Advanced Email Parser uses popular Boost Library for operating with regular expressions (RegExp). Regular Expressions use Perl syntax, but not support modifiers in expression only via Regexp Flags

You can find more information about Regular Expressions Syntax on this pages: PerlRe, PCRE

Method

Comparing methods. Match succeeded if the whole string matches the given pattern. Search succeeds if a substring that matches the pattern founded in string.

Result not Begin of Line

When this flag is set then result does not represent the start of a new line.

Result not End of Line

When this flag is set then result does not represent the end of a line.

Result not Begin of Word

When this flag is set then result can never match the start of a word.

Result not End of Word

When this flag is set then result can never match the end of a word.

Dot not Match Newline

Specifies that the expression "." does not match a newline character. This is the inverse of Perl's /s modifier.

Dot not Match Null

Specifies that the expression "." does not match a character null '\0'.

Match Any Results

Specifies that if more than one match is possible then any match is an acceptable result: this will still find the leftmost match, but may not find the "best" match at that position. Use this flag if you care about the speed of matching, but don't care what was matched (only whether there is one or not).

Match Partial Results

Specifies that if no match can be found, then it is acceptable to return a match [from, last) such that from!= last, if there could exist some longer sequence of characters [from,to) of which [from,last) is a prefix, and which would result in a full match. This flag is used when matching incomplete or very long texts.

Match Single Line

Equivalent to the inverse of Perl's /m modifier; prevents ^ from matching after an embedded newline character (so that it only matches at the start of the text being matched), and $ from matching before an embedded newline (so that it only matches at the end of the text being matched).

Ignore Case

Disable case-sensitive search

Use Locale Specific Collation

Uses the default system locale for string comparison.
