[xsl] Carrying variable value outside for-each loop

[sridhar raman <thotha3 at yahoo dot com>]

Hi,
  I have the following xsl structure.
  <xsl:for-each>
     <xsl:if <condition>>
        <!--set a variable value to "true"-->
     </xsl:if>
  </xsl:for-each>
  <!--would like to use the variable value here-->

But unfortunately, the variable value becomes empty
outside the for-each scope. So what should I do to
have the variable retain its acquired value. Can I use
global variable, if so how?

Thanks,
Sri
