Some entries doesn't load `metadata` properly

[Rakambda]

Sometimes, some feed entries doen't display properly and are skipped by the plugin.

Example : https://www.reddit.com/user/neo3dofficial/submitted/.rss?sort=new
At some point this error happens (NO METADATA is a log I added in the isValid method) :

If I make the metadata regex a bit more tolerent with #(?P<metadata>\s+submitted.*</span>)#, the error is gone.
This allows the entry to actually be processed by the transformers and the image inlined. Before, as the error happened, the entry was skipped from going through the processors.

However this doesn't seem to handle all cases.

With this feed, even if I have the regex modified, some entries failed to match (though image was already added by the BeforeInsertProcessor) :

I have to say I don't really understand that one, using an online checker the regex seems to match https://www.phpliveregex.com/p/JSm

Thank you for the report. I'll look into that.

I was trying to download the XML file from the RSS feed. But for some reason my wget command does not work anymore. Do you happen to have either a working wget/curl command or the files? The former is preferred since I could reproduce that.
Thank you

Here you go, I just renamed them as .log otherwise Github doesn't accept the .xml

neo3dofficial.log

Thank you. Do you have a way of downloading them? I'll be interested since I am hitting 403 errors when using wget.

[couchoud-t]

Just opened them in the browser and saved the page 😄

[aledeg]

You're lucky. When I am doing that it enters in an non-ending loop of downloading atom files.
I need to figure out what this is about.

Is the fix #15 is a solution to your problem?
