XML PHP Get children value - php

Question

XML:
<Result xmlns="" xmlns:xsi="" totalResultsAvailable="0" totalResultsReturned="0" schk="true" totalLooseOffers="0" xsi:schemaLocation="">
<details>
<ID></ID>
<applicationVersion>1.0</applicationVersion>
<applicationPath/>
<date>2016-05-23T12:17:16.369-03:00</date>
<elapsedTime>17</elapsedTime>
<status>success</status>
<message>success</message>
</details>
<category id="1">
<thumbnail url="http://image.google.com/test.jpg"/>
<links>
<link url="www.google.com" type="category"/>
<link url="www.google2.com" type="xml"/>
</links>
<name>Category</name>
<filters>
<filter id="1" name="Filter1">
<value id="1" value="Test1"/>
<value id="2" value="Test2"/>
<value id="3" value="Test3"/>
</filter>
<filter id="2" name="Filter2">
<value id="1" value="Test4"/>
<value id="2" value="Test5"/>
<value id="3" value="Test6"/>
</filter>
</filters>
</category>
</Result>
PHP:
$xml = simplexml_load_file("http://xml.com");
foreach($xml->category->filters as $filters){
foreach($filters->children() as $child){
echo $child['value'];
}
}
I'm trying to get the filters value, but nothing shows with the code i have. I saw something about xpath but don't know if it's applicable in this situation. Do you have any clue?

When the XML looks like this:
<Result xmlns="" xmlns:xsi="" totalResultsAvailable="0" totalResultsReturned="0" schk="true" totalLooseOffers="0" xsi:schemaLocation="">
<details>
<ID></ID>
<applicationVersion>1.0</applicationVersion>
<applicationPath/>
<date>2016-05-23T12:17:16.369-03:00</date>
<elapsedTime>17</elapsedTime>
<status>success</status>
<message>success</message>
</details>
<subCategory id="1">
<thumbnail url="http://image.google.com/test.jpg"/>
<name>Subcategory</name>
</subCategory>
<subCategory id="2">
<thumbnail url="http://image.google.com/test2.jpg"/>
<name>Subcategory2</name>
</subCategory>
</Result>
Then am able to do this:
foreach($xml->subCategory as $subCategory){
$categoryId = $subCategory['id'];
$categoryName = $subCategory->name;
}

The elements you reference as $child in the inner loop actually point to the <filter> nodes, not the children <value> nodes you are attempting to target attributes for. So this really is just a matter of extending the outer foreach loop to iterate over $xml->category->filters->filter rather than its parent $xml->category->filters.
// Iterate the correct <filter> node, not its parent <filters>
foreach ($xml->category->filters->filter as $filter) {
foreach($filter->children() as $child){
echo $child['value'] . "\n";
}
}
Here it is in demonstration: https://3v4l.org/Rqc4Y
Using xpath, you can target the inner nodes directly.
$values = $xml->xpath('//category/filters/filter/value');
foreach ($values as $value) {
echo $value['value'];
}

Both of these examples output
Test1
Test2
Test3
Test4
Test5
Test6
