How to access <tag> by its id attribute and not array position?

Question

I would like to understand how to access a <tag> by its id and not through array position. Example:

<someNameHere id="hello">
 <home>
 </home>
 <home>
 </home>
</someNameHere>
<someNameHere id="hi">
 <home>
 </home>
 <home>
 </home>
</someNameHere>

I don't want to do this:

$myXML->someNameHere[1]->home[0]

I want to go access someNameHere by its ID "hi".

Answer 1

You'll have to use XPath for that.

$nodes = $myXML->xpath('//*[@id="hi"]');

if (!empty($nodes))
{
    $someNameHere = $nodes[0];
}
