    <p>You should be able to use <code>"//*[firstname='Sheila' and position() &lt;= 100]</code>"</p> <p><strong>Edit:</strong></p> <p>Given the following XML:</p> <pre><code>&lt;root&gt; &lt;country.php desc="country.php" language="fr|pt|en|in" editable="Yes"&gt; &lt;en/&gt; &lt;in&gt; &lt;cityList desc="cityList" language="in" editable="Yes" type="Array" index="No"&gt; &lt;element0&gt;Abu&lt;/element0&gt; &lt;element1&gt;Agartala&lt;/element1&gt; &lt;element2&gt;Agra&lt;/element2&gt; &lt;element3&gt;Ahmedabad&lt;/element3&gt; &lt;element4&gt; Ahmednagar&lt;/element4&gt; &lt;element5&gt;Aizwal&lt;/element5&gt; &lt;element150&gt;abcd&lt;/element150&gt; &lt;/cityList&gt; &lt;/in&gt; &lt;/country.php&gt; &lt;/root&gt; </code></pre> <p>You can use the following XPath to get the first three cities:</p> <pre><code>//cityList/*[position()&lt;=3] </code></pre> <p>Results:</p> <pre><code>Node element0 Abu Node element1 Agartala Node element2 Agra </code></pre> <p>If you want to limit this to nodes that start with <code>element</code>:</p> <pre><code>//cityList/*[substring(name(), 1, 7) = 'element' and position()&lt;=3] </code></pre> <p>Note that this latter example works because you're selecting <em>all</em> the child nodes of cityList, so in this case <code>Position()</code> works to limit the results as expected. If there was a mix of other node names under the cityList node, you'd get undesirable results.<br> For example, changing the XML as follows:</p> <pre><code>&lt;root&gt; &lt;country.php desc="country.php" language="fr|pt|en|in" editable="Yes"&gt; &lt;en/&gt; &lt;in&gt; &lt;cityList desc="cityList" language="in" editable="Yes" type="Array" index="No"&gt; &lt;element0&gt;Abu&lt;/element0&gt; &lt;dog&gt;Agartala&lt;/dog&gt; &lt;cat&gt;Agra&lt;/cat&gt; &lt;element3&gt;Ahmedabad&lt;/element3&gt; &lt;element4&gt; Ahmednagar&lt;/element4&gt; &lt;element5&gt;Aizwal&lt;/element5&gt; &lt;element150&gt;abcd&lt;/element150&gt; &lt;/cityList&gt; &lt;/in&gt; &lt;/country.php&gt; &lt;/root&gt; </code></pre> <p>and using the above XPath expression, we now get </p> <pre><code>Node element0 Abu </code></pre> <p>Note that we're losing the second and third results, because the <code>position()</code> function is evaluating at a higher order of precedence - the same as requesting "give me the first three nodes, now out of those give me all the nodes that start with 'element'".</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.
