java - Find between custom tag if between tag has text or not -
in below code can find text between <p|a|s>hello there</> such p|a|s , hello there without problem
pattern mfta_regex = pattern.compile("<(.+?)>(.+?)</>"); matcher matcher = mfta_regex.matcher("<p|a|s>hello there</>"); if (matcher.find()) { log.e("tag ",matcher.group(1)); log.e("text ",matcher.group(2)); } now when don't have p|a|s <>hello there</> matcher couldn't find. in string p|a|s optional, how can change pattern.compile("<(.+?)>(.+?)</>"); resolve problem?
optional ? on group should outside group, i.e. after ):
<(.+)?> or if want match empty string, then:
<(.*)> see working example on regex101.com
