xmltodict VS lol-html

Your Cloud Function would be written in Node.js, Python, Go, Java, C#, Ruby, or PHP; pick the one you're most comfortable with. It would get the name and bucket of the newly uploaded XML file as an input parameter. It would then load the file and call a library that makes the conversion. Example libraries: xml-js (for Node), xmltodict (for Python).

Go with xmltodict. Works pretty fine, and you just have to drop any key begining with @ or # (if there is not already an option for that).

Nope, sorry, it's just an XML generator. The Python stdlib offers https://docs.python.org/3/library/xml.etree.elementtree.html and PyPI offers https://github.com/martinblech/xmltodict for parsing, and you could write CSV with csvwriter or pandas.

xmlstarlet is really nothing like jq, as a language. But yes, I use it because it is the best commandline xml processor I'd found. That's the only similarity to jq.

Is this the yq? https://kislyuk.github.io/yq/ It does contain an 'xq', as a literal wrapper for jq, piping output into it after transcoding XML to JSON using xmltodict https://github.com/martinblech/xmltodict (which explodes xml into separate JSON data structures).

This is a bash one-liner! But TBF it really is a 'jq for xml'. I think it would be horrible for some things, but you could also do a lot of useful things painlessly.

Super-easy, take a look at xmltodict https://github.com/martinblech/xmltodict xmltodict.parse(xml_str) gets you a dictionary

So I'm doing some web scraping in Rust, and so I will need to parse HTML. [scraper](https://docs.rs/scraper/latest/scraper/) (which uses [html5ever](https://github.com/servo/html5ever)) is doing fine except that it's the bottleneck of my application.

So I need a faster parser. I've tried [tl](https://docs.rs/tl/latest/tl/) which would've been perfect except that it doesn't actually work on the HTML I have. When I try to `query_selector` the elements I need, it returns nothing.

[Kuchiki](https://docs.rs/kuchiki/latest/kuchiki/) is abandonded.

I couldn't figure out how to get [lol-html](https://github.com/cloudflare/lol-html) to work for me (it's designed for re-writing HTML, whatever that means). It doesn't seem to have an API to extract the inner text of an element.

[html5gum](https://github.com/untitaker/html5gum) seems to be just an HTML tokenizer, or otherwise just too low-level. I have not yet tried [quick-xml](https://github.com/tafia/quick-xml/) but judging from the README, it's pretty low-level too. I mean, if these are the only options left then I will try them. Otherwise, I would love to use a parser that's faster but as ergonomic as `scraper` or `tl`.

At this point, I would be happy with an Lxml bridge/port of some sort. I don't need to mutate HTML, just parse and read data from it.

I'm also in the Workers org but I have had a bit of interaction with Rust. There's some Rust in the Workers runtime using lol-html for HTMLRewriter as well as some tooling and there's the full blown workers-rs framework that I work on, but that's about it for the Rust I work on regularly.

Thanks again and happy to answer any questions! My current unreleased Rust projects include a web crawler that uses Tokio + Tokio Console + Reqwest with this crate for robots.txt and a fast text extraction library using lol-html that I am planning to sprinkle with some minimal ML to get Readability.js style intelligent extraction (with training in Python). See Fathom for an example of the ML approach I'll likely take.

I’d like to see a tool using lol-html [0] and their CSS selector API as a streaming HTML editor.

Cloudflare has open sourced lol-html, a "Low output latency streaming HTML parser/rewriter with CSS selector-based API". Is that what you are looking for?
