the braces around
{0,9}
means “where the preceding item appears zero to nine times.”

• Regular expressions are a powerful tool. There are many good topics on regular

in the regular expression syntax used in different tools). We recommend you read
Mastering Regular Expressions
by Jeffrey E. F. Friedl (O'Reilly).
