【问题描述】：

您好，我之前尝试过问这些问题，但我无法正确解释。 我从应用程序获取 html 格式的报告，该文件正在保存在我的本地目录中，并且该 html 文件包含许多表，但我想从文件中提取特定表，因为我发布的 html 文件很大小部分在sn-p中方便理解。

现在，如果您运行 sn-p，您可以看到四个表，因为实际上 html 文件由多个表组成，现在有一件事很常见，例如有多个表带有标题 - 名称、开始时间、结束时间、状态，所以我正在尝试提取 html 文件中带有标题名称、开始时间、结束时间、状态的所有表并导出到 csv，因为在运行 sn-p 时，html 文件中有多个带有这些标题的表，你会明白的，我已经写了脚本这给了我在 excel 中格式不正确的所有内容。

import pandas as pd 
url = "table1.html"
goal = pd.read_html(url)[0]

goal.to_csv("data.csv")

但无法获取数据，我已经尝试使用带有类的“find_all”属性的“bs4”，但正如您看到的 html 代码有点复杂，所以任何想法都会受到赞赏。

PS : 作为编程和这些平台的新手。 感谢您的帮助！

    编辑： 'Dedupe' 和 'Compression' 在第 0 列内的字符串中，在前面的示例中，我使用 &lt;30 删除它们

    如果你想要这些参数，你需要采用不同的方式，从这些字符串中也可以获得其他数据。

    压缩示例：

    df_all=pd.DataFrame()
df=pd.read_html(url)
for df1 in df:
    df_all=df_all.append(df1)
df_all=df_all[
    df_all[0].str.len()>50
]

df_all['Compression']=df_all[0].str.extract(r'Compression (.*x)')[0]
print(df_all['Compression'].reset_index(drop=True))
#work with regex
0     1.0x
1     1.0x
2     1.0x
3     1.0x
4     1.0x
5     1.0x

    【讨论】：

    • 谢谢你！它起作用了，你是一个救世主，我在这些问题上挣扎了几个小时。只是好奇还有两个数据，例如“重复数据删除”和“压缩”，它们在另一个表中，但是有相同的工作报告，我可以用这些数据提取详细信息吗？
    • 感谢您的响应，但正如您建议的压缩和重复数据删除它只提供这两列数据我正在尝试获取这些数据以及以前的名称，状态加上这两个压缩的两列并在一张表中删除重复数据
    • @rohan 不，您也可以获取名称等，只需逐步打印 df 即可看到模式
