Put a function in an XML field

[Mikuru]

Is it possible to put a function in an XML field?For example i have the following xml file:\[code\]<?xml version="1.0" encoding="utf-8" ?> <prova><prova><continente>Europa</continente> <stato>Italia</stato> <societa>SSC Napoli</societa> <actual>1.09769</actual> <estimate>0.447969</estimate> </prova><prova>....</prova></prova>\[/code\]Is it possible to insert a function into 'actual' and 'estimate' fields which change randomly by a timer the values?Thanks in advance.
