Re: Using regexps to parse an XML DTD file

Not what I would do ($1 is not neccesarily a good thing ;-)), but here's some code that works, note that it's not all a regex :-)

$string = "<!ELEMENT ORDER    (NAME,DELIVERY,PAYMENT,ORDERNUMBER)>";
$string =~ m/\((.*)\)/;
@array = split (/,/,$1);
foreach (@array){print "$_\n"}

Excellent, thanks - out of interest though, can it be done with a single regexp? Nick.	[reply]

A single regex cannot generate a variable number of backreferences. What do you think this is, Java? ¹{grin} -- Randal L. Schwartz, Perl hacker ¹The Java regex library I saw caused `/(\w+)\s+)+/` to generate a variable number of backreferences, making it impossible to know exactly what part of the match you were looking at. Evil. They just don't get it.	[reply] [d/l]
