Hi dear all, I have written a script which reads the data lines and when a blank line is found all the data up to the previous line is considered as a one set and new set is started after the next line. Then I subtracted from one element of the last line of that set the same element of the first

WSDL issues

Hello, I have trying to use SOAP::Lite with SOAP::WSDL but an running into an issue with the WSDL file I think. If I use SOAP::Lite alone, when I try to call a method, no matter how many parameters I pass it, only the last one is sent to the server ? When I use SOAL::Lite with SOAP::WSDL it

backreference in regexp

Hi all, I see some codes as following my $regexp= "(([gatc]{3})\\2{3,})"; my $string=~/$regexp/; What is the meaning of {3,} of in \2{3,} ? I know \2 is a backreference here but not sure {3,}. I check the camel book and some perldoc but I can't find answer. Thanks, Li

Re: Package clashes

A quick update on this. A grep of the file show: $ifdoff = _process_ifds($info,$fh,$page,0,$byteorder,$ifdoff); sub _process_ifds { process_ifds($info,$fh,$page,$tagsseen,$byteorder,$value_offset); Notice the missing underscore on the last call. Once it was added the package worked fine

Odd. I just tried the same code snippet and it worked fine. You might try putting a space before and after your "=" signs. I don't know if that makes a difference, but it won't hurt. Marc Sacks [EMAIL PROTECTED] D. Bolliger wrote: elite elite am Montag, 25. September 2006 22:27: I not s
