Atom/RSS feed error

[irosyadi]

There was a problem with the Atom/RSS feed at /feed.xml. The error message says error on line xx at column 17: Opening and ending tag mismatch: link line xx-1 and entry. The specific line xx with the error can vary from site to site.

I found similar errors in these feeds: https://notes.ole.dev/feed.xml and https://hermitage.utsob.me/feed.xml. But these feeds are fine: https://dg-docs.ole.dev/feed.xml and https://notes.johnmavrick.com/feed.xml.

Interesting. I can't help other than confirm I see this issue too. I haven't dug any deeper other than verifying my garden's feed at https://hive.mod0.org/feed.xml has same error. I've not used/looked at that before and so not a big deal for me yet but is a feature I would like working for some future integrations.

Uninformed thought/no research: I wonder if the difference between working/non-working feeds is triggered by a specific post title/comment that has special characters in it that need to be escaped before being tossed to the generator of the feed.

I looked more closely. In the working RSS, the 'feed.xml' file correctly closes the 'link' tag.

<link href="https://dg-docs.ole.dev/feed.xml" rel="self" />
<link href="https://dg-docs.ole.dev" />
<link href="https://dg-docs.ole.dev/troubleshooting/" />

But, in the faulty RSS, the 'link' tag isn't closed properly.

<link href="https://notes.ole.dev/feed.xml" rel="self" >
<link href="https://notes.ole.dev" >

Interesting. Looping back to learn more about this by playing around and documenting my thought process in case it helps others debug this.

In the the feed.njk template it has four //// for the links like so: https://github.com/oleeskild/digitalgarden/blob/main/src/site/feed.njk#L10

<link href="{{ meta.siteBaseUrl }}{{ permalink }}" rel="self" ////>`

The reason behind using four //// in that tag escaping me. Looking at 11ty's RSS example they have the standard syntax I'd expect of a single / like so:

<link href="{{ metadata.url }}"/>

However, we don't have a feed.xml file we have a feed.njk file, and the .njk means this is a Nunjucks template file. In theory the way to get a trailing / for the tag should just be as simple as putting it directly there in the file and there isn't a need for ////.

I did a few quick tests directly on my site to see if removing the extra /// solved the feed issue. (Running with scissors in my own garden is fun).

When switching to a single / I ended up with none rendered in the final feed.xml. I tried doing // to see if that changed things and still nope. Even tried \/and ended up with just a \ which just caused XML syntax errors.

• ////> becomes >
• ///> becomes >
• //> becomes >
• /> becomes >
• \/> becomes \> an XML syntax error
• / > becomes / > another XML syntax error: XML Parsing Error: not well-formed
• \\/> becomes '\>` another XML error
• ></link> becomes > - hey, what is going on there? somebody is "helping" and I bet that somebody is the culprit for the confusion above.
• /////> becomes /> - *HEY THAT IS WHAT WE WANT -- Is FIVE the magic? Not 1, 2, 3, 4 but 5?"

So yeah, apparently the fix in feed.njk is to for each link tag to have five ///// like so:

    <link href="{{ meta.siteBaseUrl }}{{ permalink }}" rel="self" /////>
    <link href="{{ meta.siteBaseUrl }}" /////>

I just applied the fix suggested by @dayne. The /feed.xml from my digital garden is not throwing errors anymore. There were three lines on the feed.njk file where I added an extra /: 10, 11, and 26.

Hi, it seems that the error is still present. example, this test site that I'm using https://functionalitytest.vercel.app/feed.xml

Eventually, rss works fine by applying the previously mentioned fix
