php get xml inner tag content

Solution:

XPath: http://php.net/manual/en/simplexmlelement.xpath.php

Not mandatory, you can just get all the children and loop through them, but XPath is more versatile in real world scenarios ( where you have multiple levels of XML nodes ) and is considerably more readable.

<?php
$xmlStr = <<<END
<example>
 <item productid = "1" productname = "xxx" cost = "5.3"/>
 <item productid = "2" productname = "yyy" cost = "4.0"/>
 <item productid = "3" productname = "zzz" cost = "1.75"/>
</example>
END;
$xml = new SimpleXMLElement($xmlStr); 

$items = $xml->xpath("//example/item");

$out = array();
foreach($items as $x) {
    $out [] = $x->attributes();
}

Solution:

Or you could use DOMElement

$doc = new DOMDocument();
$doc->load('domexample.xml');
$elements = $doc->getElementsByTagName('item');

$x = 0;
foreach($elements as $element)
{
    $results[$x]['productid'] = $element->getAttribute('productid');
    $results[$x]['productname'] = $element->getAttribute('productname');
    $results[$x]['cost'] = $element->getAttribute('cost');
    $x++;
}
Copy code

Solution:

<?php

$file = "filename.xml"; 
$example = simplexml_load_file($file) or die("Error: Can't Open File");

$prodidz = array();
$prodnamez = array();
$costz = array();

foreach ($example->children() as $item)
{
 $prodidz[] = $item->attributes()->productid;
 $prodnamez[] = $item->attributes()->productname;
 $costz[] = $item->attributes()->cost;
}

?>
