REGEX

 

Syntax: @REGEX(S1, S2)

S1 = a string value
S2 = a string value

@REGEX returns True (1) if the string S2 matches the pattern specified by the regular expression in string S1, and False (0) otherwise. This function is similar to @EXACT except it allows ``wildcard'' comparisons by interpreting S1 as a regular expression of the type used in the Find and Extract operations. For more information on regular expressions, see Chapter 9, Shortcuts and Tools.

Examples:

@REGEX(``t.p'', ``top'') = 1

@REGEX(``t.*e'', ``table'') = 1

@REGEX(``t.*e'', ``talk'') = 0

@REGEX(``F[0-9]'', ``F3'') = 1

@REGEX(``F[0-9'', ``F3'') = Error! Missing ]

@REGEX(``a'', ``apple'') = 1

@REGEX(``ab'', ``apple'') = 0
