set oRegExp= new RegExp


RegExp.global=true
str=oRegExp.replace(str,"<a href = mailto:$1>$1</a>")

HOWEVER, the input string in my case may already be converted to the format

do NOT want a replace to take place.  If I run the regexp replace on this,
it will match the email address that is within the html tags, resulting in


match an email that it finds with, say, a ":" in front of it??

just not include the ":" in the match, but still match the rest of the
email.  Any ideas?

Thanks in advance for any feedback!

Off the top of my head, I think that this will do it.

: I am trying to scan a string to see if it contains an email adress.
If it

tag.


all
: that the string would contain, then the following code works fine:
:

kjhsjdkfhksjhfskdjfh "
: set oRegExp= new RegExp

address of

: RegExp.global=true
: str=oRegExp.replace(str,"<a href = mailto:$1>$1</a>")

Unfortunately this doesn't work.  It still finds a match on the email
address, but just doesn't match the beginning "<", so the replace would
still replace where I do not want it to. Hmmm....

Using the above, the replace subexpression becomes $2 instead of $1.

This still doesn't do it.  This one only matches the pure pattern itself,
i.e. it doesn't exclude certain patterns and match others depending on what
precedes it.

RegExp's are wonderfully terse... but sometimes IMO it's a good idea NOT to
do too much in one shot.  Better to keep such high level issues visible in
the code, and think of it as bonus to keep your regular expression more
simple and readable.  The more it different things it tries to do, the more
trouble somebody is going to have changing it later!

Of course there's another rule, "if it was hard to do it ought to be hard to
change". <g>
