Python XML 到字典以迭代项目

Question

我有以下 XML 示例

<?xml version="1.0"?>
<test>
    <items>
        <item>item 1</item>
        <item>item 2</item>
    </items>
</test>

我需要在 python 中的 for 循环中遍历每个标记。如果尝试了很多东西，但我就是做不到......

感谢帮助

我个人使用xml.etree.cElementTree ，因为我发现它工作得很好，速度很快，easy to use , 和 works well with big (>2GB) files .

import xml.etree.cElementTree as etree

with open(xml_file_path) as xml_file:
    tree = etree.iterparse(xml_file)
    for items in tree:
        for item in items:
            print item.text

在交互式控制台中

>>> x="""<?xml version="1.0"?>
<test>
    <items>
        <item>item 1</item>
        <item>item 2</item>
    </items>
</test>"""
>>> x
'<?xml version="1.0"?>\n<test>\n    <items>\n        <item>item 1</item>\n        <item>item 2</item>\n    </items>\n</test>'
>>> import xml.etree.cElementTree as etree
>>> tree = etree.fromstring(x)
>>> tree
<Element 'test' at 0xb63ad248>
>>> for i in tree:
        for j in i:
            print j


<Element 'item' at 0xb63ad2f0>
<Element 'item' at 0xb63ad338>
>>> for i in tree:
        for j in i:
            j.text

'item 1'
'item 2'
>>>
