GDOM is the next generation of web-parsing, powered by GraphQL
syntax and the Graphene framework.
Install it typing in your console:
pip install gdom
DEMO: Try GDOM online
You can either do gdom --test
to start a test server for testing
queries or
gdom QUERY_FILE
This command will write in the standard output (or other output if specified
via --output
) the resulting JSON.
Your QUERY_FILE
could look similar to this:
{
page(url:"http://news.ycombinator.com") {
items: query(selector:"tr.athing") {
rank: text(selector:"td span.rank")
title: text(selector:"td.title a")
sitebit: text(selector:"span.comhead a")
url: attr(selector:"td.title a", name:"href")
attrs: next {
score: text(selector:"span.score")
user: text(selector:"a:eq(0)")
comments: text(selector:"a:eq(2)")
}
}
}
}
If you want to generalize your gdom query to any page, just rewrite your
query file adding the $page
var. So should look to something like
this:
query ($page: String) {
page(url:$page) {
# ...
}
}
And then, query it like:
gdom QUERY_FILE http://news.ycombinator.com
