Re: GJS : How can I use Regex ( parse HTML ) ?

[Anastasios Lisgaras <tasosnumberten yahoo gr>]

Unfortunately, because I don't have autocomplete, I have been struggling
with the correct/permissible use of the "match" or "matchAll" function.
I repeatedly made the following mistake :
"Javascript JS ERROR: TypeError: mystr.matchAll is not a function"

Eventually I used the global RegExp from JavaScript  with this bad code:

let tableOfAnnouncementsHTML = announcementsHTML.match(/<table
class=\"table announcements-table\">(.*)\.(.*)<\/table>/);
var announcements = [];

tableOfAnnouncementsHTML[0].replace(/[^<]*(<a
href="([^"]+)">([^<]+)<\/a>)/g, function ()
{
  announcements.push(Array.prototype.slice.call(arguments, 1, 4));
});


It is compatible with GJS and GNOME Shell to import modules from the npm
registry ?
On the other hand, I don't want to use code that is just open and not
free (I recently read an article that deals with npm registry issue ).
But mostly I thought it can not be done, and I did not want to add
complexity with (unnecessary) dependencies.
Moreover, there is no implementation for regex in
"imports.gi.GLib.Regex" ? Can not I use this?

Tony Houghton,
The site is written in HTML only, so I guess the Glib XML parser will
not work. Right?
Also, I don't find the documentation for XML parser in GJS, so I haven't
 managed to find how to write it in my code.

Emmanuele Bassi,
I know this "rule", but what else can I do?
Finally, as a last resort, I managed to implement it with the poor
implementation of regular expressions.

Thank you all!
Kind regards,
