I have a tag in an xml document of:
<DOI>10.6483/ceeec.2012.104.0001</DOI> 
that I want to replace with
<DOI>http://dx.doi.org/10.6483/ceeec.2012.104.0001</DOI>

when the code gets to here
if ($rec =~ /<DOI>(ceeec.*)<\/DOI>)/i)
{
    $doi = $1;
    $doi =~ s/$doi/http:\/\/dx\.doi\.org\/10\.6483\/$doi/;
    $rec =~ s/<DOI>.*<\/DOI>/$doi/;
}

I get the message
Unmatched ) in regex; marked by <-- HERE in m/<DOI>(ceeec\.\*)</DOI>) <-- HERE /
 at changeDOI.pl line 26.

Any advice on the way to properly solve this?
