python - 使用BeautifulSoup根据属性检索信息

Question

<resultsummary>
    <resultticker category="executed">
        <count>12</count>
        <percentage>1.0</percentage>
        <id xlink:href="...">id_num</id>
        <id xlink:href="...">id_num</id>
    </resultticker>
    <resultticker category="done">
        <count>16</count>
        <percentage>0.6</percentage>
        <id xlink:href="...">id_num</id>
        <id xlink:href="...">id_num</id>
    </resultticker>
</resultsummary>

我正在使用BeatifulSoup4我使用命令 soup.find("resultsummary") 得到上面的响应。我想做的是，我想检索 count那是在 resultticker标记并按 category 对其进行分类属性。

所以，我想得到，{ executed: 12, done: 16 } .

我尝试做soup.find("resultsummary").find('resultticker')['category']像这样的东西，但它只是给了我属性的名称 executed但不是标签内的信息。

有什么帮助吗？提前致谢。

用途:

from bs4 import BeautifulSoup

html = """<div>
    <resultsummary>
    <resultticker category="executed">
        <count>12</count>
        <percentage>1.0</percentage>
        <id xlink:href="...">id_num</id>
        <id xlink:href="...">id_num</id>
    </resultticker>
    <resultticker category="done">
        <count>16</count>
        <percentage>0.6</percentage>
        <id xlink:href="...">id_num</id>
        <id xlink:href="...">id_num</id>
    </resultticker>
</resultsummary>
</div>"""

result = {}
soup = BeautifulSoup(html, "html.parser")
for resultticker in soup.find("resultsummary").find_all('resultticker'):  #iterate each resultticker 
    result[resultticker['category']] = resultticker.count.text  #Key=category & Value=count
print(result)

输出:

{'executed': '12', 'done': '16'}
