I haven't created a method to do this yet because pcre doesn't include such
a mechanism natively, but it's certainly possible. Here's some
pseudo-code, which should at least compile. I had to add the extra 'and
subj <> ""' test because at least in my copy of gb.pcre, there's a bug
where if you pass it an empty string it throws an error as if you passed
it a null string. I'm building the latest Gambas now to see if Benoit
fixed that when he fixed the rest of my bad code in 2.7.0. ;)
function FindAll(subj as string, pattern as string) as String[]
dim re as Regexp
dim matches as new String[]
re = new Regexp(subj, pattern)
do while re.offset >= 0 and subj <> ""
matches.push(re.text)
if len(subj) > len(re.text) then
subj = mid(subj, re.offset + len(re.text) + 1)
else
subj = ""
end if
if subj <> "" then re.exec(subj)
loop
return matches
end
