<h2><a href="#terminology" name="terminology"></a>Terminology</h2>
|
||
<p>In this documentation the following terminology is used:</p>
|
||
<ul>
|
||
<li><strong>dispatcher</strong>: a <code>dispatcher</code> is a function (or more probably a map) which takes one argument, the tag of the element as a keyword, and returns a <code>processor</code>, q.v.</li>
|
||
<li><strong>processor</strong>: a <code>processor</code> is a function of two arguments, an <a href="https://github.com/cgrand/enlive">Enlive</a> encoded (X)HTML element and a <code>dispatcher</code> as described above, which processes elements into the desired format.</li>
|
||
</ul>
|
||
<h2><a href="#generality" name="generality"></a>Generality</h2>
|
||
<p><strong>NOTE</strong> that while <code>processors</code> within the <code>html-to-md</code> package generally process elements into strings (since Markdown is a text format), when processing into an XML format it will generally be preferable that <code>processors</code> should return Enlive style elements.</p></div></div><div class="public anchor" id="var-process"><h3>process</h3><div class="usage"><code>(process element dispatcher)</code></div><div class="doc"><div class="markdown"><p>Process this <code>element</code>, assumed to be a [HT|SG|X]ML element in <a href="https://github.com/cgrand/enlive">Enlive</a> encoding, using this <code>dispatcher</code>,</p>
|
||
<p>Such a function should take two arguments, the <code>element</code> itself and a dispatcher which will normally (but not necessarily) be the <code>dispatcher</code> supplied to this function.</p>
|
||
<p>If the dispatcher returns <code>nil</code>, the default behaviour is that <code>process</code> is mapped over the content of the element.</p>
|
||
<p>If <code>element</code> is not an [HT|SG|X]ML element in Enlive encoding as descibed above, then</p>
|
||
<ol>
|
||
<li>if the <code>element</code> is a string, returns that string unaltered;</li>
|
||
<li>if the <code>element</code> is a sequence or vector, maps <code>process</code> across the members of the sequence;</li>
|
||
<li>otherwise, returns <code>nil</code>.</li>
|
