\nIf you have something like “hello|world|!” and you want to get only the first part before the first Delimiter (which obviously is “|”) your first try could look like:
\n(.*)\\|<\/code>
\nThat one would match “hello|world” since by default Regex is Greedy (aka. “take as much as possible”).<\/p>\n
\n([^\\|]+)<\/code>
\nThis one does match unless the “|” Sign is found.<\/p>\n
\n(.*?)\\|<\/code>
\nThe added “?” makes it Non-Greedy (aka. “take as less as possible)<\/p>\n
\nSometimes you want to create a Group which is not captured. Just begin those Groups with an “?:” and it will not get captured.
\nExample:
\n(?:abc)<\/code><\/p>\n","protected":false},"excerpt":{"rendered":"
