This assumes you are using BeautifulSoup 4.7+ which has the improved select library.

I want to answer why, what you did didn't work, and then show you how to easily make it work.

The reason your code doesn't work is for a couple of reasons. When you inspect an HTML in a browser, it can sometimes show you HTML that a parser liberally modifies to meet what it thinks your intentions are, and to give you more proper HTML. For instance, when you request the raw HTML, there are no <code>tbody</code> tags, but in a browser, it automatically inserts it as it is more proper.

<code>html.parser</code> does not insert <code>tbody</code> if not found in the raw HTML. If you wanted to see that done in BeautifulSoup, you'd need to install <code>html5lib</code> and use that parser <code>soup = BeautifulSoup (source.text, 'html5lib')</code>.

Sometimes when I run into an unexpected parser problem, I'll print out the soup object's content to a separate file so that I can analyze what is different from what I expected when I looked at it in a browser.

<hr>

So, assuming we are still using <code>html.parser</code>, let's simplify our select and also not look for <code>tbody</code>.

<pre><code>from bs4 import BeautifulSoup
import requests

source = requests.get('https://www.expireddomains.co.nz/search.php?action=search&amp;status=6&amp;results_per_page=100&amp;page=2')
soup = BeautifulSoup (source.text, 'html.parser')
elems = soup.select('table.DomainList &gt; tr:nth-child(2) &gt; td:nth-child(2) &gt; a')
print(elems)
</code></pre>

Output

<pre><code>[&lt;a href="/register.php?domain_id=2196993"&gt;absca.co.nz&lt;/a&gt;] 
</code></pre>

New-ish to Python, but still self-learning online etc. 

I'm trying to build a webscraper with beautifulsoup and so far into it I have found what elements on the page I want to scrape and print, but upon testing the first one it just prints empty brackets instead of the html/text on the site that I need. 

Here is the code so far: 

<pre><code>from bs4 import BeautifulSoup
import requests

source = requests.get('https://www.expireddomains.co.nz/search.php?action=search&amp;status=6&amp;results_per_page=100&amp;page=2')
soup = BeautifulSoup (source.text, 'html.parser')
elems = soup.select('body &gt; table &gt; tbody &gt; tr &gt; td:nth-child(3) &gt; div.PageTabsBox &gt; form:nth-child(4) &gt; table.DomainList &gt; tbody &gt; tr:nth-child(2) &gt; td:nth-child(2) &gt; a')
print(elems)
</code></pre>

Any help would be appreciated.
