    <num>7</num>

</odd>
</root>

Answer 1

You can idenfify even numbers by the expression:

not($number mod 2)

This returns true() if the number is even, false() otherwise.

Achieving the output you show is trivial using:

<xsl:template match="/root">
    <root>
        <even>
            <xsl:copy-of select="num[not(. mod 2)]"/>
        </even>
        <odd>
            <xsl:copy-of select="num[boolean(. mod 2)]"/>
        </odd>
    </root>
</xsl:template>
