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

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.
