Question

need an xslt for a collection control that produces the below:

<ul>

<li>{quicklink}</li>

</ul>

<ul>

<li>{quicklink}</li>

</ul>

The key here is to have a count on the items. After the 7th item, it needs to start a new list.

Can anybody help with these one..please and Thanks in advance

It would be helpful if we knew what your input XML document looked like :P Please post a sample of input document (USE CODEBOXES) so we can use it to get your output. Is this XSLT 1.0 ? What processor are you running this on?

<fo:basic-link 
 external-destination="url('http://www.whatever.com')"
 color="blue" text-decoration="underline">
  Webucator
</fo:basic-link>

at as many as you like.

you can put these in tables if you like, they will still be recognized.

as for the after 7 newlist im not sure yet, but you problaly get there using a delimiter and the newlist functions, maybe on a substring?.

Well you haven't been very descriptive in your problem at all. So I have no idea if this will help you, or even it it produces what you want. But this is all the help I can give, it should provide you a method/idea to get what you want.

This is a classic grouping issue, which is especially cumbersome in XSLT 1.0. (If you need more information just do a Google search for 'grouping xslt 1.0' and you'll find lots of examples)

My transformation works on via a recursive call template. The idea is that it gathers up all the fo:basic-link element nodes in the input document and passes them into a call template. Inside this call-template, it takes the first 7 element nodes and outputs them inside a <ul> element node. Then it increases the position to the next group of 7, and calls itself. Once it gets to the last group of 7 items or less, it finishes the recursion and doesn't call itself again. Here's all the documents I used to test, the XSLT and the output.

Input Document (since you didn't provide one)

<links xmlns:fo="http://www.w3.org/1999/XSL/Format">
	<fo:basic-link external-destination="url('http://www.whatever1.com')">Webucator1</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever2.com')">Webucator2</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever3.com')">Webucator3</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever4.com')">Webucator4</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever5.com')">Webucator5</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever6.com')">Webucator6</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever7.com')">Webucator7</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever8.com')">Webucator8</fo:basic-link>
	<fo:basic-link external-destination="url('http://www.whatever9.com')">Webucator9</fo:basic-link>
