$string = <<<XML
<?xml version='1.0'?>
<document>
<books>
<book>
<qty>12</qty>
<title>C++</title>
</book>
<book>
<qty>21</qty>
<title>PHP</title>
</book>
</books>
<books>
<book>
<qty>21</qty>
<title>PHP</title>
</book>
</books>
</document>
XML;
$newsXML = new SimpleXMLElement($string);
$xml = simplexml_load_string($string);
print_r($xml);
$A = SimpleXMLElement Object
(
[books] => Array
(
[0] => SimpleXMLElement Object
(
[book] => Array
(
[0] => SimpleXMLElement Object
(
[qty] => 12
[title] => C++
)
[1] => SimpleXMLElement Object
(
[qty] => 21
[title] => PHP
)
)
)
[1] => SimpleXMLElement Object
(
[book] => SimpleXMLElement Object
(
[qty] => 21
[title] => PHP
)
)
)
)
AND Have an $arr use to indicate that which elements of $A will delete .
$arr = array(
0=> array(0=>'12;C++'),
1=> array(0=>'21;PHP')
);
So $A will be return the remain elements :
$A = SimpleXMLElement Object
(
[books] => Array
(
[0] => SimpleXMLElement Object
(
[book] => Array
(
[0] => SimpleXMLElement Object
(
[qty] => 21
[title] => PHP
)
)
)
)
)
and it equivalence to $xml will like this:
<?xml version='1.0'?>
<document>
<books>
<book>
<qty>21</qty>
<title>PHP</title>
</book>
</books>
</document>
