Please update documentation to have an example of how to use $obj->pos() to have $obj->insert_element() insert a new HTML::Element object as the first child of a parent, rather than the last child. For example, how to insert: my $obj = HTML::Element->new('meta', 'charset' => $charset); as the first child of the <head> tag, rather than the last. Please hit reply also and let me know how to do this. Thanks. -- Love feeling your best ever, all day, every day? Click http://RadicalHealth.com for the easy way!

insert_element doesn't work that way. It's intended as a convenience method when building a tree from a stream of parsing events. The pos() indicates which element the new one gets appended to, not the position among that element's children (it's always the last child). I think you're looking for the unshift_content method. my $obj = HTML::Element->new('meta', 'charset' => $charset); $html->look_down(qw(_tag head))->unshift_content($obj); Or just $html->look_down(qw(_tag head))->unshift_content( [ meta => { charset => $charset } ] );
