Get values XML feed by name - PHP - php

Question

I'm using XML to insert products into my db with PHP. I can access / read the xml feed with the following code:
$xml=simplexml_load_file('testfeed.xml') or die("Error: Cannot create object");
foreach($xml->children() as $product) {
$pname = $product->name;
$pdescr = $product->description;
echo $pname;
echo $pdescr;
}
Below is my example XML:
<product ID="9">
<name>Product X</name>
<properties>
<property name="categoryPath">
<value>path-to-category</value>
</property>
<property name="stock">
<value>1</value>
</property>
</properties>
</product>
It's easy to get the values for name, but how do I get the value of the categorypath, since this one is inside properties->property->value and declared in the <property name="categoryPath">?
Thanks!

Answer 1

The easiest way without looping too much through the structures will be using XPath:
$values = $xml->xpath('//property[#name="categoryPath"]/value');
Just loop through the returned array and cast each result to string when needed, and you're done.

Answer 2

$xml=simplexml_load_file('./testfeed.xml') or die("Error: Cannot create object");
foreach($xml->children() as $product) {
$pname = $product->name;
$pdescr = $product->properties->property["name"];
$pdvalue = (string)$product->properties->property->value;
echo "Prdo Name: $pname\n";
echo "Prod Desc: $pdescr\n";
echo "Prod Value: $pdvalue\n";
}
Output:
Prdo Name: Product X
Prod Desc: categoryPath
Prod Value: path-to-category

Update:
While Jossif's answer is very good at getting all the nodes in bulk I'm including an edit for updated xml structure without using xpath:
$property = $product->properties->property;
$propertyAttribute = $property->attributes()->{'name'};
$catPath = ($propertyAttribute=="categoryPath")? $property->value : "value for missing paths";
print $catPath . PHP_EOL;
Since you don't seem to have any other similar xml nodes, you don't need the attribute to separate them.
You should be able to safely use this
$catPath = $product->properties->property->value;
print $catPath;
to get the string from the value node.
