Found the handler:  this will strip tags and parse things like "'"
Caution: It has been modified to work with a particular app I wrote, so step
through it and adjust to your recipe.

function StripTags pHtml
  local tRegex,tPrevText
  get  ("é,à,ç")
  get  it & (",>,<,ê")
  get  it & (",è,©,•")
  get  it & (",',·,&")
  -- add more chars if you wish, then...
  constant kHtml = it
  constant kConvertedHtml = "é,à,ç,>,<,ê,è,©"
  --using contants means you cannot accidentally
  --    modify these vars and damage the results
  -----  
  replace numtochar(13) with empty in pHtml

  put replacetext(pHtml,tRegex,"") into pHtml

  ----- repeat replacements until there are no changes
  repeat until tPrevText is pHtml
    put pHtml into tPrevText
    put replacetext(pHtml," +",space) into pHtml

  filter pHtml without empty
  replace numtochar(160) with empty in pHtml
  -----
  replace """ with quote in pHtml
  repeat with i = 1 to the number of items of kHtml
    replace item i of kHtml with item i of kConvertedHtml in pHtml
  end repeat
  -----
  --put pHtml into msg  --let's you see the result in the msg box
  return pHtml
end StripTags
