Hi Aaron,=20 I think Ken is right. I mean - I have done lots of webdna over the = years, and some coding with webdna and javascript talking to each = other.. not alot.. but just enough to comment..=20 ..and anyway i am guessing that what you will have to focus on is to = take total control of every character you output with webdna. 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. =20 As 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
, and replace all instances of = "someCRLFflag" with a real CR/LF char, when/where needed, for one = example. Play with it. Examine the evolving string of characters at various = steps to see what you are actually doing to the output as you generate = it.. step by step. - Govinda -------------- Old WebDNA talklist archives: http://dev.webdna.us/TalkListArchive/index.tpl?db=3Dwebdna-talk
