Trend Micro InterScan Messaging Security Virtual Appliance Administrator’s Guide 14-18 Boundary Matches EXPRESSION DESCRIPTION ^ Beginning of line $ End of line Greedy Quantifiers EXPRESSION DESCRIPTION R? Matches R, once or not at all R* Matches R, zero or more times R+ Matches R, one or more times R{n} Matches R, exactly n times R{n,} Matches R, at least n times R{n,m} Matches R, at least n but no more than m times R is a regular expression. Trend Micro does not recommend using ".*" in a regular expression. ".*" matches any length of letters and the large number of matches may increase memory usage and affect performance. For example: If the content is 123456abc, the regular expression ".*abc" match results are: • 12345abc • 23455abc • 3456abc
• 456abc • 56abc • 6abc • abc Common Policy Objects In this example, replace ".*abc" with "abc" to prevent excessive use of resources. Logical operators EXPRESSION DESCRIPTION RS R followed by S (concatenation) R|S Either R or S R/S An R but only if it is followed by S (R) Grouping R R and S are regular expressions Shorthand and meta-symbol eManager provides the following shorthand for writing complicated regular expressions. eManager will pre-process expressions and translate the shorthand into regular expressions. For example, {D}+ would be translated to [0-9]+. If a shorthand expression is enclosed in brackets (example: {}) or double-quotes, then IMSVA will not translate that shorthand expression to a regular expression. SHORTHAND DESCRIPTION {D} [0-9] {L} [A-Za-z] 14-19
