python - 如何检索使用 minidom 创建的 xml？

Question

 from xml.dom.minidom import Document

 def generateXML():

    # Create the minidom document
    doc = Document()

    # Create the <discover> base element
    discover = doc.createElement("discover")
    doc.appendChild(discover)


    # Create the main <host> element
    host = doc.createElement("host")
    host.appendChild(discover)

    # Create the main <ip> element
    ip = doc.createElement("ip")
    ip.appendChild(host)

    # Assign <ip> element with IP address
    ipaddrr = doc.createTextNode('10.193.184.72')
    ip.appendChild(ipaddrr)

    # Create the main <hostname> element
    hostname = doc.createElement("hostname")
    hostname.appendChild(host)

    # Assign <hostname> element with hostname
    hostname_value = doc.createTextNode('darknight')
    hostname.appendChild(hostname_value)

    # Create the main <ostype> element
    ostype = doc.createElement("ostype")
    ostype.appendChild(host)

    # Assign <ostype> element with ostype
    ostype_value = doc.createTextNode('mac')
    ostype.appendChild(ostype_value)

    return doc.toprettyxml()

 print generateXML()

现在当我打印它时 -- 它只是返回 <?xml version="1.0" ?> ，我实际上想要我创建的整个 xml。请帮忙

您附加元素的方式错误。它是 parentnode.appendChild(childnode)，您已将其编写为 childnode.appendChild(parentnode)
