Subscribing to Forward using FreshRSS's XPath Scraping

2023-03-28

As I've mentioned before, I'm a fan of Tailsteak's Forward comic. I'm not a fan of the author's weird aversion to RSS, so I hacked a way around it first using an exploit in webcomic reader app Comic Chameleon (accidentally getting access to comics weeks in advance of their publication as a side-effect) and later by using my own tool RSSey.

But now I'm able to use my favourite feed reader FreshRSS to scrape websites directly - like I've done for The Far Side - I should switch to using this approach to subscribe to Forward, too:

Screenshot showing RSS feed items: recent Forward episodes including their numbers, titles, and publication dates.

Here's the settings I came up with -

Feed URL: http://forwardcomic.com/list.php
Type of feed source: HTML + XPath (Web scraping)
XPath for finding news items: //a[starts-with(@href,'archive.php')]
Item title: .
Item link (URL): ./@href
Item date: ./following-sibling::text()[1]
Custom date/time format: - Y.m.d

Annotated screenshot showing how each XPath directive maps to each part of the page. The item selector finds each hyperlink that begins with "archive.php" (notably missing the most-recent comic at any given time, which is found at index.php), and the date is found in the text node that immediately follows it, in a slightly-unusual variation on ISO8601.

I continue to love this "killer feature" of FreshRSS, but I'm beginning to see how it could go further - I wish I had the free time to contribute to its development!

I'd love to see a mechanism for exporting/importing feed configurations like this so that I could share them more-easily, for example. I'd also be delighted if I could expand on my XPath rules to load pages referenced by the results and get data from them, too, e.g. so I could use an image found by XPath on the "item link" page as the thumbnail image! These are things RSSey could do for me, but FreshRSS can't... yet!
