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

Question

<foo>
  a
  <bar> b </bar>
</foo>

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

How can I get just a (the text from the node, without text from any child nodes)

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;
    }
}

Answer 2

Use firstChild :

$foo->firstChild->textContent;

Answer 3

Try this code

$doc = new DOMDocument();
$doc->loadXML('<root><foo>a<bar>b</bar></foo><foo>bar</foo></root>');
$foos = $doc->getElementsByTagName('foo');
foreach($foos as $v){
   echo $v->firstChild->wholeText.'<br />';
}

The firstChild property of DOMNode returns a DOMText object as there is a "text node" before <bar> in first <foo>
