Test, validate and match regular expressions
This regex matches a specific JavaScript code pattern for handling audio playback on a button with the class 'buttonaudio'. It captures two statements: one that sets the 'src' attribute of a sound object to the value of the clicked button's 'data-audiosrc' attribute, and another that calls the 'play()' method on that sound object. The sound object reference is loosely matched using wildcards to accommodate varying variable names. This is useful for searching, analyzing, or refactoring audio-related event handler code in frontend projects.
