Preface
This tutorial is about regular expressions as they are understood by AutoIt.
About then AutoIt regular expression implementation
Before and after the PCRE implementation. StringRegExp StringRegExpReplace
Why learn and use regular expressions?
Some simple samples
Using regular classes
Creating classes
Using groups
Collection of working samples
Extracting words:
$a = StringRegExp("Some words to extract", "[\w]+", 3)
_ArrayDisplay($a, "Extracted words")
Extracting lines:
$a = StringRegExp("Some words to extract", "(.*)", 3)
_ArrayDisplay($a, "Extracted lines")
Extracting comments:
Extracting comment groups:
Extracting sentences:
Tested, verified, and working on pretty much any sentences... Needs work on words spelled with punctuation symbols, such as Mr., Mrs. Can be handled prior to regex testing by changed to mister and misses.
-JRowe
Local $a
$a = StringRegExp($data, "(['""\w\d\(\),\;\:\-\@\&\s]+(?:.\w+)?+[\.\!\?])", 3)
_ArrayDisplay($a, "Extracted lines")
Removing html tags:
AutoIt normalize variable declarations:
Collect Global, Local and Dim statements in selected code and create declaration code to be inserted as a group in the file TODO: Not tested!
Local $a
$a = StringRegExp($data, "\s*(Global|Local|Dim)(\s+$\w+)", 3)
_ArrayDisplay($a, "Extracted lines")
