Hi list,

For many hours now I tried to construct a regular exprsession to verify that a string:

Is divided in substrings of maximum 8 characters (qualifiers) separated by a dot '.'
All first characters of a qualifier should be alphabetic the others alphanumeric
The first qualifier can not contain '' or '%'
The remainig qualifiers may contain '' and '%'

Any help would be greatly appreciated.

/^[^\.*%]{1,8}(\.[^\.]{1,8})*$/

Something like this can give ideas...

var testString="4644jkljkj.4euu56.yuiyy45"
var textResult=testString.replace(/[^.]+/g,function(a){
     if (8<a.length) return '\n'+a+' to long substring';
     if (!(/^[A-Za-z]/.test(a))) return '\n'+a+' incorrect first character';
     return '\n'+a' ok !';
})
alert(textResult)

Of course tests can be improved. For example alphabetic characters can be defined as [^\W\d%]+ (which is alphanumeric without and %).
