XSL - Break out from a for-each loop

I am having a two <xsl:for-each..... > in my XSL file, one inside another. And inside that 2nd loop, I am checking for a condition using <xsl:if..> and I if the condition is true, then I want to BREAK out of the 2nd loop, so that I will be starting back from first loop.

Is there any keyword available in XSL to break out of a loop ?

<xsl:for-each ..........>

<xsl:for-each ............>

<xsl:if test ="$A = 'a'">

HOW TO BREAK OUT OF THE FOR LOOP ???

</xsl:if>

</xsl:for-each>

Thanks a lot
