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

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
