Howto switch two elements in a repeat

Hello all,

I'm trying to switch the position of two elements in a simple list...
Let's say I want the 3rd to become the 4th, and respectively.
With the ignored @at on the insert (anybody knows why?) it seems quite impossible...

Lets say my instance is:
<page>
<list>
<item>
...
<item>
</list>
<list>
...
And so on

In my repeat matching "list" I have something like :
<xforms:insert nodeset="item[5]" at="4" position="before" ev:event="DOMActivate"/>

It will just double item 5 to 5 and 6

Just in case it matters, I'm in a "separate context"
Many thanks in advance, any help will be much appreciated.

Regards,

Alban MAILLERE

Re: Howto switch two elements in a repeat

Isn't the @nodeset supposed to be pointing at the collection of all items
instead of just the fifth? In other words, did you try nodeset="item"?

Besides that, you probably need do to an xforms:delete too as an xforms:insert
will always create a new element.

RE: Re: Howto switch two elements in a repeat

Sure jeroen, i'll delete an item after the insert for the switch ... I'm just trying to insert at the right position for now (shouldn't it be easy?...)
For the @nodeset, the least I can say is that its behaviour isn't obvious. Ops doesn't seem to manage it the "usual" way as long as the @at is ignored.
I am only wondering how I can insert an item from a liste at any index I want in this list.
Any method I tried only allowed me to insert this item before or after itself...

Hi,
I think using the XPath number() function in the @at will work, which will
convert the string 4 into a XPath type number type.

@at is not ignored.

@at is the position within the node-set pointed to by @nodeset. In
your example, the node-set contains only one element, so its size is
1. There is no 4th position in a node-set of only one element. As
suggested, you need @nodeset="list".

> It will just double item 5 to 5 and 6

Which is the expected behavior.

RE: Re: Howto switch two elements in a repeat

Ok it worked this way ... Many thanks Erik and Jeroen for the great explanations
I just mislead myself using nodeset="." (my list tag) instead of "./*" (my actual list of items)

Alban

@at is not ignored.
