我知道有几个问题已经回答了这个主题，但由于某种原因，我无法在阅读文件时使其工作。
这是我的代码
~/.vimrc这是原始的xml文件结构
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')
到目前为止的部分结果
<?xml version="1.0" encoding="utf-8"?>

答案 0 :(得分：0)
我现在理解了这个问题，你的输出中有不需要的ns0前缀。为了避免它们，您可能需要使用相应的前缀注册所有名称空间：
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")
