You should start by writing down the XML structure that you want to build

I need an xml file structure as below:

This is a very small part of the actual output I need.
Dicts which I am creating looks like =
{'chipsim':{'name':sh2a,'size':32,'bus_width':'4','PIF':{'name':'PIF','offseet':'4','name_of_peer_string':'new_string'},'interrupt_tree':{'tree_level_0':{'tree_level_1':{.....}}}}}
Now, that really makes it clear what you want. You can try this:
import xml.etree.ElementTree as ET
def to_xml_elements(d):
elements = []
# run through all items in the dict
for name, value in d.items():
element = ET.Element(name)
if isinstance(value, dict):
# this is a sub-dict => inject its content recursively
element[:] = to_xml_elements(value)
else:
# normal value => insert as string value
value_element = ET.Element(key)
value_element.text = str(value)
element.append(value_element)
# return list of elements that were created from the dict
return elements
I guess ElementTree is the best way to go about it. But have not found a
good reference on how to use it.
There's lots of info on the web. Start at the effbot site:
