Re^3: Changing from relative to absolute path

I was trying a simple solution for the problem and didn't think of that... you are right of course and I apologize to the questioner if he tried my suggestion and it failed.

As a question for my personal interest, and not a suggestion for the poster to implement, would something like this work...

s#(<A*.?HREF=")#$1absolutedirectory/#;

thanks,
Neil

Update: I should probably add that I am in no way advocating *not* using the right tools for the job - just interested if I have interpreted the problem correctly now.

No. A few cases where it will not work (assuming `.?` was just a typo for `.?`): Lower case letters for name of tag or attribute. Newline between the tag name and the attribute. Whitespace around the `=`. Attribute value not quoted, or single quote quoted. `<A NAME = "HREF=">`. `<A NAME = "FOO">Blah</A> <A HREF = "fnord.html"> ...`. `<IMG SRC = "math.gif" ALT = "B<A"> ... HREF="foo"`. Since perl 5.6.0, you can parse HTML with a regex. But it's not going to be a simple one, and you are better off using a real parser. Abigail	[reply] [d/l] [select]

You still have problems if the "a" and the "href" aren't on the same line of the file. This is why regexes are such a bad idea for this job - you need to think of so many corner conditions. Just when you fix one, the next one appears. -- <http://www.dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

Thankyou for your patience and continued input to this thread davorg :) You must be sighing in exasperation and rolling your eyes by now but it really is a lot of help to us newbies. I guess I'll try not to start answering unless I'm closer to 100% sure I'm right! Thanks, Neil	[reply]

s#(<A.?HREF=")#$1absolutedirectory/#; You probably want `.?` there, as well as `i` (HTML is not case sensitive) and a `g` (since people seem to be attached to writing really long lines). perlre(1) is your friend.	[reply]
