Regex for Extracting Multiline Text between Two Tags in JavaScript

You're facing challenges in extracting text from an HTML string using a regex pattern. Specifically, the multiline flag (/m) doesn't seem to be working when there are newlines in the HTML.

To address this issue, you need to utilize the "/.../s" modifier, commonly referred to as the "dotall" modifier. However, it's important to note that this modifier does not exist in vanilla JavaScript.

Workarounds without Dotall Modifier:

If you can't use the /s flag in your current JavaScript environment, consider a workaround using a character class that includes both whitespace and non-whitespace characters:

[\s\S]

In your case, the regex would look like this:

/<div>

Modern JavaScript: Dotall Modifier Support

In modern JavaScript environments that support ES2018, you can directly use the "/s" (dotAll) flag. This flag makes the dot (.) character in the regex match newline characters as well.

Therefore, your original regex could be rewritten using the /s flag:

/<div>

By using the dotall modifier (/s) or its workaround ([\s\S]), you can ensure that your regex pattern successfully matches multiline text between the specified HTML tags, even when there are newlines within that text.
