Question

como eu faço pra saber se o número é par ou impar, para testar um valor e saber se um atributo é par ou impar com xsl?

<table>
    <xsl:for-each select="asd/dsa/item">
    <tr>
        <td>
            <xsl:if test="???????">
                <xsl:attribute name="class">f2</xsl:attribute>
            </xsl:if>
            <p>
                <img src="i_folder.gif" alt="" />
                <a><xsl:attribute name="href"><xsl:value-of select="link"/></xsl:attribute><xsl:value-of select="title"/></a>
                <xsl:if test="description!=''">
                    (<xsl:value-of select="description"/>)
                </xsl:if>
            </p>
        </td>
    </tr>
    </xsl:for-each>
</table>
[edit] consegui assim:
<table>
    <xsl:for-each select="asd/dsa/item">
    <tr>
        <td>
            <xsl:if test="substring(@id, string-length(@id)) = '0' or substring(@id, string-length(@id)) = '2' or substring(@id, string-length(@id)) ='4' or substring(@id, string-length(@id)) ='6' or substring(@id, string-length(@id)) = '8'">
                <xsl:attribute name="class">f2</xsl:attribute>
            </xsl:if>
            <p>
                <img src="i_folder.gif" alt="" />
                <a><xsl:attribute name="href"><xsl:value-of select="link"/></xsl:attribute><xsl:value-of select="title"/></a>
                <xsl:if test="description!=''">
                    (<xsl:value-of select="description"/>)
                </xsl:if>
            </p>
        </td>
    </tr>
    </xsl:for-each>
</table>
