How to integrate a link to parse in PHP Simple XML - php

Question

I need to download all photos about estates from an XML to save on the server. Every estate child in the XMl has a general section with all information and then a node called Foto (estate's photos) and another one for plans (Planimetria). The link of every image is structured as is:
<Link>http://www.site.it/ImageView.ashx?id=[photoID]&reduce=1438[can be set as I want es: 1000, 960, 1080]</Link>
I need to call it inside the $url_photo and $url_plan so I can read the photoID from XML and set resolution (1438,1000,960) with a global variable.
This is my code:
<?php
$xml = simplexml_load_file("Schede.xml"); // your xml
$path = '/mnt/c/Users/Giuseppe/Desktop/FotoTest/';
$i = 1;
$resolution = '1000';
// Estate Image
foreach($xml->CR03_SCHEDE as $estate){
//if((string) $estate['ELIMINATO'] = "NO"){
echo "\nEstate n $i Images\n";
foreach($estate->Foto->CR04_SCHEDE_FOTO as $photo){
$url_photo = (string) $photo->Link;
$filename_photo = basename($photo->CR04_FILENAME); // get the filename
if(file_exists($path . $filename_photo)) {
echo "file $filename_photo already exists \n";
}
else {
$img_photo = file_get_contents($url_photo); // get the image from the url
file_put_contents($path . $filename_photo, $img_photo); // create a file and feed the image
echo "file $filename_photo created \n";
}
}
// Plans
echo "\nEstate n $i plans\n";
foreach($estate->Planimetria->CR04_SCHEDE_FOTO as $plan) {
$url_plan = (string) $plan->'http: // www.site.it/ImageView.ashx?id=' . $plan->ID . '&reduce=' . $resolution; //$plan->Link;
$filename_plan = basename($plan->CR04_FILENAME);
if(file_exists($path . $filename_plan)) {
echo "file planimetry $filename_plan already exists \n";
}
else {
$img_plan = file_get_contents($url_plan); // get the image from the url
file_put_contents($path . $filename_plan, $img_plan); // create a file and feed the image
echo "file planimetry $filename_plan created \n";
}
}
$i++;
/*}
else{
echo "$estate->attributes(Riferimento)"."Deleted\n";
}*/
}
?>
I also have a problem with the first if commented:
if((string) $estate['ELIMINATO'] = "NO")...
Eliminato is an attribute of CR03_SCHEDE but the script won't read it and in any case go inside the if.
The complete XML has about 70/80 properties and the foreach works well to download all images, but I need that it should download the only one that has that attribute equals to NO
This is the example of XML (only one estate): link
Thanks to all

This is a classic mistake:
if((string) $estate['ELIMINATO'] = "NO")
You used the assignment operator instead of the comparison operator. Please use this exact form:
if ('NO' == (string)$estate['ELIMINATO'])
