Filter data when insert

This is more a "pure" XForm question than an Orbeon one, but I'm sure you experts can help me :-) otherwise I would appreciate a hint about where can I ask it.

For inserting optional data in my XForm I have instance called 'template' where I have all possible data (if we forget about the 'choice' case, it is a XML with all the optional data). When I click insert, I copy the corresponding node form 'template' into 'instance'. This is working fine. My question is, how can I filter the data that is copied? So, in certain circumstances I don't want to copy the entire node, I want to skip some children node (based on a certain XPath expression), how can I do it?

For example my 'template' data looks like

<address> ----> Optional Data

<name/>

</address>

<age>

</person>

Let's suppose I have an instance data as

</person>

In my XForm I have a button 'Add Address'. If I click on it, I copy the following node from 'template' into 'instance'

<name/>

</address>

so my instance data looks like

<address> ----> Node added

<name/>

</address>

</person>

For that I execute a code like (not checked)

<xf:insert position="after" at="last()" context="." ev:event="DOMActivate" nodeset="..." origin="instance('template')/person/address"/>

My question is, can I skip for example to copy the node <number/>? So, I would like to copy

<name/>

</address>

and my instance data would look like

<address> ----> Node added without 'number'

<name/>

</address>

</person>

For adding number I will show another button and so on.

How can I do it?

I would need some kind of 'generic' solution, no only for this special case.

Thanks a lot

Re: Filter data when insert

Probably I didn't explain myself very well in my last message :-)

So, let's suppose my 'template' data is something like:

<age/>

<name/>

</number>

</street>

</address>

</person>

where 'isi' is a namespace I use for adding some metadata (so, I shouldn't be posted at the end).

That 'construction' means: address is optional, if you create one, city is optional and number in street is optional, and so on...

My initial instance data looks like

</person>

and the XForms looks like

Person

age : 88 -> Input text with the age

[Add address] -> Button for adding the optional field 'address'

Now, if I press the 'Add address' button I want to add the address node without all the non optional fields

So, I want to select from 'template' the following node:

<name/>

<number isi:opt="true"> ---> Removed

</number>

</street>

<city opt="true"/> --> Removed

</address>

that means:

<name/>

</street>

</address>

After adding it, my instance data would look like:

<name/>

</street>

</address>

</person>

and the XForm would be

Person

age : 88

address

street

name : ________

[Add number]

[Add city]

Is that possible? When I perform the 'insert' action, can I 'filter' the origin node and remove the children node with the @isi:opt='true'?

I guess this is a XPath question and probably can not be done :-(

Thanks a lot

Re: Re: Filter data when insert

Isi,

It is possible but, xforms:insert doesn't have a filter, so you must
do it in a couple of steps:

- first insert the template
- then delete the nodes you don't want from the destination with xforms:delete

You could also:

- copy the template to another instance
- remove the extra nodes there
- then insert the filtered template in the final destination

For simplicity I would go with the first solution.
