There are minimum length for a property?
Yesterday I sent a question because I didn't get to change a property 
value, but now I check that I can do it if the length of this properti 
is longer than 2 digits, if is 1 or 2 digits the process die when you 
try xmlSetProp. How can i solve this?
Thank you in advence
