G'day codewalker,

-- I've downvoted your post because you've made absolutely no effort yourself.

You've been here for about a year and you are well aware that this is not a code writing service. You were last informed of this two days ago: see "Re^2: To make changes in same file in subdirectory in folders by using xslt in Batch file", its Reputation and Corion's response.

PerlMonks is for discussing Perl and helping those who wish to learn. In that spirit, here's some help.

You can remove a substring of known length by using substr with an offset of zero and a negative length:

$ perl -le 'my $x = q{X.xml1.xml.xml}; print substr $x, 0, -9'
X.xml

Another way is with a regex substitution:

$ perl -le 'my $x = q{X.xml1.xml.xml}; $x =~ s/1\.xml\.xml$//; print $
+x'
X.xml
