Download website links having specific elements around

I need to mirror recursively some site wallpaper images having a specific markup around, like:

<div class="wb_more">
Original Resolution: <a href="//site.com/download/space_planet_sky_94434/4800x2700">4800x2700</a><br>
Views: <a href="/download/last">96661</a>
</div>

but not others, like:

<div class="wd_resolution">
<span class="wd_res_cat">Fullscreen</span>
<span class="wd_res_cat_raz"><a class="wb_res_select" href="//site.com/download/space_planet_sky_94434/1600x1200">1600x1200</a>
...
</span>
...
</span>
</div>

Note, the URLs are the same, except for the resolutions, but the resolutions of the originals might vary, so only the markup around makes the difference, like preceeding the link with a text like Original Resolution:.

Is there a solution for this using wget or httrack or some other tool?

Thank you.

You can do this with scraping tools like scrapy. You can parse html response with css, xpath, regex or others to get links matching yours rule.

I think it is preferable to make scraper per site. For example, for the first one:

import scrapy

class imageLink(scrapy.Spider):
    name = 'imageLink'
    
    # Here the list of url to start scraping
    start_urls = ['https://images.com']

    def parse(self, response):
        # Get the link
        link = response.css('div.wb_more > a ').xpath('@href')
        # Make a callback to save the image
        yield scrapy.Request(url=url, callback=self.save_image)
   
    def save_image(self, response):
        link = response.url
        # Guess the filename from the link
        # space_planet_sky_94434
        filename = link.split('/')[5]
        # Save the image
        with open(filename, 'wb') as f:
            f.write(response.body)

If the site has pagination for images you can add a callback to parse with the link of the next page.

I didn't test the code.

You can try to use a normal wget and use regex on it (with sed or perl for example) And then download the link you obtain (wget can do it)

A basic script will look like that

wget [URL] -o MyPage.html
./GetTheFlag.pl -html MyPage.html > WallPaperList.txt
wget -i WallPaperList.txt #here you can put your image where you want

With the GetFlag.pl looks like 

use warnings; 
use strict; 
use Getopt::Long;
my $Url;
my $MyPage;
GetOptions("html=s" => \$MyPage);
open(FILE,$MyPage);
my $content=FILE;
my @urls=($content =~ //gi) #insert here a regex depending on the flags around
foreach my $i (@urls) {
    print "$i\n";
}

For example if your url are <a href="url">New Wallpaper</a> the regex will be 

 =~ /<a href="(\w+)">New Wallpaper</a>

care about \w it misses some character that can't be used in var name as -

Hope this is clear enough.
