I thought I sent this a long time ago, but I dont see it in my mail reader, so i am sending again: -------------------------------
When I set $target in the following program to an obvious string, I can remove it from any text segment with ease. What I am confused about it why I cannot set $target to and then remove it just as easily. use strict; use warnings; use HTML::TreeBuilder; my $html = '<h1>Blah</h1> hithere <p> <br> <h2>Blah</h2>'; my $element_root = HTML::TreeBuilder->new_from_content($html); $element_root->objectify_text; $element_root->dump; print "\n"; my $target; $target = ' '; # cant be removed.. even with below commented out $target = 'hi'; # can be removed... my @text = $element_root->look_down('_tag' => '~text'); for my $text_node (@text) { my $tmp = $text_node->attr('text'); warn $tmp; if ($tmp =~ m!$target!) { warn 'here'; $tmp =~ s!$target!!g; $text_node->attr(text => $tmp); } } print "\n"; $element_root->dump;
