在这里,我想将csv列表传递到我的python代码中,以仅检索与csv列表中匹配的Childone值。正确的方法是什么?
import xml.etree.ElementTree as ET
import csv
tree = ET.parse("C:/Users/thisuser/Desktop/stack.xml")
root = tree.getroot()
with open('C:/Users/thisuser/Desktop/stack.csv', 'rb') as f:
reader = csv.reader(f)
your_list = list(reader)
for ticket in root.findall('.//Parent'):
Childone = ticket.find('.//Childone').text
for Childone in your_list:
for ticket2 in ticket.findall('.//ParentTwo'):
Childtwo = ticket2.find('.//Childtwo').text
print "Childone={Childone}, Childtwo={Childtwo}".format(Childone=Childone, Childtwo=Childtwo)
所需结果
ChildOne=2 ChildTwo=c
ChildOne=2 ChildTwo=d
ChildOne=3 ChildTwo=c
ChildOne=3 ChildTwo=e
当前结果
Childone=['2'], Childtwo=a
Childone=['2'], Childtwo=b
Childone=['3'], Childtwo=a
Childone=['3'], Childtwo=b
Childone=['2'], Childtwo=c
Childone=['2'], Childtwo=d
Childone=['3'], Childtwo=c
Childone=['3'], Childtwo=d
Childone=['2'], Childtwo=c
Childone=['2'], Childtwo=e
Childone=['3'], Childtwo=c
Childone=['3'], Childtwo=e

我收到此错误:
AttributeError:'NoneType'对象没有属性'text'
答案 0 :(得分:1)
您可以遍历csv并仅处理具有匹配Parent
元素的Childone
元素(使用XPath predicate)。
此外,您已经知道Childone
元素的值,因此您只需要Childtwo
的值...
XML输入(test.xml)
<doc>
<Parent>
<Childone>1</Childone>
<ParentTwo>
<Childtwo>a</Childtwo>
</ParentTwo>
<ParentTwo>
<Childtwo>b</Childtwo>
</ParentTwo>
</Parent>
<Parent>
<Childone>2</Childone>
<ParentTwo>
<Childtwo>c</Childtwo>
</ParentTwo>
<ParentTwo>
<Childtwo>d</Childtwo>
</ParentTwo>
</Parent>
<Parent>
<Childone>3</Childone>
<ParentTwo>
<Childtwo>c</Childtwo>
</ParentTwo>
<ParentTwo>
<Childtwo>e</Childtwo>
</ParentTwo>
</Parent>
</doc>
CSV (test.csv)

Python
import xml.etree.ElementTree as ET
import csv
tree = ET.parse("test.xml")
with open('test.csv', 'rb') as f:
reader = csv.reader(f)
for i, row in enumerate(reader):
if i:
print ""
for childtwo in tree.findall(".//Parent[Childone='{}']/ParentTwo/Childtwo".format(row[0])):
print "ChildOne={childone} ChildTwo={childtwo}".format(childone=row[0], childtwo=childtwo.text)
输出
ChildOne=2 ChildTwo=c
ChildOne=2 ChildTwo=d
ChildOne=3 ChildTwo=c
ChildOne=3 ChildTwo=e
