What is this?

A tool which allows you to select items from xast trees using CSS-like queries.

This is a very naive port, so there's still a lot of HTML-specific logic included that could be removed to improve the size and efficiency of the program.

Caveats

One thing to watch out for is that it's much more common to find <namespace:tagname/> style tags in XML. Make sure you escape the colon

const node = select('namespace\\:tagname', tree)

This is also something that could be improved in the future as pseudo-class selectors are not really necessary in generic XML, but I want to keep the API as similar to hast-util-select as possible for the time being.

When should I use this?

You are doing something low level with xast trees.
