You will get this to happen automatically when you use xsl:apply-templates:

<xsl:template match='Theatre'>
    <xsl:apply-templates select='actor'/>
</xsl:template>

(I'm assuming that "actor" elements will be immediate children of "Theatre"
elements, but it's not much harder to handle them being at any depth).
