Regular Expressions match line breaks, regular expressions match line breaks

At the beginning, we did not find many \ n html documents, and the results were in the format.

<Table [^>]>. * </table>

The data between tables is incorrect. According to Baidu encyclopedia, the solution is as follows:

\ S	Matches any blank characters, including spaces, tabs, and page breaks. It is equivalent to [\ f \ n \ r \ t \ v].
\ S	Match any non-blank characters. It is equivalent to [^ \ f \ n \ r \ t \ v].

Therefore, modify the mode:

<Table [^>] +> [\ s \ S] *? </Table>

? In non-Greedy mode, the system prompts that the regular expression matches to the first </table> and stops.
