Can you please explain what happens in this part of the code, it goes through the xml file, I can not figure out
value_dict = {}
for node in elements:
for child in node.childNodes:
if child.nodeType == 1:
if child.tagName == 'Value':
if child.firstChild.nodeType == 3:
value = float(child.firstChild.data.replace(',', '.'))
if child.tagName == 'CharCode':
if child.firstChild.nodeType == 3:
char_code = child.firstChild.data
value_dict[char_code] = value
return value_dict
