Get the text content of a node, but ignore child nodes

Question

  a
   b 

both $foo->textContent and $foo->nodeValue return a

Answer 1

This might be helpful. Using what I found here and here

$txt = "";
foreach($foo->childNodes as $node) {
    if ($node->nodeType == XML_TEXT_NODE) {
        $txt .= $node->nodeValue;
    }
}
