RegEx

Our MBS Xojo RegEx Plugin provides an alternative RegEx class to Xojo with a few differences to the built in class:

• Better handling of text encodings.
• Much faster Replace/Replaceall operations.
• More options to configure.
• Multithreading support.
• Can work on String and Memoryblocks.
• Dynamical limit of subpatterns.
• Info functions to query details on generated state machine.
• More recent PCRE library version.
• Disassemble function to debug pattern.
• Full unicode support including using unicode escapes.

PCRE2

The newer PCRE2 library offers better performance and a modern API.

• Written for UTF-8 encoding.
• Much faster Replace/Replaceall operations.
• More options to configure.
• Full unicode support including using unicode escapes.
• Just-in-time compiler.

Example

Use PCRE2 to compile a pattern, do a match an inspect result:

Dim Compiler As New PCRE2CompilerMBS

// find numbers
compiler.Pattern = "(\d+)([$€£]?)"

Dim code As PCRE2CodeMBS = Compiler.Compile

// prepare reuable match object
Dim Match As New PCRE2MatchDataMBS(code)

// now run a match
Dim Text As String = "Täst 1234€ Case"
Dim n As Integer = code.Match(Text, match)

// get result found
Dim TotalSubString As String = match.SubString(0)
Dim SubString1 As String = match.SubString(1)
Dim SubString2 As String = match.SubString(2)

break // see debugger
