This is not purely a prototype question so if anyone wants to point me to a different location (other than "Google this" cuz I already did :), feel free. I just got the new PragProg book on Prototype and coincidentally was writing a fair amount of JS. Ok, there''s a question in here somewhere: I have to parse: [q]hello[q]hello1[/q]out[/q]for good and treat the [q] blocks as quoting levels for email. That means, I''ll be substituting <div class=q1> for the first level, q2 for the second, etc. I''m hoping not to have to tokenize the whole thing. Is there a straightforward way to match and process the nestings using a function as a second argument to gsub?

Thanks for the pointer. It seems that wrap allows you to conditionally change existing functionality, allowing for fallback to original functionality in the default case. Good if you don''t want to edit nice, tested framework code. In my case, I want to replace tags from the outside in kind of iteratively. So, in pseudo-code: startString = ''[q]outside level[q]inner level[/q]back to outer[/q]completely outside quote block''; I''m guessing that iteration and greedy matching is the only way to do it. Am I missing something?

wouldn''t just replacing [q] with <div class=''padleft''> and [/q] with </div> give you that effect if the class gave some left padding? You''d end up with nested divs which each gave their own amount of padding... On Nov 9, 2007 10:43 AM, s.ross <cwdinfo-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> > > Thanks for the pointer.

Yeah, that''s what I wound up doing. I did (at one point) want to count and style differently based on level of nesting, but prob''ly not worth the extra work. thx Gareth Evans-6 wrote:> > wouldn''t just replacing [q] with <div class=''padleft''> and [/q] with > </div> > give you that effect if the class gave some left padding? > You''d end up with nested divs which each gave their own amount of > padding... > > > On Nov 9, 2007 10:43 AM, s.ross <cwdinfo-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > >> >> >> Thanks for the pointer.

You can still do that.
If you, say used ''quote'' as your class and replaced [q] with
<div
class=''quote''> and [/q] with </div> then in your css
you could use
div.quote
{
padding-left:10px;
}
div.quote div.quote /* 2nd level */
{
padding-left:20px; /* yeilds a total of 30px padding */
}
div.quote div.quote div.quote /* third level */
{
padding-left:30px; /* total of 60px padding */
color:#999999;
}
etc.
You''d still need to define a fixed number of quote styles but once you
get
beyond, say, 4, i''d just leave them all the same.

Steve,
I think this is all you need:
var i = 0,
reStart = /\[q\]/g,
reEnd = /\[\/q\]/g,
content = ''[q]hello[q]hello1[/q]out[/q]'';
content.replace(reStart, ''<div class="q'' + (i++) +
''">'').replace(reEnd, ''</div>'')
keep it simple ; )
best,
kangax

Hey kangax, isn''t using the same class name and chaining them in the css even simpler?
