remove the <xsl:if/>

>     <xsl:copy>
>       <xsl:apply-templates select="@*|node()"/>
>     </xsl:copy>
> 	</xsl:if>
>   </xsl:template>

and add a further template matching on book:

<xsl:template match="book">
  <xsl:copy>
    <xsl:apply-templates select="@* | otherdetails[@price = '10']"/>
  </xsl:copy>
</xsl:template>

So it's only a further special case in the identity transformation.

Hope this helps,
