[ops-user] problem of designing

Hi,

I have some doubts concerning the possibilities to develop what I want, so if somebody can tell me if it is possible to do it...

Basically, let's consider only two tags:

A parent tag can contain another parent or a child.

A child tag contains none tag.

what I use is the user to create dynamically his tree:

He starts from a single node: <parent>

with two triggers, he can add a parent or a child under the first parent... and so on.

So the user builds the xml file by inserting (and deleting...) the nodes he wants.

it's a kind of repeat problem, except that I'm afraid I'm to meet binding problems...

Regards,

Marc

Marc,

I believe that with XForms 1.0, this is not possible. XForms 1.1, which
is only a draft, proposes a new "duplicate" action which should allow
such tree construction. But "duplicate" is not supported in OPS right now.

In the meanwhile, you could build the tree server-side, using a
submission with instance="replace": send the instance along with some
information about what node to add, and receive the updated instance,
built on the server with XSLT, for example.

Hi Erik,

thanks for your answer.

I've been working on your idea of using xslt.

what I want to do is building an xml file, from data of a first xml file.

So I build the second file using xslt.

In this file, I want to do:

if "parent" has only "parent" nodes, then input <tag1> and loop.

if "parent" contains only "child" nodes, then input <tag2> and input data from the 1st xml file.

So my problems:

I do not figure out how to make the test on the name of the tag itself...

I do not know how to specify the loop in the xslt language...
