Special characters for regular expressions (Continued)TABLE 12

Character Operation

_ An underscore matches on one or more of the following:

• , (comma)

• { (left curly brace)

• } (right curly brace)

• ( (left parenthesis)

• ) (right parenthesis)

• The beginning of the input string

• The end of the input string

• A blank space

For example, the following regular expression matches on "100" but not on "1002", "2100", and so

on:

_100_

[ ] Square brackets enclose a range of single-character patterns.

For example, the following regular expression matches output that contains "1", "2", "3", "4", or "5":

[1-5]

You can use the following expression symbols within the brackets. These symbols are allowed only

inside the brackets.

• ^ - The caret matches on any characters except the ones in the brackets. For example, the

following regular expression matches output that does not contain "1", "2", "3", "4", or "5":[^1-5]

• - The hyphen separates the beginning and ending of a range of characters. A match occurs if any

of the characters within the range is present. See the example above.

| A vertical bar separates two alternative values or sets of values. The output can match one or the

other value.

For example, the following regular expression matches output that contains either "abc" or "defg":

abc|defg

( ) Parentheses allow you to create complex expressions.

For example, the following complex expression matches on "abc", "abcabc", or "defg", but not on

"abcdefgdefg":

((abc)+)|((defg)?)

If you want to filter for a special character instead of using the special character as described in the

table above, enter "\ " (backslash ) in front of the character.
