How to delete a particular XML child node based on their value - php

Question

I have an XML structure like this:
<document>
<sliderimage>
<images>click.bmp</images>
<images>error_inotherpluginupload.JPG</images>
<images>dddd.jpg</images>
<images>Sunset123.jpg</images>
<images>Water lilies.jpg</images>
</sliderimage>
</document>
And I'm showing these images like this:
Code for fetching images you can see here :
<?php
$usernmeforxml = $_SESSION['username'];
$xmlpath = SITE_URL . "xml/" . $usernmeforxml . "/test.xml";
$xml = simplexml_load_string(file_get_contents($xmlpath));
$sliderimagesinner = $xml->sliderimage->images;
$imagenum = count($sliderimagesinner);
?>
</br>
<?php
for ($i = 0; $i < $imagenum; $i++)
{
?>
<a class="thumbnail" href="#thumb">
<img src="../slider_images/<?php
echo $sliderimagesinner[$i];
?>" width="120" height="70" />
<span>
<img src="../slider_images/<?php
echo $sliderimagesinner[$i];
?>" width="500" height="350" />
</span>
</a>
<?php
}
?>
Now i want to delete the image by adding a "delete" button on my images. When clicked, that image node should be deleted from the above XML file.
All things are dynamic, so it would be very helpful if anyone can help me regarding this.

Answer 1

$usernmeforxml=$_SESSION['username'];
$xmlpath=SITE_URL."xml/".$usernmeforxml."/test.xml";
$xml = simplexml_load_file($xmlpath);
if($_GET['remove'] == 'true') {
$myValue = $_GET['file'];
$xel_array = $xml->xpath("//images[text()='" . $myValue . "']");
//edited - forgot to double [0]
unset($xel_array[0][0]);
file_put_contents($xmlpath, $xml->asXML());
}
and a link like
remove
should do the trick.
