Hi All.
I have read the page and the O'rielly book on PWL. I must be thick or
something. but when I dump the content of the web page into the treeBuilder
via a scaler. Then I try and print the tag. I get:
HTML::Element=HASH(0x41b1074)->Tag ( )
Below is the code extract. I have included the HTML:element and
HTML::Treebuilder modules.
sub download_file {
print "accessing new stream \n";
# content of web page passed to this routine.
my $root = HTML::TreeBuilder->new;
$root = HTML::TreeBuilder->new_from_content($_[0]);
#scan_for_non_table_text($root->find_by_tag_name('h5'));
scan_for_non_table_text($root);
$root->delete; # erase this tree because we're done with it
return;
} # end sub
sub scan_for_non_table_text {
my $element = $_[0];
#return if $element->tag eq 'table'; # prune!
foreach my $child ($element->content_list) {
if (ref $child) { # it's an element
print "This is an element\n";
print "$child->Tag ( )\n";
scan_for_non_table_text($child); # recurse!
} else { # it's a text node!
my $text .= $child;
print "text node: $text\n";
}
}
return;
}
I can get the text. But not the name of the Tag or Attributes. I am starting
at the top of the tree. The sub routine naming is screwed because I have
done so much playing around and haven't fixed things up.
So whatam I doing wrong?

Links won't break in proper mailers if you enclose them in <>
