It allows to define a content that is displayed between every two iterations of the loop. It takes no attributes:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:repeat</span> <span style="color: #000066;">times</span>=<span style="color: #ff0000;">&quot;5&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:separator<span style="color: #000000; font-weight: bold;">&gt;</span></span></span> / <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:separator<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    {$opt.repeat}
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:repeat<span style="color: #000000; font-weight: bold;">&gt;</span></span></span></pre>

<p>The code above produces the following result:</p>

<pre><code>1 / 2 / 3 / 4 / 5
</code></pre>

<p>As we can see, the separator content apears neither before the first element nor after the last one.</p>

<h2>Attribute version</h2>

<p>The separators can be defined with an extra loop instruction attribute, <code>separator</code> that takes any expression as its value. By switching to the <code>str</code> namespace, we may define a static separator, or stay in the default one to read it from variable:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:repeat</span> <span style="color: #000066;">times</span>=<span style="color: #ff0000;">&quot;5&quot;</span> <span style="color: #000066;">str:separator</span>=<span style="color: #ff0000;">&quot; / &quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
    {$opt.repeat}
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:repeat<span style="color: #000000; font-weight: bold;">&gt;</span></span></span></pre>

<p>This code will produce the same code, as the first example. Below, we can see, how to load the separator from a variable:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:repeat</span> <span style="color: #000066;">times</span>=<span style="color: #ff0000;">&quot;5&quot;</span> <span style="color: #000066;">separator</span>=<span style="color: #ff0000;">&quot;$separatorDef&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
    {$opt.repeat}
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:repeat<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
&nbsp;
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:repeat</span> <span style="color: #000066;">times</span>=<span style="color: #ff0000;">&quot;5&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:separator<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>{$separatorDef}<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:separator<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    {$opt.repeat}
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:repeat<span style="color: #000000; font-weight: bold;">&gt;</span></span></span></pre>

<p>Note that the <code>opt:separator</code> tag allows to create more sophisticated separators constructed from other instructions. In the last example, we see a dynamic separator that grows during the execution:</p>

<pre class="xml"><span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:repeat</span> <span style="color: #000066;">times</span>=<span style="color: #ff0000;">&quot;5&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>
    <span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;opt:separator<span style="color: #000000; font-weight: bold;">&gt;</span></span><span style="color: #000000; font-weight: bold;">&lt;opt:repeat</span> <span style="color: #000066;">times</span>=<span style="color: #ff0000;">&quot;$opt.repeat&quot;</span><span style="color: #000000; font-weight: bold;">&gt;</span></span>-<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:repeat<span style="color: #000000; font-weight: bold;">&gt;</span></span><span style="color: #000000; font-weight: bold;">&lt;/opt:separator<span style="color: #000000; font-weight: bold;">&gt;</span></span></span>
    {$opt.repeat}
<span style="color: #009900;"><span style="color: #000000; font-weight: bold;">&lt;/opt:repeat<span style="color: #000000; font-weight: bold;">&gt;</span></span></span></pre>

<p>The result:</p>

<pre><code>1-2--3---4----5
</code></pre>
