Hi there, Im new to perl and I dont know how to word this question properly in 'perl terms' but here goes. I have a flat file (tab delimited) and the first line is column headings and the rows after that are data that match the column headings. I want to selectively pull out columns of data based on what column headings are needed (from the prvious html page) and then print it out. pretty straight forward i thought. i hope you can tell me what areas i need to look at to make it do this efficiently. The file I am parsing is quite large - about 2000 rows. any wisdom is greatly appreciated, thanks Aussie.
