pakistan_ppra_*: Parse HTML listings?

https://www.ppra.org.pk/api/index.php/api/release,
https://www.ppra.org.pk/api/index.php/api/records and
https://www.ppra.org.pk/api/index.php/api

return 503

Note that if you go to https://www.ppra.org.pk/ and then click:

There is a list of tenders in OCDS format:

But the "download all" button doesn't work.

We could scrape https://www.ppra.org.pk/opendata.asp?PageNo=1 to get the list of links to download, e.g https://www.ppra.org.pk/ocds.asp?id=523047

Looks like they have 87 pages currently: https://www.ppra.org.pk/opendata.asp?PageNo=87

Retrievable in full by software, either by using an HTML page listing bulk download URLs, or by using machine-readable data as the only input.

They don't really pass this one, as we mean a single HTML page listing (with links to bulk downloads).

If we think there's value, however, we can add it.

@yolile Should we remove Pakistan? Scraping links from individual HTML pages seems to be the only way (https://www.ppra.org.pk/opendata.asp?PageNo=1) but that doesn't meet our minimum criteria for inclusion in Collect.

If we remove it from Collect, we can delete the Publication in the registry, since it has never succeeded in obtaining a collection.

Sounds good.

@allakulov, could you inform Carey about this so that we can decide whether to reach out to Pakistan and try to make them fix this?

[allakulov]

I have informed Carey and we are following up with PPRA. I'll keep you posted.
