Calcolo numerico in XSL
|
|
Il numero di funzioni trasforma la relativa discussione per numerare. Lo stylesheet 1 di XSL dimostra la conversione di stringa, convertiti che dello stylesheet 2 di XSL i valori booleani ad uno allineare e falso.

Funzionamenti di Arithematic
|
|
La aggiunta, sottrae e moltiplica usa la sintassi comune, vede lo stylesheet 1 di XSL. La sintassi di divisione è meno usuale. “/„ Di taglio simbolo è usato nei modelli ed in modo da la divisione di parola chiave è usata preferibilmente, vede lo stylesheet 2 di XSL. Il MOD dell'operatore restituisce un resto dal troncamento della divisione.

Funzione della stringa
|
|
La stringa di funzione () trasforma tutta la relativa discussione nella stringa. Questa funzione non è usata direttamente usualy negli stylesheets poiché in la maggior parte dei casi è denominata per difetto. Lo stylesheet 1 di XSL mostra gli esempi dei numeri alle conversioni di stringa. Notare i risultati dell'divisioni zero.
