javascript calling processor information

good morning everybody,

I would like to create a stylesheet, which imports another stylesheet depending on the processor used.

<xsl:stylesheet>
//if processsor is msxsl
	<xsl:import select="stylesheet1.xsl"/> 
//if processor is XALAN
	<xsl:import select="stylesheet2.xsl"/>
</xsl:stylesheet>

How can I accomplish that? Is there a specific javascript I can use?

wbr,
Roman
