recursion

[coupes]

Hi, it's me again

consider the following .xml :

Code: Select all

<list>

  <item>item 1</item>

  <item>item 2</item>

  <item>item 3</item>

  ...

  <item>item 15</item>

</list>

I want to create a list of the different items, however I only want a maximum of 10 items per page. I could I generate a new page each time I reached 10 items on the current page. I assume I'd have to use a recursive template but I've been looking into it for several hours now and I couldn't find a solution.

Any help would be immensly appreciated.

Thanks in advance,
Coupes

Hi Coupes,

You can use something similar with the following sample:

XML:

Code: Select all

<list>

  <item>item 1</item>

  <item>item 2</item>

  <item>item 3</item>

  <item>item 4</item>

  <item>item 5</item>

  <item>item 6</item>

  <item>item 7</item>

  <item>item 8</item>

  <item>item 9</item>

  <item>item 10</item>

  <item>item 11</item>

  <item>item 12</item>

  <item>item 13</item>

  <item>item 14</item>

  <item>item 15</item>

  <item>item 16</item>

</list> 

XSL:

Code: Select all

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:output indent="yes"/>

  <xsl:template match="list">

    <xsl:for-each select="item[position() mod 10 = 1]">

      <newPage>

        <xsl:apply-templates select=".|following-sibling::item[position() <10]"/>

      </newPage>      

    </xsl:for-each>

  </xsl:template>

  <xsl:template match="item">

    <xsl:copy-of select="."/>

  </xsl:template>  

</xsl:stylesheet>

Result:

Code: Select all

<?xml version="1.0" encoding="utf-8"?>

<newPage>

   <item>item 1</item>

   <item>item 2</item>

   <item>item 3</item>

   <item>item 4</item>

   <item>item 5</item>

   <item>item 6</item>

   <item>item 7</item>

   <item>item 8</item>

   <item>item 9</item>

   <item>item 10</item>

</newPage>

<newPage>

   <item>item 11</item>

   <item>item 12</item>

   <item>item 13</item>

   <item>item 14</item>

   <item>item 15</item>

   <item>item 16</item>

</newPage>

Best Regards,
George

Thank you very much George, I would never have thought of using modulus, sometimes I forget there is such an operator

The code works very well, and the solution is much simpler than I would have thought. Thank you again, this is much apreciated.
