Getting number from the string using regexp

Use HTML::TableExtract.

In javascript you can do this:

var num = parseInt(someString.replace( /\D/g , ''));

I think you have a slightly peculiar regex implementation. What's the environment?

   s/^[^\d]*\(\d+\)<[^\d]**$/\1/

Has to be worth a go, though. Check whether the set pattern needs [ or [ and if it allows character classes (\d) first. If no character classes 0-9 should do it.

regex (?:<(?:[^>])+>)(\d+)(?:(?:<\/[^>]+)+>) capture only the numbers from your text that are betwen html tags

Although you don't explain what language you're using, the answer is simple.

When you have captured expressions (parenthesis), there are multiple results.

The first one, #0, is always the whole match. Since you have .* before and after the digits, the extra HTML is included in the result.

However, in the second match, #1, you should have only the number. The way to retrieve this result varies depending on the language, but if you update your question, we may be able to help you in that regard.

Edit:

public static String extractNumber(String input) {
    Pattern p = Pattern.compile("s/(\\d+)/");

    Matcher m = p.matcher(input);

    if(m.find()) {
        String num = m.group(1);
        return Integer.parseInt(num);
    }

    return null;
}

This will extract the first number it finds in the input text. And, it demonstrates how to use groups as well.

I haven't tested it since I don't have a proper java environment set up at the moment, but it looks okay. Let me know if you have any problems.
