how to use xsl variable
Hi,
    The following should work for you:

	<xsl:param name="fileExtn">
	     <xsl:value-of select="/CONTROL/ObjectFormat[1]/@FileExtension"/>
	</xsl:param>

	You can then use the param $fileExtn anywhere you want.

   Params are like variables. Only variables are more like constants(:->)

Regards,
Omprakash.V

Obrigado Antsnio.

Something I've learn from you response: I have to define my variable in /
and not in template.

If someone can post here examples of use of variable defined as global,
assign in one template and  used in another, that will be nice.

Tkx in avance

Realmente ter tugas nestas listas i sempre interessante.... um abrago
