XRegex is an AppleScript library to provide pattern matthing with regular expressions.
You can obtain matched texts and replace these.

use XRegex : script "XRegex"
(*** Using Class methods ***)
-- Obtain first matche
tell XRegex's search("\\d{4}", "1972-01-27")
if it is not missing value then
log capture(0) (*1972*)
log range(0) (*length:4, location:0*)
end if
end tell
-- Obtain all mathes
tell XRegex's search_all("\\d{2}", "1972-01-27")
repeat with a_match in it
tell a_match
log capture(0)
log range(0)
(*19*)
(*length:2, location:0*)
(*72*)
(*length:2, location:2*)
(*01*)
(*length:2, location:5*)

end tell
end repeat
end tell
-- Replace
log XRegex's replace_matches("\\d{2}", "1972-01-27", "xx") (*xxxx-xx-xx*)
(*** Compiling Regular Expression and Working with Instance Methods ***)
-- Simple cases

if it is not missing value then
log (count it) (*2*)
log its capture(0) -- 2020-10-10 : whole match
log its capture(1) -- 2020 : first capture
end if
end tell
end tell
-- Obtain matched all sub-texts
tell XRegex's make_with("\\d{2}")

end tell
log (count matches) (*4*)
tell item 1 of matches

log (count it) (*1*)
log capture(0) (*21*)
set {location:loc, length:len} to range(0) (*length:2, location:2*)
--obtain substring
log substring(loc + 3, len) (*10*)
end tell
-- Replace

log replace("http://www.script-factory.net/index.html", ¬
