python-3.x - 使用python从html文件中的多个表中获取特定表
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 文件很大一小部分在片段中以供理解。

import pandas as pd
url = "table1.html"
goal = pd.read_html(url)[0]
goal.to_csv("data.csv")
但无法获得数据，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。谢谢您的帮助！

编辑：“Dedupe”和“Compression”位于第 0 列内的字符串中，在前面的示例中，我使用删除它们<30
如果您想要这些参数，则需要采用不同的方式，并且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
