Getting schemaLocation value from XML file (using DomDocument or SimpleXML?)

[xandrani]

Is it possible to extract the schemaLocation from an XML file using an appropriate call?

 

I know I can easily use a regex but if there was an official way to get the schemaLocation then I'd prefer it.

 

 

Example snippet of XML file:

 

<?xml version="1.0" encoding='UTF-8'?>
<books
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="file:///documents%20and%20settings/Fred/Desktop/example.xsd">
<book> ...

 

A function such as:

get_schema_location(&$schema_location)

 

would return by reference the string:

"file:///documents%20and%20settings/Fred/Desktop/example.xsd"

 

Any ideas?

DOM (where $doc is a DOMDocument)

 

$doc->documentElement->getAttributeNS($dom->lookupNamespaceURI('xsi'), 'schemaLocation');

 

SimpleXML (where $doc is a SimpleXMLElement)

 

echo $doc->attributes('xsi', TRUE)->schemaLocation;
