Regex to extract numbers/alphabets only

[hua]

Just wanna share my code that extracts only numbers, alphabets from a string using regex. Irrelevant character will be ignored.
Maybe there is a neater code

Code: Select all | Expand

function cExtractAlphabets(cStr)
  local a_  := hb_regexAll("[A-Za-z ]", cStr), cRet := "", aChar

  if a_ != nil
     for each aChar in a_
         cRet += aChar[1]
     next
  endif
return cRet // returns alphabet and space only
 

Code: Select all | Expand

function cExtractNum(cStr)
  local a_  := hb_regexAll("\d{1,}", cStr), cNum := "", aDigit

  if a_ != nil
     for each aDigit in a_
         cNum += aDigit[1]
     next
  endif
return cNum
