Hi all,
Suppose we have a XML file describe products as follow:
<?xml version="1.0" encoding="utf-8" ?>
<store>
    <product>
        <ImageUrl>product1.gif</ImageUrl>
        <Name>Screen</Name>
        <Price>12</Price>
    </product>
    <product>
        <ImageUrl>product2.gif</ImageUrl>
        <Name>Printer</Name>
        <Price>15</Price>
    </product>
    <product>
        <ImageUrl>product3.gif</ImageUrl>
        <Name>Printer</Name>
        <Price>20</Price>
    </product>
</store>
If we want to show 3 products per a line (and suppose we have many lines) as follow:
<table>
    <tr>
        <td>
            ...//product i info
        </td>
        <td>
            ...//product i+1 info
        </td>
        <td>
            ..//product i+2 info
        </td>
    </tr>
    <tr>
        <td>
            ...//product i+3 info
        </td>
        <td>
            ...//product i+4 info
        </td>
        <td>
            ..//product i+5 info
        </td>
    </tr>
..... //product i+n info
</table>

How can we obtain this by using XSLT ?
Thanks a lot !:)

Thanks you very much !
But all products are showed three times .
I wonder if I made any mistakes ?.
Here is my code :
<xsl:stylesheet version = '1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<xsl:template match="store">
<table bgcolor="#DDEEF7" WIDTH="100%" >
<xsl:for-each select="product">
<tr>
<xsl:for-each select=". | following-sibling :: product[position() < 3]">
<td>
....some code displaying product info here...
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>

Yes, you made a mistake. The example I pointed you to starts

<xsl:for-each select="item[position() mod 5 = 1]">
