Subject: RE: [xsl] Use XSL:Variable From: "Paulo Mendes Pinto" <paulo.pinto@xxxxxxx> Date: Tue, 1 Feb 2005 15:48:42 -0000 |
Hummmm In my CONTROL node I have the Extentions of the file and in my ObjectIndex Node a want to concatenate it to the file name (without extention). I have to put in one variable the value read in the CONTROL node and concatenate with the file name in ObjectIndex Node. Try to explain in Portuguese: No ns de Control tenho definido a extensco dos ficheiros e quando aplico um template ao ns ObjectIndex quero que, ao nome do ficheiro aqui definido, seja concatenado a extensco que foi lida no ns de CONTROL. Falaste que as variaveis sco mais usados para contas matematicas... sera que podemos guardar um valor num template e usar noutro template?
