Using XPath in 2023

Might be interesting to see if JS libraries that do a lot of DOM manipulation could get some perf gains. Maybe they already utilize evaluate?

Domenic Denicola (the man who ruined promises) probably will as well.

• Playwright

  379 61,568 9.9 TypeScript

  Playwright is a framework for Web Testing and Automation. It allows testing Chromium, Firefox and WebKit with a single API.

  

I'm using Playwright [1] (dotnet version) to test my web app, and I mainly use XPath to identify elements on a page. I found it to be to the best choice in my use case, mainly because it is composable. I can define an XPAth to a table `tableXPath` and then reuse it to identify a cell in the table like eg $"""{tableXPath}//td[text()="my value"]""", and I can further reuse that to identify a sibling cell which might trigger an action.

• camaro

  3 547 6.2 JavaScript

  camaro is an utility to transform XML to JSON, using Node.js binding to native XML parser pugixml, one of the fastest XML parser around.

back in the day where every OTA (online travel agent) and airlines use XML for their API, we had to integrate them in an API gateway where to unify their API schema and workflow.

we wrote a small package[1] (using pugixml) to transform XML to JSON using a custom Xpath template syntax. Make our job much easier.

• fontoxpath

  2 125 6.8 TypeScript

  A minimalistic XPath 3.1 implementation in pure JavaScript

  

Not XPath, but for folks interested in querying (rather than walking) syntax trees for arbitrary nodes, this is also a cool feature of tree-sitter[1]. It uses a scheme-like syntax, and it’s impressively efficient.

And in terms of XPath, for folks using a JS stack, fontoxpath[2] supports a DOM facade adapter interface which allows for querying any arbitrary tree-like structure, so it could certainly handle the same use case.
