes = child.attrib
correctElement = [elemAttributes.get(i) for i in elemAttributes if
elemAttributes.get(i) == item]
if correctElement:
print "FOUNDDDDDD IT", child
xmlElem = child
break
listMinusOne = [i for i in treeViewItems if not i == item]
print " XML ELm", xmlElem
gatherXMLElementInfo(listMinusOne, xmlElem)
