Hi monks,
I need some guidance in my program.
I have created a web application tool using XML::XSLT, XML::Smiple and XML::Parser and creating XML out file is working fine but there is a delay in writing the file can any one give me some best idea to rectify it.
Thanks in advance.
Program to create XML files.
