Your old HTML code should be modernized to current HTML5 & CSS web standards.

To find numeric values not enclosed in double quotes, you can use a negative lookbehind and lookahead assertion in your regex pattern. Here's an example:

(?<!")\b\d+\b(?!")

Explanation:

(?<!") is a negative lookbehind assertion that ensures the numeric value is not preceded by a double quote.
\b\d+\b matches a numeric value. \b is a word boundary to ensure it's a standalone number, and \d+ matches one or more digits.
(?!") is a negative lookahead assertion that ensures the numeric value is not followed by a double quote.
