    <p>this is an extension to my previous post today which can be found here: <a href="https://stackoverflow.com/questions/11099208/xpath-attribute-value-check-with-a-variable-passed-using-php">Click Here</a></p> <p>Now I want to access another attribute based upon the id attribute and change that as well. Here is my modified xml file:</p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1"?&gt; &lt;document&gt; &lt;item id="a12sd"&gt; &lt;name&gt;James&lt;/name&gt; &lt;age years="25"/&gt; &lt;pdf&gt;0023.pdf&lt;/pdf&gt; &lt;/item&gt; &lt;item id="rdf23"&gt; &lt;name&gt;Alex&lt;/name&gt; &lt;age years="35"/&gt; &lt;pdf&gt;0178.pdf&lt;/pdf&gt; &lt;/item&gt; &lt;item id="2we34"&gt; &lt;name&gt;Tom&lt;/name&gt; &lt;age years="25"/&gt; &lt;pdf&gt;0886.pdf&lt;/pdf&gt; &lt;/item&gt; &lt;item id="123de"&gt; &lt;name&gt;Robby&lt;/name&gt; &lt;age years="28"/&gt; &lt;pdf&gt;1239.pdf&lt;/pdf&gt; &lt;/item&gt; &lt;/document&gt; </code></pre> <p>I have been able to update the tags using this code:</p> <pre><code>$id = "a12sd"; $xml = simplexml_load_file('items.xml'); $itemsList = $xml-&gt;xpath('/document/item[@id = "a12sd"]'); $itemsList[0]-&gt;name = "Arnold"; $xml-&gt;asXml("items.xml"); </code></pre> <p>Now I need to access the attribute age for the id="a12sd" and update the age to say: 26</p> <p>Any idea how I can reach that attribute for given id and change that value.</p> <p>Note: before changing the value the user knows only the "id" value, so based upon id value I want to change years attribute for that particular id.</p> <p>Thanks</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
