It runs an XPath query on XML data
Example
<?php
$xml = simplexml_load_file(“test.xml”);
$xml->registerXPathNamespace(“msg”,”http://www.phpcodez.com”);
$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”);
$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/”>
<server ver=”5″>Apache</server>
<lan>PHP</lan>
<client>Javascript</client>
</web>
It returns the name of a SimpleXML element
