Question

 import xml.etree.ElementTree as ET

 var3 = raw_input("Enter the root Element: \n")
 root = ET.Element(var3) 
 var4 = raw_input("Enter the sub root Element: \n")
 doc = ET.SubElement(root, var4)   

 no_of_rows=input("Enter the number of Element for XML files: -    \n")

 def printme():

    var = raw_input("Enter Element: - \n")
    var1 = raw_input("Enter Data: - \n")

    ET.SubElement(doc, var).text =var1

    return;

    for num in range(0, no_of_rows):
        printme()

    tree = ET.ElementTree(root)
    file = raw_input("Enter File Name: - \n")
    tree.write(file)

    ET.ElementTree(root).write(file, encoding="utf-8", xml_declaration=True)         
    print "Xml file Created..!!"

我想使用python动态创建xml。

如何创建多个子根？

我从控制台给出文件名，以便在xml中存储书面元素。它给出了这个错误：

TypeError: descriptor 'write' requires a 'file' object but received a 'str'

我该怎么办？

Answer 1

你没有。来自用户的元素，但您没有使用它。使用循环并从循环中获取用户的元素详细信息，如下所示：

import xml.etree.ElementTree as ET
try:
    no_of_rows=int(input("Enter the number of Element for XML files: -    \n"))
    root = input("Enter the root Element: \n")
    root_element = ET.Element(root)
    for _ in range(1, no_of_rows):
        tag = input("Enter Element: - \n")
        value = input("Enter Data: - \n")    
        ET.SubElement(root_element, tag).text = value

    tree = ET.ElementTree(root_element)
    tree.write("filename.xml")

    print("Xml file Created..!!")
except ValueError:
    print("Value Error")
except:
    print("Exception Occuured")
    enter code here

我希望这是你想要实现的目标。

如果你想创建xml，你可以这样做：

from lxml import etree
try:
   root_text = raw_input("Enter the root Element: \n")
   root = etree.Element(root_text)
   child_tag = raw_input("Enter the child tag Element: \n")
   child_text = raw_input("Enter the child text Element: \n")
   child = etree.Element(child_text )
   child.text =child_text 
   root.append(child)
   with open('file.xml', 'w') as f:
      f.write(etree.tostring(root))
      f.close()
except ValueError:
    print("Occured Error")

或者，如果你想要动态长度，你只需使用for循环。
