XML is a cheap DSL

"The lesson I took from this is that a universal data representation is worth its weight in gold. There are exactly two options in this category. In most cases you should choose JSON. If you need a DSL though, XML is by far the cheapest one, and the cost-efficiency of building on it will empower your team to spend their innovation budget elsewhere."

I … I think I fell into a hole.

Said hole seems to be #XML + #XSLT shaped.

XSLT’s ability to translate XML into #HTML and / or plain text … is — in a word —AMAZING to me.

Combine #XPath selection and … WOW!

I feel like this is going to be a game changer for some things that I do. Similar to #regularExpressions were 25+ years ago.

The #DNBLab Workshop at #DHd2026 hammers home the continued importance of #XML despite all the nay-sayers. Yes, one can read and parse catalogue data provided through SRU with #Python but one still has to be familiar with #XPath to do anything meaningful.

The pain of MARC fields, tags, and codes remains … on to the MARC manual and the beauty of field 800 …

Just updated the Go based XML processing repositories:

XML DOM loading and accessing:

XPATH 2.0 (and a bit of 3.1) accessing:

The new kid on the block (experimental!) a new XSLT 2.0 processor:

@brucelawson Not CSS, but JavaScript with some #XPath:

```js
Node.prototype.querySelectorText = function (t) {
return document.evaluate(`.//*[text()='${t}']`, this, null, 9, null)
.singleNodeValue;
};
```

Sorry for the "reply guy" kinda answer, but I just had fun recalling how all this works, and maybe it's actually useful for someone. Likely not a good idea to spam the `Node` prototype in production, though.

This isn't just about our course. It's about keeping XML/TEI processing education alive at DHSI. We need MORE of these courses, not fewer!

Instead of working something productive, I have been fighting with #FreshRSS and its #XPath (scraping) feature to make a working #unifi blog #RSS feed.

After some back and forth with documentation and #AI, I finally have a working version.

Still blown away that they have terminated the feeds (especially for the blog site), and glad that 1.20 version has introduced this possibility with no need to depend on other public or #selfhosted services.

XQuery & XPath users, watch out - i spent a day debugging!

Turns out in BaseX & i think XPath 4 (upcoming), `else` clauses are optional.

This is unexpected in an expression language -

`let $name := if ($p) then get-name($p)
return some-func($name)`

is the same as

`let $name := if ($p) then get-name($p) else ( )
return some-func($name)`

but in a multi-screen if/then/else it’s more likely you just forgot the else() or mismatched some parens.

Ah, #wxpath, because using #XPath was just too easy before 🙄. Now with extra layers of #complexity, just in case you weren't already confused enough by web crawling! 🕸️😵‍💫
