Hi,
I need a regex to match an alphanumeric string with letters and numbers. example: 48HQZBF404TY2298D1414BB8050022YQ3872444 The pattern is defined as: A sequence of alphanumeric characters, letters are upper or lower case, at least 30 chars long, containing at least 10 numbers. This part is easy enough: [a-zA-Z0-9]{30,} But I can't figure out how to match only ifthe string contains at least 10 numbers. thanks, JC
