roRegex

This object allows the implementation of the regular-expression processing provided by the PCRE library.

This object is created with a string to represent the "matching-pattern" and a string to indicate flags that modify the

behavior of one or more matching operations:

CreateObject("roRegex", "[a-z]+", "i")

The match string (in the example above, "[a-z]+", which matches all lowercase letters) can include most Perl

compatible regular expressions found in the PCRE documentation.

This object supports any combination of the following behavior flags (in the example above, "i", which can be modified to

match both uppercase and lowercase letters):

• "i": Case-insensitive match mode.

• "m": Multiline mode. The start-line ("^") and end-line ("$") constructs match immediately before or after any

newline in the subject string. They also match at the absolute beginning or end of a string.

• "s": Dot-all mode, which includes a newline in the ".*" regular expression. This modifier is equivalent to "/s" in

Perl.

• "x": Extended mode, which ignores whitespace characters except when escaped or inside a character class. This

modifier is equivalent to "/x" in Perl.

Interfaces: ifRegex

The ifRegex interface provides the following:

• IsMatch(a As String) As Boolean: Returns True if the string is consistent with the matching pattern.
