Regular Expressions

Regular expressions can be used to search traffic for complex patterns in the data.

The IBM® Guardium® implementation of regular expressions conforms with PCRE. This information does not provide a comprehensive description of how regular expressions are constructed or used. The important point to keep in mind about pattern matching or XML matching using regular expressions is that the search for a match starts at the beginning of a string and stops when the first sequence matching the expression is found. Different or the same regular expressions can be used for pattern matching and XML matching at the same time. For more detailed information, see the PCRE web site: https://www.pcre.org/
