[antlr-interest] help for URL grammar

[Christian CORMIER]

Hi,
I test https://github.com/yaojingguo/antlr-url-grammar.
domainlabel: alphanum ((alphanum | '-')* alphanum)?;
don't recognize something like www.u-picardie.fr using interpreter of  
last version of ANTLRworks (1.4.2)
But for www.uu-picardie.fr is OK.
Regards
