感谢您花时间使用这个。 我有一个xml文件，其中包含一个名为selectionset的元素。我的想法是采用该元素并修改一些子元素属性和尾部，这部分我已经完成了。 我得到的阴暗的东西是为什么当我尝试将新的子元素添加到原始（称为选择集）时，它只推动列表中的最后一个inplist
import xml.etree.ElementTree as etree
from xml.etree.ElementTree import *
from xml.etree.ElementTree import ElementTree
tree=ElementTree()
tree.parse('STRUCTURAL.xml')
root = tree.getroot()
col=tree.find('selectionsets/selectionset')
#find the value needed
val=tree.findtext('selectionsets/selectionset/findspec/conditions/condition/value/data')
setname=col.attrib['name']
listnames=val + " 6"
inplist=["D","E","F","G","H"]
entry=3
catcher=[]
ss=root.find('selectionsets')
outxml=ss
for i in range(len(inplist)):
str(val)
col.set('name',(setname +" "+ inplist[i]))
col.find('findspec/conditions/condition/value/data').text=str(inplist[i]+val[1:3])
#print (etree.tostring(col)) #everything working well til this point
timper=col.find('selectionset')
root[0].append(col)
# new=etree.SubElement(outxml,timper)
#you need to create a tree with element tree before creating the xml file
itree=etree.ElementTree(outxml)
itree.write('Selection Sets.xml')
print (etree.tostring(outxml))
# print (Test_file.selectionset())
#Initial xml

答案 0 :(得分：0)
这是我能够放在一起的东西，看起来它会做你正在寻找的东西。以下是主要区别：（1）这将迭代多个选择集项（如果最终有多个），（2）在修改值之前创建元素的深层复制（我认为你总是修改原始值） “col”），（3）它将新的选择集附加到selectionsets标签而不是根。
import xml.etree.ElementTree as etree
import copy
tree=etree.ElementTree()
tree.parse('test.xml')
root = tree.getroot()
inplist=["D","E","F","G","H"]
for selectionset in tree.findall('selectionsets/selectionset'):
for i in inplist:
col = copy.deepcopy(selectionset)
col.set('name', '%s %s' % (col.attrib['name'], i))
data = col.find('findspec/conditions/condition/value/data')
data.text = '%s%s' % (i, data.text[1:3])
root.find('selectionsets').append(col)
itree = etree.ElementTree(root)
itree.write('Selection Sets.xml')
