In PHP =you have to (get to) specify just when/where you start and stop output.. =but with webdna everything but the tags themselves is output - as it =appears in your source doc. =20As a result of this situation, old-school webdna code used a ton of =comments to trim whitespace,=20...like [!]=20[/!] so.You can also use [function]s which only [return] what you say to =return...You can also do your manipulation/processing as always, but store any =developing output into concatenating [text] vars.. and then finally when =you are ready to actually output, then just drop in the [text] var. =This method allows to you do [grep], etc. to strip out unwanted chars, =or even add in wanted chars. Like you can replace all actual carriage =return/line feed chars with
