TLDR; Are there any HTML parsing libs for Racket? Do they support "selecting" elements based on a set of conditions (e.g. CSS selectors or XPath selectos)?
Suppose I need to look for a set of HTML elements with certain
conditions in a given URL (i.e. scraping).
Now, I can fetch the contents, easily, using the following:
<pre><code>
(define html-as-string
(url:call/input-url
(url:string->url SOME-URL)
url:get-pure-port
(lambda (in-port)
(port->string in-port))
</code></pre>
However I'm stuck here at the "selection". Normally, one would use CSS
selectors (i.e. jQuery style) or XPath but I'm failing to find the
library in Racket's ecosystem. I tried the approach `(se-path*/list
SELECTOR (string->xexpr html-as-string))` but obviously this is not what
I was looking for: I can't "select" tags (i.e. retrieve the matched
tags) or even put conditions on `SELECTOR`.
So I'm looking for a library which can parse a given string into HTML
and be able to "select" elements out of the HTML document, for example
by using CSS selector syntax --any syntax would do as long as I can
actually select what I want :-)
I'd appreciate any help/hint.
