  2. Here’s an approach:
    If you need to open one file at a time, you could glob all the required files in one shot such as:

    @files = glob("ngc*.xml");


    opendir(DIR, $path);
    @files = grep { /^ngc*\.xml$/ } readdir(DIR);

    and then you would use a foreach loop to open individual files:

    foreach $file (@files) {

    I have not compiled or tested the code above. But you get the idea.

  3. Im off to sleep myself, but just for future answerers, please specify what you mean by adding a dircetory, since at least i didnt really figure out what you were meaning with that.

    But if you meant if you can open for example a file from C:somethhing/something, then yes, it is possible. and not sure, but i think you had the right kind of way on taht example, but could be different for that beginning C:.

    Also notice that theres chance that your perl program might not be able to do that right away and might require something like "file:C:" if its aimed for webpage programming only.

    Or it might require you to start it from "Command" for it to right way go finmd the C:, and especially if you are running that program from a website, then if you use C:. it wil lrefer to that servcers C: harddisk, and you shouldnt have right to access that.

    So in case trying to acces your harddisk thorugh wewbpage, i guess it would be something like "local://C:/something/something.stg"

    But i trust better guys answer more accurate, i dont eeally remember any of these right waway, so mostly just guessing.
