( #3333=superdoc: print w/replies, xml ) Need Help??
You could use a CPAN module, such as XML::Twig. The following code unconditionally replaces the text of all instances of 'count' elements with the value 14.
use strict; use warnings; use XML::Twig; my $xmlStr = <<XML; <project> <run_count> <count>13</count> </run_count> </project> XML my $twig= new XML::Twig( PrettyPrint => 'indented', twig_handlers => { count => \&count } ); $twig->parse($xmlStr); $twig->print(); exit; sub count { my ($twig, $cnt) = @_; $cnt->set_text(14); } __END__ <project> <run_count> <count>14</count> </run_count> </project>

Side note: Welcome to the Monastery. In general, it is better to use 'code' tags instead of 'pre' tags when posting code. (see Perl Monks Approved HTML tags)
