Trasformare xml via xslt

[f0/\/2!3]

Il mio problema è questo: ho un file xml che mi restituisce dei valori in un attributo e un altro file xml dove cambiare altri valori di attributi di conseguenza in certi punti. Pensavo ad un passaggio via XSLT ma non so bene come posso usarlo...

Vi posto un pezzettino dei file per cercare di fare chiarezza:

Primo file xml: mi interessa il valore dell'attributo posizione.
[...]
<sezione posizione='1'>
<corsia posizione='1' nAuto='0' nTir='1' >
<veicolo ID='403' vMedia='80.00' currentV='80.00' enter='0' exit='0' type='tir'/>
</corsia>
[...]

Secondo file xml o file di output: a seconda del valore nel file precedente devo cambiare il valore dell'attributo translation.

[...]


Come fare?

Mi spiegate perchè XMLSpy mi dice che la funzione Incrementa non è un XPath valido??? non ne posso piùùùùùùùùùùùùù non è xpath è ovvio che non sia valida ma da quanto ho visto in giro si richiama così!!!
