The zero-or-more character (*) will match a string of any length. To specify how many characters we’d like to match after the character, we need to use a quantifier. The \s and \S are included in square brackets which say that we’d like to match any of them in any order: /a / Edit with Regexity It’s similar to the dot character (.) which matches everything except new-lines. So essentially, the \s\S combination matches everything. while non-whitespace characters include all letters, numbers, and punctuation. Whitespace characters include spaces, tabs, linebreaks, etc.
We start the expression by listing the character we want to extract after (in this case the letter a): /a / Edit with RegexityĪfter this character, we specify that we’d like to match all whitespace characters (\s) and all non-whitespace characters (\S). The following regular expression will return everything following the first occurrence of the character “a”. Method 1: Match everything after first occurence Some methods search for whitespace and non-whitespace characters following the character, while other methods make use of positive look-behinds. For instance, you’d like to extract the query string from a URL, which follows a question mark.Ī regular expression that matches everything after a specific character can be written in more than one way. Sometimes we’d like to extract everything from a body of text that follows a specific character.
