Re: Re: building a hierarchical classification out of
Hi,

I have been trying the code, and the output it's not that I expect
because the tag subunit is identet inside another subunit like this

</sub-sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>
</sub-subunit>

And there are duplicated nodes

But the use of the key to mark set of block is very interesting.

Thank you.

Seems much easy with keys.Thank you.
