xml ns0: префикс не может заставить предыдущие решения работать

#python #xml #elementtree

#python #xml #elementtree

Вопрос:

я знаю, что есть несколько вопросов, на которые уже даны ответы по этой теме, но по какой-то причине я не могу заставить его работать, когда я читаю файл.

это код, который у меня есть 

 import xml.etree.ElementTree as etree
import copy
etree.register_namespace("","http://www.w3.org/2001/XMLSchema")
etree.register_namespace("","http://www.w3.org/2001/XMLSchema-instance")
#Estract the search set thats necesary
tree=etree.ElementTree()
tree.parse('Selection Sets.xml')
root = tree.getroot()
#QTO with one set name and properties as needed, same properties will be applied to the new elements
itree=etree.ElementTree()
itree.parse('New QTO one set.xml')
iroot=itree.getroot()
print (etree.tostring(iroot))
#----Extract the names to be used in the new sets
catcher=[]
temp=tree.findall('selectionsets/selectionset')
for child in temp:
    catcher.append(str(child.get("name")))
# print (catcher)
#----create new elements inside the QTO xml
'''itemp=iroot.findall("Takeoff/Catalog")
for isets in itemp:
    for icatch in catcher:
        col = copy.deepcopy(isets)
        col.set('Name','%s'%(icatch))
        iroot.find('Takeoff/Catalog/Item').append(col)'''
print (catcher[0])
otree = etree.ElementTree(iroot)
otree.write('Set QTO.xml')

это исходная структура файла xml

1. чего вы пытаетесь достичь, а что не работает?

2. я пытаюсь добавить новые «Элементы», используя элементы из другого xml. но перед этим мне нужно убрать ns0: с пути.

Ответ №1:

Теперь я понимаю проблему, у вас есть нежелательные префиксы ns0 в вашем выводе. Чтобы избежать их, вам может потребоваться зарегистрировать все пространства имен с соответствующими префиксами:

 etree.register_namespace("xs","http://www.w3.org/2001/XMLSchema")
etree.register_namespace("xsi","http://www.w3.org/2001/XMLSchema-instance")
etree.register_namespace("","http://download.autodesk.com/us/navisworks/schemas/nw-TakeoffCatalog-10.0.xsd")
