Re: How do I use substrings in regular expressions?
Hi Michael, I agree with Richard and want to thank you for the script. I don't really demand a regex; I just need to replace the SWF reference with the appropriate JPG. I used a regex because I often use GREP in BBEdit. But apparently the implementation in runrev is a bit different. It should be based on PCRE, and that supports this behavior. Might this be a little bug? Whatever the case, I am helped! You noticed the ID was gone in the IMG tag with the JPG. I removed it because I didn't need it. But it's cool with me if it stays in.

RegEx is convenient, but it's able to offer that convenience usually at the price of performance. It almost always takes more lines of code to do the same thing with chunk expressions as one can do in RegEx, but is often much faster. And when someone else writes the code, as you've done here, you get both speed and convenience. :) -- Richard Gaskin Fourth World Rev training and consulting: http://www.fourthworld.com Webzine for Rev developers: http://www.revjournal.com revJournal blog: http://revjournal.com/blog.irv > > > on mouseUp > > put "ID4" into chosen_id > put "ID=" into id_part_uno > put quote&chosen_id"e into id_part_dos > put id_part_uno & id_part_dos into id_target > -- > put fld 1 into v -- original data > put numToChar(255) into z -- arbitrary item delimiter > set the itemDelimiter to z > -- > -- put a marker before and after the image elements > -- to confine them to their own item > -- > put " put ">" into item_stop > replace item_start with z&item_start in v > replace item_stop with item_stop&z in v > -- > repeat for each item i in v > > if id_target is in i then > put "flashblocks/editors/Mediablock.swf" into bad > put "flashblocks/data/resize/home1_holder_txt_IDPLACE_mb.jpg" into good > replace bad with good in i > replace IDPLACE with chosen_id in i > put i after h > end if > > end repeat > -- > -- remove the item separators > -- > replace z with empty in h > put h into fld 2 -- holds output > end mouseUp > ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
Re: How do I use substrings in regular expressions?
Terry,
Here's a somewhat generic script to find any HTML element by its ID and make
the replacements you need. It doesn't use regex. I apologize.
on mouseUp
put "ID4" into chosen_id
put "ID=" into id_part_uno
put quote&chosen_id"e into id_part_dos
put id_part_uno & id_part_dos into id_target
--
put fld 1 into v -- original data
put numToChar(255) into z -- arbitrary item delimiter
set the itemDelimiter to z
--
-- put a marker before and after the image elements
-- to confine them to their own item
--
put "" into item_stop
replace item_start with z&item_start in v
replace item_stop with item_stop&z in v
--
repeat for each item i in v
if id_target is in i then
put "flashblocks/editors/Mediablock.swf" into bad
put "flashblocks/data/resize/home1_holder_txt_IDPLACE_mb.jpg" into good
replace bad with good in i
replace IDPLACE with chosen_id in i
put i after h
end if
end repeat
--
-- remove the item separators
--
replace z with empty in h
put h into fld 2 -- holds output
end mouseUp
I noticed that your jpg image doesn't have an ID attribute. In the above script
the ID remains the same. That is probably a good idea since the ID is embedded
in the jpg name and it would be confusing to have an ID attribute that was
different. You'll need an ID to manipulate it with javascript (which I'm sure
you know).
Hope this at least gives you something to think about.
Mike

How do I use substrings in regular expressions?
I cannot get this regex to work:
put replacetext(textBlock,q("]*) ID='" & idNumber & "'
([^>]*)>"), q("")) into textBlock
The purpose is to replace:
with:
The \2 and \3 part should insert the substrings matching ([^>]*). This is
working in BBEdit, but Rev gave me literally "\2 \3>":
I cannot use the normal replace command, because it should only work when the
ID attribute is matched.
