Hi all.
I posted previously on how to move in a tree by a node at a time by using
HTML:TreeBuilder which is used with LWP.
I wish to move by a single node and get the following info:
tag of the current HTML element.
Text of the HTML element.
Attributes of the current HTML element.
Of course,

Hi Shlomi
Thanks for your comments.
In fact, the problem was enirely my own fault and did not exihibit in
the code I published.
More specifically the hash I created in %TiesHash did not use the
correct Key - hence it didn't work.
Get that right and the rest falls into place nicely.

Hi,
On shell, successful command returns exit status of 0.
As a best practice what status value shall a Perl function return.
Going by the fact that Perl function returns the value of last command
