删除 XML 文档中每个节点的所有属性

Question

I have a Node(element) object of an XML Document. I need to remove all the attributes of it's and it's Sub Nodes. How do i do this in python? i'm using xml.dom.minidom

Answer 1

Something along the lines of:

dom = xml.dom.minidom.parseString(document)

for node in dom.childNodes:
    if node.attributes:
        for key in node.attributes.keys():
            node.removeAttribute(key)

Answer 2

Rob's answer won't work nowadays, it will cause a RunTimeError when you try to remove a key from a dict you are using as an Iterator

So, before trying to remove you should clone the keys first, something like this would work

keys = list(xml_node.attributes.keys()) if xml_node.attributes else []
for attribute in keys:
    xml_node.removeAttribute(attribute)

这很容易使用PyQuery ，它有一个删除属性方法： http : //packages.python.org/pyquery/api.html#pyquery.pyquery.PyQuery.removeAttr
