RE: [flexcoders] RegExp searching for [ and ], are they reserved? SOLVED
Ahah! I forgot that the RegExp escape character (i.e., backslash) is
also the AS3 String escape character and therefore requires double
escaping! That's really annoying, isn't it?
That's a good reason to use RegExp literal notation rather than a
pattern String passed to the constructor:
/abc/igm <=> new RegExp("abc", "igm")
/\[abc\]/ <=> new RegExp("\\[abc\\]", "igm")
I didn't actually check that the second one is equivalent, but I'm
pretty sure it is.

i think i figured it out, the [ and ] characters have to be
double-escaped like so
new RegExp("\\[[^]*\\]","igm");

this works when {} are used but not when [] is used, you can see in the
example below- it looks like escaping the [] is affecting the match
(although it works fine in the regex test tool).

i had tried escaping them, below i've pasted an example of my problem- 2

the brackets are escaped, the regex with [ and ] only return the ending

hey all,
i'm trying to do a replace on a string and replace anything in brackets
with something else.
so [this] word would get replaced, however in the regex tester at
gskinner this works fine (it's flex based regex test tool) but in my
local code- i always get unexpected results when my regex expression has
brackets in it.
private var mergeRE:RegExp = new RegExp("\[[^>]*?]","igm");
is there another escape character i need to use, why does flash have a
problem searching for [ and ] in regex?
thanks,
