HTML Tags removed from ASP/Javascript

[LuisRivera]

I was wondering if there was any built in function for ASP/Javascript that filtered out HTML Tags from any info entered by user (ie input text boxes etc)
Or do i have to create my own.

You can do it with ASP

'[ClearHTMLTags]

'  Purpose: This function clears all HTML tags from a
'           string using Regular Expressions.
'   Inputs: strHTML;
'            A string to be cleared of HTML TAGS
'	intWorkFlow;
'            An integer that if equals to 0 runs only the RegExp filter
'              .. 1 runs only the HTML source render filter
'              .. 2 runs both the RegExp and the HTML source render
'              .. >2 defaults to 0
'  Returns: A string that has been filtered by the function
	
function ClearHTMLTags(strHTML, intWorkFlow)
  'Variables used in the function
		
  dim regEx, strTagLess
		
  '---------------------------------------
  strTagless = strHTML
  'Move the string into a private variable
  'within the function
  '---------------------------------------

  'regEx initialization
  '---------------------------------------
  set regEx = New RegExp 
  'Creates a regexp object		
  regEx.IgnoreCase = True
  'Don't give frat about case sensitivity
  regEx.Global = True
  'Global applicability
  '---------------------------------------

  'Phase I
  '	"bye bye html tags"
  if intWorkFlow <> 1 then
    '---------------------------------------
    regEx.Pattern = "<[^>]*>"
    'this pattern mathces any html tag
    strTagLess = regEx.Replace(strTagLess, "")
    'all html tags are stripped
    '---------------------------------------
  end if
		
  'Phase II
  '	"bye bye rouge leftovers"
  '	"or, I want to render the source"
  '	"as html."

  '---------------------------------------
  'We *might* still have rouge < and > 
  'let's be positive that those that remain
  'are changed into html characters
  '---------------------------------------	

  if intWorkFlow > 0 and intWorkFlow < 3 then
    regEx.Pattern = "[<]"
    'matches a single <
    strTagLess = regEx.Replace(strTagLess, "<")

    regEx.Pattern = "[>]"
    'matches a single >
    strTagLess = regEx.Replace(strTagLess, ">")
    '---------------------------------------
  end if
		
  'Clean up
  '---------------------------------------
  set regEx = nothing
  'Destroys the regExp object
  '---------------------------------------	
		
  '---------------------------------------
  ClearHTMLTags = strTagLess
  'The results are passed back
  '---------------------------------------
end function
