XSLT match both first and secon child

I've the below XML.

<para><page num="42"/><content-style font-style="bold">2/1/4</content-style></para>

Here i'm creating a template and trying to match both the first and second child as below.

<xsl:template match="para[node()[position() = 2 and self::content-style[matches(., '(\w+)/(\w+)')] and (position() = 1 and self::page)]]">

Here when i try it like

<xsl:template match="para[node()[(position() = 1 and self::page)]]">

or

<xsl:template match="para[node()[position() = 2 and self::content-style[matches(., '(\w+)/(\w+)')]]]">

the match is correctly being called, but when i combine as shown in top, it is not working,

I need to perform some tasks based on this match, please let me know where am i going wrong and how to fix this.

Thanks
