Regex - Get x number of characters from a string but html tags does not count towards the count












2














As the title suggests I need to get X amount of characters from a string but HTML is not including in the count.



Example string



Some <i>t</i>est <b>string</b> test


9 characters would output



Some <i>t</i>est


13 characters would output



Some <i>t</i>est <b>str


19 characters would output



Some <i>t</i>est <b>string</b> te


I'm not too sure where to go from the basic



(.*?){0,10}


Also, is there a way to make HTML encoded characters e.g. &lt; count as one character?

  • Very close I've changed it a little to ^(?:(?:<[^<>]*>)|(?:&[^s+]*;)*.){21} but I want the &.*; to count as one letter. any ideas?

To match a certain amount of chars from the string start excluding substrings like <...> from the count and counting &XX*; entities as one unit, you may use



^(?:&[^s;]*;|(?:<[^<>]*>)*.){20}


See the regex demo.



Details





  • ^ - start of string


  • (?: - start of a non-capturing group that will serve as a containter for the alternatives below:



    • &[^s;]*; - a &, 0 or more chars other than whitespace and ; and then ;


    • | - or


    • (?:<[^<>]*>)*. - 0 or more repetitions of <, 0+ chars other than < and > and then >, and then any char other than a line break char (use DOTALL modifier to match any char with .)




  • ){20} - end of the container group and the limiting quantifier tells the engine to match 20 consecutive occurrences of its pattern.

    To match a certain amount of chars from the string start excluding substrings like <...> from the count and counting &XX*; entities as one unit, you may use



    ^(?:&[^s;]*;|(?:<[^<>]*>)*.){20}


    See the regex demo.



    Details





    • ^ - start of string


    • (?: - start of a non-capturing group that will serve as a containter for the alternatives below:



      • &[^s;]*; - a &, 0 or more chars other than whitespace and ; and then ;


      • | - or


      • (?:<[^<>]*>)*. - 0 or more repetitions of <, 0+ chars other than < and > and then >, and then any char other than a line break char (use DOTALL modifier to match any char with .)




    • ){20} - end of the container group and the limiting quantifier tells the engine to match 20 consecutive occurrences of its pattern.
