where:
• \a\a.Tis the first pattern.
• xxxxxxxxxx;is the second pattern.
• match=1;prestrip=2;is the first match-transformation pair.
• match=2;pre=8;is the second match-transformation pair.
Pattern
Valid Content
The content for a pattern follows the digit map rules of RFC 2705, supplemented by the rules for regular
expressions. Where there is an overlap between the digit map and regular expression rules, the digit map rules
apply. For this reason, there are some special cases, included in the table below.
The following table describes the most common elements. As mentioned, all regular expression elements are
supported.
Element Origin Description
0 1 2 3 4 5 6 7 8 9 Literals Literal digits, used as is.
# * a to z Literals Literal characters, used as is.
Special cases:
• The literal x character is represented by \x.
• The literal t character is represented by \t.
x Digit map rules Wildcard for any single digit, 0 to 9.
\a Regular
expression rules Wildcard for any single alphanumeric character.
[digit-digit] Regular
expression rules A digit within the specified range.
[character-
character] Regular
expression rules A character within the specified range.
[digit1, digit2,
digit3] Regular
expression rules One of the characters in the collection.
. Digit map rules Repeat the last element 0 or more times. For example, xxxx. means repeat the last x 0 or
more times, which means this pattern matches three or more digits (not four or more
digits)! Use of this element results in a pattern with “minimum requirements”.
