> I need a global xsl:variable, is it possible?

yes, just place the xsl:variable instruction ath the top level
ie a child of xsl:template.

<xsl:variable name="global">
  <xsl:value-of select="/the/first/node/you/want"/>
  <xsl:value-of select="/the/second/node/you/want"/>
  <xsl:value-of select="/the/third/node/you/want"/>
</xsl:variable>

Then you can use  <xsl:value-of select="$global"/> in any template
to get the concatenation of the string values of the nodes.
