Better HTML parsing

[alexrs]

PROBLEM: In the current implementation the answer is obtained as text but some answers contains links in the form of:

You can find more info here

where here is an hyperlink to some other resources, but it is not shown.

POSSIBLE SOLUTION: Get the answer as HTML, parse it, and display those links properly, for example:

You can find more info here (http://...)

goquery has a utility function named OuterHtml() which gives the raw html for the selected node.

Activating this function with a query such as....

pop -l go print string

the following raw html is available.

<div class="post-text" itemprop="text">
<p><a href="http://golang.org/pkg/fmt/#Sprintf">Sprintf</a></p>

<p><a href="https://tour.golang.org/methods/19">Here also</a> is a use of it in the tutorial, &#34;A Tour of Go.&#34;</p>

<pre><code>return fmt.Sprintf(&#34;at %v, %s&#34;, e.When, e.What)
</code></pre>
</div>

Which is helpful to illustrate what you are referring to above.

I think that in terms of the hyperlinks, goquery could be utilized to grab the hyperlinks from the tags and append them as text to the inner html.

Just quickly played around with goquery and came up with something like this...

doc.Find(".answercell .post-text").First().Find("a").Each(func(i int, s *goquery.Selection) {
    href, success := s.Attr("href")
    if success == true {
        href = " (" + href + ")"
        s.AppendHtml(href)
    }
})

Seems to perform as expected. Let me know what you think.

I have merged your PR! If you have any other idea of how to improve Pop, I'll be happy to know it! I have also thought about highlighting in some way the titles (h1, h2, h3..) and some other HTML tags.
