get xml element using php - php

Question

I have an XML page called (www.example.com/name.xml)
it contains the bellow elements :
<xml>
<names>
<name id='6' >Name 1 </name>
<name id='7'>Name 2</name>
<name id='8'>Name 3</name>
</names>
</xml>
and here is my PHP script :
<?php
$id='6';
$url = "www.example.come/name.xml";
$xml = simplexml_load_file($url);
$position ="$xml->name id='$id' ";
?>
So how can I get it ?

Answer 1

You can simply use xpath for this:
$id='6';
$xml = simplexml_load_file($url);
$position = (string)$xml->xpath("//name[#id='$id']")[0];
echo $position;
Output:
Name 1
This uses xpath to get the text from the <name> where id is 6. Then it casts the SimpleXMLElement to (string), thus providing the output.

Answer 2

Based on your provided data, you could do it like this:
$id='6';
foreach($xml->names->name as $name) {
if ((string)$name->attributes()->id === $id) {
// here $name will be the element for which the attribute id='6'
var_dump($name);
}
}
Will result in:
object(SimpleXMLElement)#3 (2) {
["#attributes"]=>
array(1) {
["id"]=>
string(1) "6"
}
[0]=>
string(7) "Name 1 "
}
$name is of type SimpleXMLElement and the value you are looking for is in the attributes.
