问题 I have an XML file with nodes that looks like this: <trkpt lat="-37.7944415" lon="144.9616159"> <ele>41.3681107</ele> <time>2015-04-11T03:52:33.000Z</time> <speed>3.9598</speed> </trkpt> I am using lxml.etree.iterparse() to iteratively parse the tree. I loop over each trkpt element's children and want to print the text value of the children nodes. E.g. for event, element in etree.iterparse(infile, events=("start", "end")): if element.tag == NAMESPACE + 'trkpt': for child in list(element):

问题 <grandParent> <parent> <child>Sam/Astronaut</child> </parent> </grandParent> I want to modify the above XML by adding another child tag inside parent tag. I'm doing something like this.. tree = ET.parse("test.xml") a=ET.Element('parent') b=ET.SubElement(a,"child") b.text="Jay/Doctor" tree.write("test.xml") Is this the correct way of modifying the xml file? Any better way? or what else should I be taking care of in the above code? 回答1: Your code creates a whole new tree and adds Jay to it. You

问题 When parsing an xml file into a Python ElementTree the attributes' order is mixed up because Python stores the attributes in a dictionary. How can I change the order of the attributes in the dictionary? 回答1: Your self-answer is as you said long and cumbersome. It doesn't need to be. Also it will fail if (1) there are more than 10 keys (2) a dict has fewer keys than than expected. Try this; it's much simpler: >>> ordered_keys = ('z', 'y', 'e', 'x', 'w') # possible keys, in desired order Note:

问题 I'm using Python 3.2's xml.etree.ElementTree , and am attempting to generate XML like this: <XnaContent xmlns:data="Model.Data"> <Asset Type="data:MyData"> ... The format is out of my control (it's XNA). Notice that the data XML namespace is never actually used to qualify elements or attributes, but rather to qualify attribute values to XNA. My code looks like this: root = Element('XnaContent') ET.register_namespace('data', 'Model.Data') asset = SubElement(root, 'Asset', {"Type": "data:MyData
