Solved
To access the values of the nodes is as follows:
yearmem: = (tree xpath: '// year') first contentString asNumber.
I also edit the other methods of the XMLNode class.
Thanks
Oswall

Hi Oswall
Well, you have located the correct node, which is some kind of XMLNode, so all
you need is to access its content. If you browse the class and look at its
‘accessing’ protocol, you see the method XMLNode>>#contentString, which will
give you, in your test case, ‘2014’ as a string. If you want to enter it in the
database as a number, asNumber will do that’

Hello Peter,
Thanks for your help.
The value I get is:
<year> 2014 </ year>
What I need is to extract the atomic value of the node, which is:
2014
To assign it to variables and create objects. I can not find how to obtain that
punctual value 2014.
The main purpose is to read many xml files and create smalltak objects with
that data, then save them in DB and process the data.

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.
