一行有效，但两行不适用于正则表达式，为什么？

Question

I'm using the RegEx practice tool to work on some web scraping.

https://extendsclass.com/regex-tester.html

(Laboratory Confirmed Cases )([clastexwid\\-.\\"= h<>\\/]+)([0-9]+)/s This is what I'm searching for.

These are what I'm searching.

<td class="text-white">Laboratory Confirmed Cases </td>

<td class="text-white">1264450</td>

If I put the text to be searched on the same line, there is a match. If not then there is no match.

Help?

I'm using Google Apps Script/Javascript.

Answer 1

You need to use \\n? which indicates that there might be a new line.

Something like this could work -

Laboratory Confirmed Cases <\\/td>\\n?<td class="text-white">(\\d+)<\\/td>

as seen here -

this will return the confirmed case numbers.

or depending on if the text is trimmed() or stripped() you might need two (\\n?\\n?) of them.
