It runs an XPath query on XML data

Example

<?php
$xml = simplexml_load_file(“test.xml”);
$xml->registerXPathNamespace(“msg”,”http://www.phpcodez.com&#8221;);
$result = $xml->xpath(“msg:web”);
?>

XML

<?xml version=”1.0″ encoding=”ISO-8859-1″?>
<web>
<server ver=”5″>Apache</server>
<lan>PHP</lan>
<client>Javascript</client>
</web>

It returns  SimpleXMLElement object from an XML string

Example

<?php
$xmlstring = ‘<?xml version=”1.0″ encoding=”ISO-8859-1″?><lan>PHP</lan>’;
$xml = simplexml_load_string($xmlstring);
print_r($xml);
?>

Output

SimpleXMLElement Object ( [0] => PHP )

It returns  SimpleXMLElement object from an XML document

Example

<?php
$xml = simplexml_load_file(‘test.xml’);
?>

It returns SimpleXMLElement object from a DOM node

Example

<?php
$dom = new domDocument;
$dom->loadXML(‘<web><server>Apache</server></web>’);
$xml = simplexml_import_dom($dom);
echo $xml->server;
?>

Output

Apache

It creates a namespace context for the next XPath query

Example

<?php
$xml = simplexml_load_file(“test.xml”);
$xml->registerXPathNamespace(“msg”,”http://www.phpcodez.com&#8221;);
$result = $xml->xpath(“msg:web”);
?>

XML

<?xml version=”1.0″ encoding=”ISO-8859-1″?>
<web>
<server ver=”5″>Apache</server>
<lan>PHP</lan>
<client>Javascript</client>
</web>

It returns the namespaces from XML data

Example

<?php
$xml = simplexml_load_file(‘test.xml’);
echo “<pre>”;

print_r($xml->getNamespace());

?>

Output

Array
(
[b] => http://www.phpcodez.come/
)

XML

<?xml version=”1.0″ encoding=”ISO-8859-1″?>
<web xmlns:b=”http://www.phpcodez.com/”&gt;
<server ver=”5″>Apache</server>
<lan>PHP</lan>
<client>Javascript</client>
