Re: Expressions/Rules exchange

Expresso still gives me the error: Nested quantifier *

I just copied and pasted his expression in Expresso and it works fine for me. So you might want to look at your method of copy-n-pasting.

On the other hand his expression is still wrong, but I'm sure he can fix that part for ya.

Now I feel very stupid... are there multple way to copy paste ?
I was just selecting the text from the forum and pasting it in the Express app.



do you have another expression that works?

Re: Expressions/Rules exchange

Expresso still gives me the error:
Nested quantifier *

It's the ignore WS option - expression needs to match white space to work, turn this option off.

RegexBuddy does compile it but it does not match several strings:
movie 2 - 3.mkv
...

Fixed with below, but damn I had a lot of complexity stopping part 3 on it's own as (I was sure you didn't want something like "foo - 3.iso") still smaller solution now:

[noparse]^(?<movie>[^-]*?)(?:[- [])+(??:CD|part|DVD)?(?<part1>0*1)]?)?(?: *(?:CD|part|DVD)?(?<part2>0*2)]?)?(?: * (?:CD|part|DVD)?(?:0*3)]?)?\.(?<ext>[^.]*)$[/noparse]​

Re: Expressions/Rules exchange

Guys, don't get me wrong, I'm glad your helping each other with the regex and all, but movies regex stuff doesnt really belong here. Its fine when its just a few posts, but its been going back and forth for a while now. It's not like theres much else going on in here, so no big deal, but I'd still like to split this off somewhere else.

mfsav2, what are you needing this expression for? I'll move the discussion to an appropriate subforum.

Re: Expressions/Rules exchange

Inker,

Yes please do move this somewhere else, as I stated earlier this should have been in it's own thread.

Re: Expressions/Rules exchange

Inker,
I need this for an NFO parsing application developed in VB.NET mainly focused on Network Media Tanks.

Thank you for your kindness and help, sorry for messing up this tread let me know where is appropriate to start the new one and I will move there.

So we split it off for now. I don't really know what subforum this should go to. If you know let me know. Otherwise we can just leave it here I guess.

Great, thanks Inker.

mfsav2,

I've been testing my expression in post 12 with Expresso, and although it works against all the examples you supplied with a 100% hit-rate. The [ and ] matching is not working properly for CD2 and CD3. The following fixes this but still allow some false positives, this can be corrected but would end up more than doubling the expression size:

[noparse]^(?<movie>[^-]*?)(?:[- [])+(??:CD|part|DVD)?(?<part1>0*1)]?)?(?: *\[?(?:CD|part|DVD)?(?<part2>0*2)]?)?(?: * \[?(?:CD|part|DVD)?(?:0*3)]?)?\.(?<ext>[^.]*)$[/noparse]​

Some positives you might not like:

foo [[[1]2.iso
foo - 1][2 3.iso
foo ]]][[[1 2.iso

Great, thanks Inker.

you have been very kind but I'm still not able to use your expression.

I tried everthing, copy paste from the message, from the reply text, typed it in.

I really feel dumb!

(Attached you have the error image and my XSO file.)

Can you be so kind to send me your XSO? (From expresso save the project and zip it)


Thanks,
Mf

OK I looked at your project - Firstly it was an expresso version 1.0 project (I'm currently using 3.0). Secondly you still had the Ignore white option turned on.

Loaded your project with expresso 3.0.3634.15621 (Performing upgrade on import) and turned off "Ignore white" it works fine. I've also attached my project for for you to try out.

 

[mfsav2]

GREAT!
thank you! I started from the source code of Expresso and do not know why I got only 1.0

In any case it works great, I've changed in:
[noparse]^(?<movie>[^-]*?)(?:[- [])+(??:CD|part|DVD)?(?<part1>0*1)]?)?(?: *\[?(?:CD|part|DVD)?(?<part2>0*2)]?)?(?: * \[?(?:CD|part|DVD)?(?<part2>0*3)]?)?\.(?<ext>[^.]*)$[/noparse]

so that part 3 and 2 go under the same are like for the other RegEx.

I have still one think I do not understand:
if you try those two:
movie 2 - 3.mkv
foo - 01.iso
foo - 02.iso

It is funny as the 3 (for the first one) appears to be Part 2 not Part 1. Is great that the name is detected correctly

foo - 01.iso -> 01 is detected in Part 1
foo - 02.iso -> 02 is detected in Part 2


Is not a major problem but I do not understand why...
