java - RegEx to extract text between a HTML tag

Question

I'm looking a regular expression which must extract text between HTML tag of different types.

For ex:

<span>Span 1</span> - O/p: Span 1

<div onclick="callMe()">Span 2</div> - O/p: Span 2

<a href="#">HyperText</a> - O/p: HyperText

I found this particular piece <([A-Z][A-Z0-9]*)[^>]*>(.*?)</1> from here But this one is not working.

Your comment shows that you have neglected to escape the backslashes in your regex string.

And if you want to match lowercase letters add a-z to the character classes or use Pattern.CASE_INSENSITIVE (or add (?i) to the beginning of the regex)

"<([A-Za-z][A-Za-z0-9]*)\b[^>]*>(.*?)</\1>"

If the tag contents may contain newlines, then use Pattern.DOTALL or add (?s) to the beginning of the regex to turn on dotall/singleline mode.
