How to parse an HTML table with rowspans in Python?
<p><strong>The problem</strong></p>

<p>I'm trying to parse an HTML table with rowspans in it, as in, I'm trying to parse my college schedule.</p>

<p>I'm running into the problem where if the last row contains a rowspan, the next row is missing a TD where the rowspan is now that TD that is missing.</p>

<p>I have no clue how to account for this and I hope to be able to parse this schedule.</p>

<p><strong>What I tried</strong></p>

<p>Pretty much everything I can think of.</p>

<p><strong>The result I get</strong>
</p>

<pre><code>[
    {
        'blok_eind': 4,
        'blok_start': 3,
        'dag': 4, # Should be 5
        'leraar': 'DOODF000',
        'lokaal': 'ALK C212',
        'vak': 'PROJ-T',
    },
]
</code></pre>

<p>As you can see, there's a <code>vak</code> key with the value <code>PROJ-T</code> in the output snippet above, <code>dag</code> is <code>4</code> while it's supposed to be <code>5</code> (a.k.a Friday/Vrijdag), as seen here:</p>

<p><strong>The result I want</strong></p>

<p>A Python dict() that looks like the one posted above, but with the right value</p>

<p>Where:</p>

<ul>
<li><code>day</code>/<code>dag</code> is an int from 1~5 representing Monday~Friday</li>
<li><code>block_start</code>/<code>blok_start</code> is an int that represents when the course starts (Time block, left side of table)</li>
<li><code>block_end</code>/<code>blok_eind</code> is an int that represent in what block the course ends</li>
<li><code>classroom</code>/<code>lokaal</code> is the classroom's code the course is in</li>
<li><code>teacher</code>/<code>leraar</code> is the teacher's ID </li>
<li><code>course</code>/<code>vak</code> is the ID of the course</li>
</ul>
