Understanding Basic Regular Expression (BRE) Syntax
The ESI syslog parser supports regular expressions created using the Basic Regular Expression (BRE) syntax described
in this section. BRE syntax consists of instructions—character-matching operators (described in Table 350),
repetition operators (described in Table 351), or expression anchors (described in Table 352)—used to defined the
search or match target.
This section contains the following topics:
l “Character-Matching Operators” on page512
l “Regular Expression Repetition Operators” on page513
l “Regular Expression Anchors” on page513
l “References” on page514
Character-Matching Operators
Character-matching operators define what the search will match.
