Question

내 XML을 작동하지 않습니다.

doc = ET.parse("an.xml") 
root = doc.getroot() #Returns the root element for this tree. 
root_new = ET.Element("animals") 
for child in root: 
    name = child.attrib['name'] 
    fullname = child.attrib['fullname'] 

for g in root.findall("*/food"): 
    animal = ET.SubElement(root_new, "animal") 
    food  = ET.SubElement(animal, "food") 
    food.text = g.text 
    animal.set("name",name)    
    animal.set("fullname",fullname) 

tree = ET.ElementTree(root_new) 
tree.write(sys.stdout) 

그러나 단지 마지막 값

<animals> 
    <animal fullname="fullbla" name="blabla"><food>milk</food></animal> 
    <animal fullname="fullbla" name="blabla"><food>rice</food></animal> 
    <animal fullname="fullbla" name="blabla"><food>meat</food></animal> 
    <animal fullname="fullbla" name="blabla"><food>grass</food></animal> 
</animals> 

그리고 음식 노드도 잘못, 어떻게 내 입력 XML 똑같이 반복 할 수는 무엇입니까?

Answer 1

코드는 사용자가 객체의 자식 그룹 함께`food` 태그를해야이

doc = ET.parse("test.xml") 
root = doc.getroot() #Returns the root element for this tree. 
root_new = ET.Element("animals") 
for child in root: 
    name    = child.attrib['name'] 
    fullname   = child.attrib['fullname'] 
    animal = ET.SubElement(root_new, "animal") 
    animal.set("name",name)    
    animal.set("fullname",fullname) 

    for g in child.findall("food"): 
     food = ET.SubElement(animal, "food") 
     food.text = g.text 

tree = ET.ElementTree(root_new) 
tree.write(sys.stdout) 

Answer 2

두 가지 문제점이 있습니다. 첫 번째는 들여 쓰기입니다.이 루프는 중첩 된 루프로 간주됩니다. 두 번째 문제는 당신이 상관없이에있는 노드의 모든 food 항목을 받고 있음을 의미한다 root.findall을 사용하고 있다는 것입니다 대신을 시도해보십시오.

for child in root: 
    name    = child.attrib['name'] 
    fullname   = child.attrib['fullname'] 
    # create "animal" here 
    animal = ET.SubElement(root_new, "animal") 
    animal.set("name",name)    
    animal.set("fullname",fullname) 
    for g in child.findall("food"): 
     # create "food" here 
     food  = ET.SubElement(animal, "food") 
     food.text = g.text 

:

... 
for child in root: 
    name = child.attrib['name'] 
    fullname = child.attrib['fullname'] 
    animal = ET.SubElement(root_new, 'animal') 
    for g in child.findall("food"): 
     food = ET.SubElement(animal, "food") 
     food.text = g.text 
     animal.set('name', name)    
     animal.set('fullname', fullname) 

Answer 3

당신은 중첩 루프를 필요
