Question

I have the file.xml contains:

<?xml version="1.0"?>
<Document xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:iso:std:iso:20022:tech:xsd:test.001.001.01">
  <book>
  <author>Jack Herrington</author>
  <title>PHP Hacks</title>
  <publisher>O'Reilly</publisher>
  </book>
</Document>

anybody know How Can I get this information in the <document....> example the xmlns?

<Document xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:iso:std:iso:20022:tech:xsd:test.001.001.01">

Answer 1

Use SimpleXML to get namespaces like so:

$xmlstr = <<<XML
<?xml version="1.0"?>
<Document xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:iso:std:iso:20022:tech:xsd:test.001.001.01">
  <book>
  <author>Jack Herrington</author>
  <title>PHP Hacks</title>
  <publisher>O'Reilly</publisher>
  </book>
</Document>
XML;

$xml = simplexml_load_string($xmlstr);
$namespaces =  $xml->getDocNamespaces(); 
var_export($namespaces);

this code will produce:

array ( 'xsd' => 'http://www.w3.org/2001/XMLSchema', 'xsi' => 'http://www.w3.org/2001/XMLSchema-instance', '' => 'urn:iso:std:iso:20022:tech:xsd:test.001.001.01', )

The array of all namespaces declared in the document.
