[XSLT]Problemende creation variable node set

Bonjour,

D'après mon livre (xslt fondamental) le code ci dessous devrait marcher :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method='html' encoding='ISO-8859-1' /> <xsl:template name="test"> <xsl:variable name="result"> <first> <xsl:value-of select="'toto'"/> </first> <second> <xsl:value-of select="'titi'"/> </second> </xsl:variable> <xsl:copy-of select="$result"/> </xsl:template> <xsl:variable name="testIt"> <xsl:call-template name="test"/> </xsl:variable> <xsl:template match="/"> <html> <head> </head> <body> <xsl:value-of select="$testIt/first"/> </body> </html> </xsl:template> </xsl:stylesheet>
le but est de récupérer un node set dans la variable 'testIt' avec 2 childs (first et second), mais quand j'essaye de générer le html, cooktop me dit

Citation:

ERROR: Description: Expression must evaluate to a node-set.

-->$testIt<--/first

Ci dessous le log d'xsltproc -v :

Si vous avez une idée.... je suis preneur.

Merci d'avance
