Extracts one string that matches the regular expression and extracts its subpatterns (Capturing groups). For example, if the regular expression (\\d{4})-(\\d{2})-(\\d{2})<\/code> is set, the first complete match in the text\u2014formatted as YYYY-MM-DD\u2014will be extracted, and then the individual values for YYYY, MM, and DD will also be captured. \"2025-05-19\"<\/code> \u2192 \"2025\"<\/code>, \"05\"<\/code>, \"19\"<\/code>.<\/p>\n\n\n\n
