Incorporating an array into a regex	Can't Post

For a regex like this:

$linecont =~ s/<au image full(\d{1,3})([^>]*)>/<img src="$full[$1]"$2>/gi;

I believe I'd get an error for having '$full[$1]' in the regex. Is there a way to incorporate the array without resorting to if..then statements. If not, what is the best way to do what I intend to do?

Thanks in advance.

Just put a backslash in front of the [ character.

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>

s/(foo)(bar)/$1\[$2]/;
</pre><HR></BLOCKQUOTE>

are you sure about that?

Assuming $1 equaled 12,
<img src="$full\[$1\]"$2>/ would actually return the contents of $full[12]?

Thanks for replying.

I'm sorry, I totally misread your question. Your method is perfectly fine.
I suggest you try it.

<BLOCKQUOTE><font size="1" face="Arial,Helvetica,sans serif">code:</font><HR>

s/(\d+)/$array[$1]/;
</pre><HR></BLOCKQUOTE>

is perfectly fine.
