Code - replace html entities with symbols

Submitted by Steve on Wed, 25 Jun, 2008 - 16:04

As a result of an enquiry from this forum post I followed up with a very quick "pseudo code" version of how to strip HTML entities from code and replace them with their corresponding symbols.

The Drupal Aggregator module also suffers from the fact that post titles are not HTML rendered. Even though the following code is not PHP but rather Realbasic I'm sure any skilled PHP developer should be able to convert/translate to PHP.

Without further ado, here's the code.

Function Convert_Html_Code_To_Symbol(pStr as string) As string
  // Version 1.04 - 2 Jun 2008.
  // Converts raw text, containing html symbol codes such as (" &) to their numerical equivalents (" &)
  // The numerical codes are retrieved from 'charactercodes.txt' text file in same directory as this program.
  // After codes changed to numerical codes then the string can be run through the RegEx converter, changing to symbols.
 
  Dim intPos as Integer
  Dim intAmp as integer
  Dim intSemiColon as integer
  Dim intLen as Integer
  Dim strKey as string
  Dim strReplace as string
  Dim strDone as string
 
  Dim x as Integer

  intLen = len(pStr)
  intAmp = instr(pStr, ";")
 
  While len(pStr) > 0
   
    intPos = instr(pStr, "&")

    if intPos = 0 then
      strDone = strDone + pStr
      pStr = ""
      exit while
    else
      if intPos > 1 then
        strDone = strDone + left(pStr,intPos - 1)
        pStr = right(pStr,len(pStr) - intPos +1)
      end if
