Re: [Xsltforms-support] paging through items in a repeat

[<fr...@fl...>]

Hi Peter,

The way I do it is by adding a condition to the repeat nodeset, such as
[position() >= instance('search')/from and position() <=  
instance('search')/to]"

Where 'search' is an instance, specially defined for these 'utility'  
functions.

Then with two triggers, 'previous' and 'next', I allow the user to  
manipulate the from and to values:

<xf:setvalue ref="instance('search')/@from"  
value="if(instance('search')/@from&gt;instance('search')/@number,instance('search')/@from -  
instance('search')/@number,1)"/>

<xf:setvalue ref="instance('search')/@to"  
value="if(instance('search')/@from +  
instance('search')/@number&lt;count(instance('id')/Item),instance('search')/@from + instance('search')/@number -  
1,count(instance('id')/Item))"/>

where @number is the number of items on a page.

Not sure if this is the easiest way, but it works.

Kind regards,

Fred van Blommestein
