help with string replace - for doing selective replace

[Prasad S]

Hello

I wish to replace all the characters in a string except those which
are inside '<' & '>' characters. And there could be multiple
occurences of < & > within the string.

e.g. string = "this is an example of <how> many words could be hidden
<under> these characters"

now, from this string all the characters should be searched & replaced
by a certain logic except <how> & <under>

I am accepting the string from a textarea form field and there can be
no or multiple occurences of words within < >

Any help will be highly appreciated.

s = "an example of <how> words <under> these characters"

s = s.replace(/[^<]*(<[^>]*>)[^<]*/g,'$1')

<script type="text/javascript">

Sin="an example of <how many> words <as good as> these characters"

Sout = ""
outside = true
for (i=0;i<Sin.leng th;i++) {
x = Sin.substr(i,1)
if (x=='<')outside = false
if (x=='>')outside = true
if (x=='a'&&outsid e) x = 'Z'
Sout+= x
}
alert(Sout)

</script>

I don't know that this can be done in one line of code. I can do it
in two lines. I'm too busy to write the syntax now, however, here is
my idea.

You can use regular expressions to SPLIT the original string into an
array of strings, splitting by <.*> (in other words, splitting the
string by <how> and <under> in your example, creating 3 substrings).

Then it's a simple replace statement for each substring of the
array.

Can the string be of the form " x < y < z > a > ? ", If so, some record
of depth-of-quote is called for.
