How to Extract Multiline Text Between Tags in JavaScript with Regex?

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 ([sS]), you can ensure that your regex pattern successfully matches multiline text between the specified HTML tags, even when there are newlines within that text.
