Editing Regex Code -

-

i hoping can me think regex problem.

i have program takes piece of html code , extracts phone numbers , separates them semi colons. change extracts between 2 specific text strings backslashes in between. example

stringone/******/stringtwo stringone/876876876876876/stringtwo stringone/abcdefghijklmnopqrstuvwxyz/stringtwo

before , after total string there may or may not spaces, letters, numbers or special characters.

i have tried regex can't figured out. assume (and instinct) line needs changing one:

    .pattern = "(\+([\d \(\)-]+){10,15})|((\d( |-))?\(?\d{2,4}\)?( |-)\d{3,4}( |-)\d{3,4})|(\d{3,4}( |-)\d{7})"

but entire code follows:

function main ( strtext )      dim strresult      strresult = extract_phone_numbers ( strtext )      main = strresult  end function  ' function extracts phone numbers specific string using pattern matching (a regular expression).  function extract_phone_numbers ( strtext )      dim strresult      set regularexpressionobject = new regexp      regularexpressionobject     .pattern = "(\+([\d \(\)-]+){10,15})|((\d( |-))?\(?\d{2,4}\)?( |-)\d{3,4}( |-)\d{3,4})|(\d{3,4}( |-)\d{7})"     .ignorecase = true     .global = true     end      set objmatches = regularexpressionobject.execute( strtext )      each objmatch in objmatches         if ( instr ( strresult, objmatch.value ) = 0  )              if ( len ( strresult ) > 0  )                  strresult = strresult + "; "             end if                   strresult = strresult + objmatch.value         end if           next      set regularexpressionobject = nothing      strresult = trim ( strresult )      extract_phone_numbers = strresult  end function

can me changed?

  1. in general, pattern matching pattern stringone/[^/]*/stringtwo, including slashes
  2. to match inside, not including slashes, there several ways. if flavor supports lookarounds, go this: (?<=stringone/)[^/]*(?=/stringtwo)
  3. vbs doesn't support lookbehind, need match whole string, capturing wanted part group 1: stringone/([^/]*)/stringtwo

on the demo, @ group 1 captures in right pane. note in regex tester slashes had escaped.

explanation

stringone/ matches literal stringone/, negated character class [^/] matches 1 character not /, , * quantifier repeats 0 or more times, match final /stringtwo.

php - Changing the visibility scope of parent methods in child classes -

-
i've got validator class , uservalidator class extends it. my validator has public method setrule(...) public visibility. when extend want change visibility of setrule(...) parent method private/protected within child it's visible child , no outsiders can call method from child. is possible? if so, how achieve it? from architectural point of view not recommended. stated in comments clean way set method protected children can access it. i cannot think of single use case put me in need call public method on parent class not allowed call on child class. that's against open/closed principle. classes should open extension, not modification. since not question i'll provide way how can achieved though. note: this method makes use of class responsible instantiation it's hack. solution not make use of php's native language features when throwing accessibility errors. first let's define classes had <?php class validator { ...
