Sorry. These pull requests were created while my account was flagged by github. The Checks and Copilot summary were not working. Hence, I decided to recreate them.

[Grub4K]

copilot summary can be ignored (its honestly quite pointless) and I will manually approve the workflows. As long as pushing to the old branch works, feel free to keep doing that

[Grub4K]

Note that I had to manually approve the workflows for this PR as well

[SirElderling]

Thanks @Grub4K for the clarification.

How about something like this:

Suggested change

	'uploader': self._search_regex(r'<p\sclass=\"name.+Channel\">([^<]+)<', webpage, 'uploader'),
	'channel': clean_html(get_element_by_class('name', details)),
	'uploader': clean_html(get_element_by_class('creator', details)),

with

details = get_element_by_class('details', webpage) or ''

Potentially, the channel_url and uploader_url could also be extracted, as these can also differ.

[SirElderling]

I did a couple of changes, and added the channel_url and uploader_url as you suggested.

[seproDev]

I think both channel and uploader should be added as they can differ as seen here.

[SirElderling]

Thanks for the example @seproDev . I added the channel extraction as well, since the information was already there.

1. all of this "details" extraction should be moved down near the return for better code flow/readability
2. uploader_path and channel_path are currently fatal because get_element_html_by_class can return None and throws when its html input is None
3. matching base_url in _VALID_URL is overkill, we can always just use https://www.bitchute.com
4. use utils.urljoin
5. move duplicated code into a function

        details = get_element_by_class('details', webpage) or ''
        uploader_html = get_element_html_by_class('creator', details) or ''
        channel_html = get_element_html_by_class('name', details) or ''

        def construct_url(html):
            path = extract_attributes(get_element_html_by_class('spa', html) or '').get('href')
            return urljoin('https://www.bitchute.com', path)

        return {
            # ...
            'uploader': clean_html(uploader_html),
            'channel': clean_html(channel_html),
            'uploader_url': construct_url(uploader_html),
            'channel_url': construct_url(channel_html),
            # ...
        }

[SirElderling]

Thanks for the suggestions @bashonly . I applied those and reverted the base_url change.
