how to get URLs in memo, delimited text or split?

e.g:

in memo.text :

begin

memo1.lines.text := '

rtadgjkjuouioop hxxp://exmpl.com yyhfhjjj

ijoo hxxp://wxw.exmpl.org iolvb

wxw.exmpl.comiiij

fiuddhity

ftp://exmpl.com

uiufsftgco45788

hxxps://exmpl.com

ggcghj

hxxps://wxw.exmpl.net giiu';

end;

result in memo 2

I mean like this code:

function spliter(const s : string; ts, rs : tstrings) : string;

var

i : integer;

begin

for i := 0 to rs.count - 1 do

begin

if (pos('wxw', ts.strings) > 0) or

(pos('fxp://', ts.strings) > 0) or

(pos('hxxp://', ts.strings) > 0) or

(pos('hxxps://', ts.strings) > 0) or

(pos('hxxp://wxw', ts.strings) > 0) or

(pos('hxxps://wxw', ts.strings) > 0) then

begin

result := '';

blah blah blah

etc

end;

rs.text := result;

end;

on button click

spliter(edit1.text, memo1.lines, memo2.lines);

Use a regular expression instead of multiple compares

 

something like this works great for a URL... (From RegexBuddys library)

\b(https?|ftp|file)://[-A-Z0-9+&@#/%?=~_|!:,.;]*[A-Z0-9+&@#/%=~_|]

But beware, a regex or any sort of compare will never be 100% accurate for a URL because a URL can contain most characters, especially if you are trying to filter spam and the poster is trying to bypass the filter...

OK i'll try it.

how do I in order to get results this way? for s: =

'<a href="' to'">' do

I'm not sure what you asking but if your asking how to match / extract the link in your example ' to' then use a regex again, something like this...

a.?href="'(.+)'"

oh sorry still chaos pharsing html script

if you want to use pos then use it with the '://' string - 4 chars for the beginning and the last '.' + 3 chars for the end per line, this should yield full url. regular expressions would be the best way for this and the more correct way to do it.
