使用Python向XML添加容器元素

Question

这是我的密码：

from xml.dom import minidom
from xml.dom.minidom import parse
import xml.etree.ElementTree as ET 

xml_file = "dummy.xml"
xmlFile = ET.parse(xml_file)

root = xmlFile.getroot() 
root.keys()

newroot = ET.Element("languages")

for child in root:
    if child.tag == "language":
        newroot.insert(1, newroot)
        xmlFile.write("fileName")
    else:
        print "no"

这是原始XML文件(虚拟.xml)地址：

<book>
    <title> Everyday Italian </title>
    <author> Giada DeLaurentiis </author>
    <language> English </language>
    <section> Cooking </section>
</book>

以下是我希望新XML（文件名）的外观：

<book>
    <title> Everyday Italian </title>
    <author> Giada DeLaurentiis </author>
    <languages>
    <language> English </language>
    </languages>
    <section> Cooking </section>
</book>

请帮忙。我似乎无法将容器元素“languages”正确地添加到新的XML文件中。你知道吗

谢谢

from xml.dom import minidom
from xml.dom.minidom import parse
import xml.etree.ElementTree as ET 

xml_file = "dummy.xml"
xmlFile = ET.parse(xml_file)

root = xmlFile.getroot() 
root.keys()

newroot = ET.Element("languages")

for child in root:
    if child.tag == "language":
        newroot.insert(1, child)
        root.remove(child)
        root.insert(1, newroot)
        xmlFile.write("newdummy.xml")
    else:
        print "no"

您需要先将子级插入到newroot，然后将newroot插入到根。你知道吗
