NS4: undisputed king of bad browsers. Wouldn't touch it with a 40 ft
pole:p. That said, I do keep a copy around for testing purposes. Not sure
what function you're referring to, however. There's a 'parse anchor'
command, but that's for resolving relative paths (I've already written a
vanilla function for this; it's pretty simple really).
Writing a vanilla routine to extract a base URL (by which I assume you're
meaning protocol + domain [plus username and password, if any]; do correct
me if I'm wrong) should be pretty trivial; something like:
on extractBaseURL(theURL)
try
set oldTID to AppleScript's text item delimiters
set AppleScript's text item delimiters to "/"
if theURL's text 1 thru word 2 contains "://" then
set baseURL to theURL's text 1 thru text item 3 & "/"
else
set baseURL to theURL's text item 1 & "/"
end if
set AppleScript's text item delimiters to oldTID
on error eMsg number eNum
error "Couldn't extract base URL: " & eMsg number eNum
end try
return baseURL
end extractBaseURL
set theURL to "
ftp://ftp.mozilla.org/pub/chimera/releases/chimera-0.4.dmg.gz";
extractBaseURL(theURL)
--> "
ftp://ftp.mozilla.org/";
[I can't absolutely vouch for the above, since I'm not an expert on URL
structure (anyone see if I've missed anything?). Not a very good name
either, I suspect... any webheads have better suggestions?]
This is all much simpler than the pulling of URLs from a larger string that
also contains non-URL text, mind you, which is what I assume Arthur was
asking about (though I may be mistaken... the original question was pretty
vague).
