printf doesn't work the way you (seem) to think it does. Perhaps you should review the documentation for the format string I suggest you forget about printf and use a normal print: `print $xmlfile " <spirit:library>$proj_name\_lib</spirit:librar +y>\n"; # ^------^ 8 spaces` [download] Perl: perlintro perlretut perldoc Basic debugging checklist Yes, even you can use CPAN PerlMonks: How do I post a question effectively?

You probably want `print $xmlfile ' ' x 8, "<spirit:library>$proj_name\_lib</spirit:libra +ry>\n";` [download] If not, please be more specific.	[reply] [d/l]

Perhaps you want `printf $xmlfile ' %s', "<spirit:library>$proj_name\_lib</spirit:library>\n";` [download] but it is difficult to be sure from your description. Cheers, JohnGG	[reply] [d/l]

Maybe Perl's x operator is of interest to you? Consider: `use strict; use warnings; print ' ' x 8, "<spirit:library>XYZ_lib</spirit:library>\n"; print "12345678^\n";` [download] Prints: `<spirit:library>XYZ_lib</spirit:library> 12345678^` [download] True laziness is hard work	[reply] [d/l] [select]

If this is not what you're looking for, show the exact output you need: `use warnings; use strict; my $proj_name = 'foo'; printf "<spirit:library>%8s\_lib</spirit:library>\n", $proj_name; __END__ <spirit:library> foo_lib</spirit:library>` [download]	[reply] [d/l]

I have shown it as Desired: '8spaces<spirit:library>XYZ_lib</spirit:library>	[reply]

Now that everybody else is commenting, I too recommend that you review how printf is supposed to be called. The correct syntax is: `printf "%8s%s", "", "<spirit:library>$proj_name\_lib</spirit:library>\ +n";` [download] This is pretty obviously not the best way to generate eight spaces. Would using a `"\t"` be completely out of the question?	[reply] [d/l] [select]

This syntax works just fine. But using '\t' is not the best solution as i need some 40 white spaces.	[reply]
