A better solution is to use two different template rules for the two cases:

<xsl:template match="book[count(title) &lt; 2]">

</xsl:template> 

<xsl:template match="book[count(title) >= 2]">

</xsl:template>

However, I'm not clear from your description exactly what you want the two
different cases to output. Your XML structure seems a bit odd - can one book
really have two titles?
