    <pre><code>Quite simply can you do a conditional scrape, i.e. I want an &lt;a&gt; tag within a parent, and if a &lt;span&gt; is contained within that parent (so the span is holding the &lt;a&gt;, instead of the parent), I still want to drill into the span regardless for the &lt;a&gt; </code></pre> <hr> <p>Hopefully this example will provide enough details.</p> <pre><code>&lt;tr&gt; &lt;td&gt;1989&lt;/td&gt; &lt;td&gt; &lt;i&gt; &lt;a href="/wiki/Always_(1989_film)" title="Always (1989 film)"&gt;Always&lt;/a&gt; &lt;/i&gt; &lt;/td&gt; &lt;td&gt;Pete Sandich&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>I can access the <code>&lt;a&gt;</code> fine using:</p> <p><code>all_links = doca.search('//tr//td//i//a[@href]')</code></p> <p>But what I want to know is can I also add a conditional, so if there is a span surrounding the <code>&lt;a&gt;</code>, can this be put in the search?</p> <pre><code> &lt;tr&gt; &lt;td&gt;1989&lt;/td&gt; &lt;td&gt; &lt;i&gt; &lt;span&gt; &lt;a href="/wiki/Always_(1989_film)" title="Always (1989 film)"&gt;Always&lt;/a&gt; &lt;/span&gt; &lt;/i&gt; &lt;/td&gt; &lt;td&gt;Pete Sandich&lt;/td&gt; &lt;/tr&gt; </code></pre> <p>So is there a way to conditionally grab the <code>&lt;a&gt;</code>, something like so:</p> <p><code>all_links = doca.search('//tr//td//i//?span//a[@href]')</code></p> <p>Where ?span would be a conditional - i.e. if a span is there, then enter that level, and then enter the link.</p> <p>And if no span is there then skip it and just enter the link.</p> <p>Thanks in advance, greatly appreciate any help!</p> <p>Shane</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
