如何注释掉一个 XML 元素(使用 minidom DOM 实现)

问题描述

我想注释掉 xml 文件中的特定 XML 元素.我可以删除该元素，但我更愿意将其注释掉，以防以后需要.

I would like to comment out a specific XML element in an xml file. I could just remove the element, but I would prefer to leave it commented out, in case it's needed later.

我现在使用的删除元素的代码是这样的:

The code I use at the moment that removes the element looks like this:

from xml.dom import minidom

doc = minidom.parse(myXmlFile)
for element in doc.getElementsByTagName('MyElementName'):
if element.getAttribute('name') in ['AttribName1', 'AttribName2']:
    element.parentNode.removeChild(element)
f = open(myXmlFile, "w")
f.write(doc.toxml())
f.close()

我想修改它，以便将元素注释掉而不是删除它.

I would like to modify this so that it comments the element out rather then deleting it.

推荐答案

以下解决方案正是我想要的.

The following solution does exactly what I want.

from xml.dom import minidom

doc = minidom.parse(myXmlFile)
for element in doc.getElementsByTagName('MyElementName'):
    if element.getAttribute('name') in ['AttrName1', 'AttrName2']:
        parentNode = element.parentNode
        parentNode.insertBefore(doc.createComment(element.toxml()), element)
        parentNode.removeChild(element)
f = open(myXmlFile, "w")
f.write(doc.toxml())
f.close()
