regular expression in Java

[Ye Zhou]

Hi all,

I am trying to convert a perl program into java and I got stuck in the
regular expression part. It seems like java.util.regex couldn't help
much. I checked with Apache regexp and didn't get the right way to do
it either. Therefore, I am writing to see if someone could throw a
light on how to do a translation on the statement below.

if ($xml =~ m/^.*?<Transaction.*?instanceId="(.*?)".*?receiver=" (.*?)".*?sender="(.*?)".*?transactionId="(.*?)".*?/s)
{
return ($1, $4, $3, $2);

Your help is greatly appreciated.

Thanks,
Ye

Try this...

String regex = ".*?<Transaction.*?instanceId="(.*?)".*?receiver=" (.*?)".
*?sender="(.> *?)".*?transactionId="(.*?)".*?";

Pattern p = Pattern.compile(regex);
Matcher m = pattern.match(xml);
if (m.matches())
return new String[] {m.group(1), m.group(4), m.group(3), m.group(2)};
