Use PHPs DOMDocument:

<?php 
$xml = new DOMDocument();
$xml->loadXML("your/xml/file.xml");
$nodes = $xml->getElementsByTagName($_GET['xml']);
foreach($nodes as $node)
{
    echo $node->textContents . "<br><br>";
}
?>

error

 

Warning: DOMDocument::loadXML() [domdocument.loadxml]: Start tag expected, '<' not found in Entity, line: 1 in C:\Apache-htdocs\example1.php on line 3

Actually you need to insert xml string for the loadxml function so do something like loadxml(file_get_contents("your/xml/file.xml"))

[simzam]

when i remove this tag <?xml version="1.0" encoding="ISO-8859-1"?> it loads XML but not showing any results

 

 

http://myurl.com/index.php?$xml=link1

when i try to access via URL nothing happens not getting any results from my XML as mention in first post

Your link is wrong: http://myurl.com/index.php?$xml=link1

 

It should just be: http://myurl.com/index.php?xml=link1  No dollar sign!

[simzam]

http://myurl.com/index.php?xml=link1

still it loads blank page

 

my XML:

<note>
<link1>www.2advanced.com</link1>
<link2>www.hotmail.com</link2>
<link3>www.gmail.com</link3>
<link4>www.twitter.com</link4>
</note> 

 

my php :

<?php 
$xml = new DOMDocument();
$xml->loadXML(file_get_contents('link.xml'));
$nodes = $xml->getElementsByTagName($_GET['xml']);
foreach($nodes as $node)
{
    echo $node->textContents . "<br><br>";
}
?>

There are three problems, one is stopping your script from being useful and another is just a choice. The third is a general tip.

 

Firstly, the correct property to use is $node->textContent. Next, you can (and probably should) use $xml->load("link.xml"); and finally please learn to enable, display and understand error messages: use error_reporting(-1) while you're writing code and take note of the helpful messages.

problem solved !

 

Thanks a lot  johnny86  and salathe for your time 

 

third tip appreciated  !

As every things working absolute fine

I'm using  error_reporting(-1) above my PHP code and  getting this error  how to get rid of it

 

Notice: Undefined index: xml in C:\Apache-htdocs\example1.php on line 5

make sure $_GET['xml'] is set or isn't empty before using it's value

 

if (!empty($_GET['xml'])) {
     $xml = new DOMDocument();
     $xml->loadXML(file_get_contents('link.xml'));
     $nodes = $xml->getElementsByTagName($_GET['xml']);
     foreach($nodes as $node) {
          echo $node->textContents . "<br><br>";
     }
}
