这是我要转换为 csv 的 xml 文件，有人可以帮我在 python 中如何做吗？ 下面是我尝试使用的代码，但我还没有真正理解如何去做，看到了一些例子，但不是很清楚

from xml.etree import ElementTree

tree = ElementTree.parse('Store.xml')
root = tree.getroot()

for att in root:
    first = att.find('shops').text
    print('{}'.format(first))

但我这里没有。

Answer 1

Shops 没有文本，因此它不会打印任何内容。你需要达到你想要的水平

for att in root.findall('./data/shops/shop’):
    first = att.find('name')
    print('{}'.format(first.text))

给予

Bannockburn
Plainfield - North Plainfield

这里有一个很好的 ElementTree 资源：https://docs.python.org/3/library/xml.etree.elementtree.html

Answer 2

不是一个完整的解决方案，但要回答您为什么获得None，这是因为您的商店实际上更深一层，在data 标签下。

这段代码可能会让您了解如何访问底层属性，您可以将其收集到列表或其他容器中以构建您的 CSV。

from xml.etree import ElementTree

tree = ElementTree.parse('Store.xml')
root = tree.getroot()
data = root.find('data')

for shops in data:
    for shop in shops:
        name = shop.find('name').text
        sid = shop.attrib
        status = shop.find('status').text
        attrs = shop.find('shopAttributes')
        open_date = attrs.find(".//shopAttribute/[@attrName='shop_OPEN_DATE']").text
        print(f"Name: {name}, ID: {sid}, Status: {status}, open: {open_date}")

open_date 是如何使用XPath 访问属性的示例。代码返回：

Name: Bannockburn, ID: {'id': '204019'}, Status: Open, open: 2008-07-16
Name: Plainfield - North Plainfield, ID: {'id': '204020'}, Status: Open, open: 2007-05-18
