Hi Oswall
What sort of failure did you get? It helps with this sort of thing to
execute the code in a playground and inspect the result.
One thing you need to know is that the result of xpath is almost always some
sort of XMLCollection, even when there is only one element. I would expect
the result you want if you write yearmem := (tree xpath:
cardset/card/year) first.
Note that you should not need a slash at the start; xpath starts searching
in the children of the top node.
Also you do not need to give every step of the hierarchy; you can always
skip levels provided the result specifies a unique route to the node you
want. So in this case you can write:
yearmem := (tree xpath: //year) first.
Hope this helps

Regards,
I practice with the example of the book. I can not read the atomic values of
the nodes.
For example, with this piece of the example:
<cardset>
<card>
<cardname lang = "en"> Arcane Lighthouse </ cardname>
<types> Land </ types>
<year> 2014 </ year>
To get the atomic value of the node year and assign it to the variable
yearmem, I do it like this:
yearmem: = tree xpath: '/ cardset / card / year'.
But it fails. How do I get the 2014 value?
Thank you
Oswall

Thanks Franz and Monty. I'm working on it, everything is going very well.
The feedback when I master it.
