Question

I recursively pass through all the nodes in an XML:

def verify_elements_children(root):
    if root.childNodes:
        for node in root.childNodes:
            if node.nodeType == node.ELEMENT_NODE:
               if node.tagName in config_elements_children[node.parentNode.tagName]:
#                  print node.toxml()
                   verify_elements_children(node)

But I don’t know how to get all the attributes names of the selected the selected node?

You can simply access the attributes property, which is a NamedNodeMap, on which you can call items to get the string keys and values:

import xml.dom.minidom
n = xml.dom.minidom.parseString('<n a="1" b="2" />').documentElement
attrs = dict(n.attributes.items())
assert attrs == {'a': '1', 'b': '2'}
