python - 难以从 smarkets 解析 .xml 文件

Question

我有一个(巨大的).xml 文件，它或多或少是我设法用 Vim 加载的以下代码片段的变体。我一直在尝试做的是找到子标签 market 的 slug 名称为“正确分数”，然后我需要列出下面合约中的所有信息，或者迭代的方法以下契约(Contract)。

有人可以帮我吗？我已经完成了所有基本示例，但我的文件与在线示例不同，而且现在是凌晨 2 点...

import xml.etree.ElementTree as ET

#__________________________________
tree = ET.parse('get_this.xml')
root = tree.getroot()

for child in root:
    print "Match Names", child.attrib['name']
print


rows = root.findall('.//market')

for child in rows:
    if child.attrib['slug'] == 'correct-score':
        print child.attrib
        print child.attrib['id']

        #when I have found the id and correct score market, how do I work with the data below it?

文件片段。

Answer 1

如果您想要市场标签下的完整信息，并以 slug 名称作为正确的分数，请尝试使用以下代码。

import xml.etree.ElementTree as ET
tree = ET.parse('./sample.xml')
root = tree.getroot()
for child in root.findall('.//market'):
    if child.attrib['slug'] == 'correct-score':
        for ele in child.iter():
            print(ele.tag,ele.attrib) 

我把你的xml文件放在sample.xml中，希望对你有帮助
