DOMXPATH Evaluate string with variable nested position - php

Question

I've been using DOMXPATH and I love it, but I need it to be a little more intuitive.
Some clients add some extra HTML in their code, which screws up our project.
Example 1:
<div id="Fooen">
<span class="FooTitle">Overdracht</span>
<span class="Foo koopprijs">
<span class="FooName">Vraagprijs</span>
<span class="FooValue">€ 299.000,-</span>
</span>
<span class="Foo aanvaarding">
<span class="FooName">Aanvaarding</span>
<span class="FooValue">In overleg</span>
</span>
</div>
We can get the SPAN name and values fine with this:
$filtered = $domxpath->query("//div[#class='Fooen']/span");
foreach ($filtered as $myItem) {
$temp_name = $domxpath->evaluate("string(descendant::span[#class='FooName'])", $myItem);
$name = strtolower(preg_replace('/\s*/', '', $temp_name));
$value = $domxpath->evaluate("string(descendant::span[#class='FooValue'])", $myItem);
}
But, sometimes the client added code, so the nodes are now deeper. I cannot seem to find an answer to this without mapping it all the way down.
Example 2:
<div id="Fooen">
<div>
<div class="blok-sizer"></div>
<div id="" class="block">
<div class="top">
<div class="center column"></div>
</div>
<div class="middle">
<div class="center column">
<span class="FooTitle">Overdracht</span>
<span class="Foo first transactiestatus">
<span class="FooName">Status</span>
<span class="FooValue">Beschikbaar</span>
</span>
<span class="Foo koopprijs">
<span class="FooName">Vraagprijs</span>
<span class="FooValue">€ 975.000,-</span>
</span>
</div>
</div>
</div>
</div>
</div>
But now, this won't work:
$filtered = $domxpath->query("//div[#class='Fooen']/span");
foreach ($filtered as $myItem) {
$temp_name = $domxpath->evaluate("string(descendant::span[#class='FooName'])", $myItem);
$name = strtolower(preg_replace('/\s*/', '', $temp_name));
$value = $domxpath->evaluate("string(descendant::span[#class='FooValue'])", $myItem);
}
I have tried variations like these:
$domxpath->evaluate("string(descendant::*[#class='FooName'])", $myItem);
$domxpath->evaluate("string(//*[#class='FooName'])", $myItem);
$domxpath->evaluate("string(*[#class='FooName'])", $myItem);
$domxpath->evaluate("string(.//span[#class='FooName'])", $myItem);
Is there a way to get the outcome of a string, even if it is not at the same place each time, thus more flexible?
Edit, here is a ready to copy/paste sample I am currently working with. First is the working one, second is the one I'd like to get working from root to end and not fixed but flexible. If I knew how to fiddle, I would, sorry.
<?php
function getDom($url = "")
{
$str = $url;
$internalErrors = libxml_use_internal_errors(true);
$dom = new \DOMDocument('1.0', 'UTF-8');
$dom->loadHTML($str);
libxml_use_internal_errors($internalErrors);
return $dom;
}
$domcode = '<div class="Fooen">
<span class="FooTitle">Overdracht</span>
<span class="Foo koopprijs">
<span class="FooName">Vraagprijs</span>
<span class="FooValue">€ 299.000,-</span>
</span>
<span class="Foo aanvaarding">
<span class="FooName">Aanvaarding</span>
<span class="FooValue">In overleg</span>
</span>
</div>';
$dom = getDom($domcode);
$html = '';
$domxpath = new \DOMXPath($dom);
$newDom = new \DOMDocument;
$newDom->formatOutput = true;
$filtered = $domxpath->query("//div[#class='Fooen']/span");
foreach ($filtered as $myItem) {
$temp_name = $domxpath->evaluate("string(descendant::span[#class='FooName'])", $myItem);
echo strtolower(preg_replace('/\s*/', '', $temp_name));
echo " = ";
echo $domxpath->evaluate("string(descendant::span[#class='FooValue'])", $myItem);
echo "<br>";
}
echo "<br>";
$domcode = '

<span class="FooValue">€ 975.000,-</span>
</span>
</div>
</div>
</div>
</div>
</div>';
$dom = getDom($domcode);
$html = '';
$domxpath = new \DOMXPath($dom);
$newDom = new \DOMDocument;
$newDom->formatOutput = true;
$filtered = $domxpath->query("//div[#class='center column']/span");
foreach ($filtered as $myItem) {
$temp_name = $domxpath->evaluate("string(descendant::span[#class='FooName'])", $myItem);
echo "<br>";
echo strtolower(preg_replace('/\s*/', '', $temp_name));
echo " = ";
echo $domxpath->evaluate("string(descendant::span[#class='FooValue'])", $myItem);
}

Answer 1

Turns out I had been beating the wrong line of code all day. Apparently I needed to broaden the Filtered Search. If there's room for non-greedy code I'm all ears. Otherwise, I hope it helps somebody else.
$filtered = $domxpath->query("//div[#class='Fooen']/descendant::span");
