I hope all of this helps.

The strategy you are using is a bad one.
1. You have to keep your data aligned.
    Let us assume the page looks like this.
    template =3D "<h1>%s</h1>Hello %s"
    Then you change it to this.
    template =3D "<h1>%s</h1><h2>%s</h2>Hello %s"
    You have to make sure to apply all the data in the right order.
2. Redundant use. You have to supply the same data repeatedly.
    Hello %s, It is nice know that your name is %s.
    %s, we were wondering if your name has always been %s.
3. The problem you mentioned.  % being in the actual page.
    Not really solvable.  Choose another character or combination
    of characters OR escape it like you are doing.

Now lets solve the rest of these.
1. Have a replace_all() function.

        -- http://eulogs.unkmar.com/logs/Eu.20020726.log.html#l60
        function replace_all(sequence string, sequence to_replace, sequence=

replace_with)
          integer m, lt
          sequence result
          lt =3D length(to_replace)
          result =3D ""
          m =3D match(to_replace, string)
          while m do
            result &=3D string[1..m-1] & replace_with
            string =3D string[m+lt..length(string)]
            m =3D match(to_replace, string)
          end while
          return result & string
        end function
        puts(1, replace_all("Lucius Lamar Hilley III", "L", "LL"))
2. Use named tokens.
    template =3D "<h1>~HEADER~</h1>Hello ~NAME~ Double tilde is actual ~~"
    template =3D replace_all(template, "~~", {1000})
    for A =3D 1 to length(form_names) do
      template =3D replace_all(template, form_names[A], form_values[A])
    end for
    template =3D replace_all(template, {1000}, "~")

Subject: DHTML and CGIs in Euphoria




Hi Euphorians;

I=B4m working with some CGIs in Euphoria for creating dinamic html pages,
based on data sent in by the client and retrived from an edb database.

For this purpose, I=B4m using the "%s" option inserted in some places of th=
e
html code:

For example:

text=3D{"Yellow","Banana"}
printf(1,<h1>%s</h1><h2>%s</h2>,text)


This works great, BUT, there is a big problem.
A lot of instructions in HTML use the % simbol. So, if I create a HTML page=

using tables for example, I have to take a lot of care with the command
width=3D"xx%" and change all of them to width=3D"xx%%".

My question is :  Is there any other way in euphoria for create dinamic
HTML pages ? Is the strategy I=B4m using for this a good one ? Any
suggestions about creating cgi scripts in euphoria are welcome !

Thanks

Rubens
