从ElementTree获取属性名称和值

I have an XML <root> element with several attributes. I've been using the ElementTree package.

我有一个带有多个属性的XML 元素。我一直在使用ElementTree包。

After I've parsed a tree from an xml file, I'm getting the document root, but I want to get the requested attribute, or even the entire list of attributes.

在我从xml文件解析树之后，我得到了文档根目录，但我想获取所请求的属性，甚至是整个属性列表。

<root a="1" b="2" c="3">
    </blablabla>
</root>

How can I retrieve all attribute names and values for a <root> element with ElementTree?

如何使用ElementTree检索元素的所有属性名称和值？

3 个解决方案

#1

Each Element has an attribute .attrib that is a dictionary; simply use it's mapping methods to ask it for it's keys or values:

每个元素都有一个属性.attrib，它是一个字典;只需使用它的映射方法来询问它的键或值：

for name, value in root.attrib.items():
    print '{0}="{1}"'.format(name, value)

要么

for name in root.attrib:
    print '{0}="{1}"'.format(name, root.attrib[name])

or use .values() or any of the other methods available on a python dict.

或者使用.values（）或python dict上可用的任何其他方法。

To get an individual attribute, use the standard subscription syntax:

要获取单个属性，请使用标准订阅语法：

print root.attrib['a']

#2

The attrib attribute of an ElementTree element (like the root returned by getroot) is a dictionary. So you can do, for example:

ElementTree元素的attrib属性（如getroot返回的根）是一个字典。所以你可以做，例如：

from xml.etree import ElementTree
tree = ElementTree.parse('test.xml')
root = tree.getroot()
print root.attrib

which will output, for your example

对于你的例子，它将输出

{'a': '1', 'b': '2', 'c': '3'}

Some nice loop you can use it will get for each element of the xmlObject it's tag, text and attribute it will work for 2 levels XML, it's not the best way to iterate but it can be useful for simple things...

你可以使用它的一些好的循环将获得xmlObject的每个元素它的标签，文本和属性它将适用于2级XML，它不是迭代的最佳方式，但它对简单的事情有用...

for headTag in xmlObject.getchildren():
    print headTag.tag, headTag.text, headTag.attrib
    for bodyTag in headTag.getchildren():
        print "\t", bodyTag.tag, bodyTag.text, bodyTag.attrib
