xslt pagination

Hi,

I  have some very simple XSLT that I have created, displaying an XML feed nicely.
However, this XML feed can contant hundreds of records so I need to add some pagination to ensure it stays tidy. However, I have no idea where to start.

Any help would be great.

Attached is a snippet of the XML structure.
If you would like my XSLT then I can post that too.

Thanks
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Root>
 <Product Page_Nr="41">¿    
  <Story>¿
   <ServiceName>Test Name</ServiceName>
   <Product_Rating>5</Product_Rating>¿
   <Desc_Destinations>Test Desc</Desc_Destinations>¿
  </Story>
  <Story>
   <Desc_Snapshot>Blah blah blah</Desc_Snapshot>¿
   <Desc_Hotel_Facilities>test facilities</Desc_Hotel_Facilities>¿
   <Desc_Guest_Rooms>92 Rooms • Balcony • Fully equipped kitchen • Air-con • TV • Hairdryer • Iron and ironing board</Desc_Guest_Rooms>¿
   <Price>£118</Price>
   <Desc_Price_description>Superior Suite (Room Only)</Desc_Price_description>¿
  </Story>¿
  <Image_1 href="hotel-image.jpg"></Image_1>¿  </Product>
</Root>

Pagination is just a matter of cutting the page, so usually the XSLT is not very difficult.
You need to pass a parameter to the XSLT that tells you which should be your first record to show, and how many records you want to show.

Rest depends on the (web) architecture you are using

Basically I need more detail.
How do you run the XSLT
And how do you expect this to happen?

Is this static HTML calling an XSLT on an input XML... then javascript and eg. sarissa could do magic
Do you have ASP? Something else

Paging is a piece of cake, but you need to tell us what you want to happen.

Hi Gertone,

Thanks for getting back to me.
I am not using ASP. But probably using HTML to call an XSLT on an XML input then javascript to do the transformation.

Can you show me an example of this working?

Thanks

This should get you started

Make sure that you have a function showPage() in your javascript
that takes two parameters (integers, the first Record and the number of records)
and that does the transform passing the two integer parameters to the XSLT

Of course you could easily add extra navigation, I did a naieve "previous" and "next"
but it is fairly simple to add a "first" and "last"
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    exclude-result-prefixes="xs"
    version="1.0">
    <xsl:param name="first">4</xsl:param>
    <xsl:param name="size">8</xsl:param>
    
    <xsl:template match="Root">
        <div>
            <xsl:apply-templates select="Product[position() >= $first and position() &lt; $first + $size]"/>
            <xsl:call-template name="navigation"/>
        </div>
    </xsl:template>
    
    <xsl:template match="Product">
        <!-- do product stuff here -->
        <p><xsl:value-of select="Story[1]/ServiceName"/></p>
    </xsl:template>
    
    <xsl:template name="navigation">
        <div>
            <a href="_blank">
                <xsl:attribute name="onclick">
                    <xsl:text>showPage(</xsl:text>
                    <xsl:value-of select="$first - $size"/>
                    <xsl:text>,</xsl:text>
                    <xsl:value-of select="$size"/>
                    <xsl:text>);</xsl:text>
                </xsl:attribute>
                <xsl:text>previous</xsl:text>
            </a>
            <xsl:text>   </xsl:text>
            <a href="_blank">
                <xsl:attribute name="onclick">
                    <xsl:text>showPage(</xsl:text>
                    <xsl:value-of select="$first + $size"/>
                    <xsl:text>,</xsl:text>
                    <xsl:value-of select="$size"/>
                    <xsl:text>);</xsl:text>
                </xsl:attribute>
                <xsl:text>next</xsl:text>
            </a>
        </div>
    </xsl:template>
    
</xsl:stylesheet>

Thanks Gertone,

I've downloaded the sarissa package and managed to write some js that is working.
Thanks for your help, very simple when you know how.

Thanks
