HTML Tables

[Jim Ault]

Here is one that used some RegEx that I sent to Eric Chatonet and he ramped
up to a real code function for removing tags.  Note that a couple steps are
commented out since the exact page you are trying to parse may or may not
need different treatment for spaces and returns.

Try this way, then tweak the "--replace" lines to see if that gives a better
result.
-------------------- start copy here
function StripTags pHtml
  local tRegex,tPrevText
  constant kHtml = 
"é,à,ç,>,<,ecirc;,è,©,•,',&m
iddot;,&"
  constant kConvertedHtml = "é,à,ç,>,<,ê,è,©"
  put kConvertedHtml into tempp
  put "," & numtochar(165) & "," & numtochar(39) & "," & numtochar(225) &
"," & numtochar(38) after tempp
  -----
  --replace return with space in pHtml
  --replace return with "MMMM" in pHtml
  
  replace numtochar(13) with empty in pHtml
  replace tab with empty in pHtml
  -----
  put replacetext(pHtml,"(?Usi)<SCRIPT.*</SCRIPT>","") into pHtml
  put replacetext(pHtml,"(?Usi)<STYLE>.*</STYLE>","") into pHtml
  put replacetext(pHtml,"(?Usi)<\?.*\?>","") into pHtml
  -----
  replace " " with space in pHtml
  replace "<BR>" with return in pHtml
  replace "<p>" with return in pHtml
  -----
  put  "<[^><]*>" into tRegex
  put replacetext(pHtml,tRegex,"") into pHtml
  put replacetext(pHtml,tRegex,"") into pHtml
  -----
  repeat until tPrevText is pHtml
    if keepRunning is "false" then exit StripTags
    put pHtml into tPrevText
    put replacetext(pHtml," +",space) into pHtml
    put replacetext(pHtml,"^ ","") into pHtml
  end repeat
  -----
  replace (space & return) with return in pHtml
  replace (return & space) with return in pHtml
  filter pHtml without empty
  -----
  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
  -----
  return pHtml
end StripTags
----------------------- end copy
