php DomDocument : Match each nodeValue, add attribute to its nodeName if condition satisfies

Question

Check for each text node whether or not it exists in DataBase, if it does then add a class to its Element node.

I have tried do it the following way :

function extractText($node) {
    if (XML_TEXT_NODE === $node->nodeType || XML_CDATA_SECTION_NODE === $node->nodeType) {

// am considering that Login is the word that exists in DB
            if ($node->nodeValue == "Login"): 
                $node->setAttribute("class", "translated");
                return $node->nodeName;
            endif;
        } else if (XML_ELEMENT_NODE === $node->nodeType || XML_DOCUMENT_NODE === $node->nodeType
                || XML_DOCUMENT_FRAG_NODE === $node->nodeType) {
            if ('script' === $node->nodeName || 'style' === $node->nodeName)
                return '';

        $text = '';
        foreach ($node->childNodes as $childNode) {
            $text .= extractText($childNode);
        }
        return $text;
    }
}

$doc = new DomDocument;
$doc->loadHTMLFile('test.html');

//var_dump(extractText($doc->getElementsByTagName('body')->item(0)));
echo extractText($doc->getElementsByTagName('body')->item(0));

But it gives Error message.

Fatal error: Call to undefined method DOMText::setAttribute()

Fatal error: Call to undefined method DOMText::setAttribute()

Well, let's look at the code.

if (XML_TEXT_NODE === $node->nodeType || XML_CDATA_SECTION_NODE === $node->nodeType) {
// am considering that Login is the word that exists in DB
    if ($node->nodeValue == "Login"): 
        $node->setAttribute("class", "translated");
        return $node->nodeName;
    endif;
} /* else ... */

You're asking exclusively for text or CDATA nodes, then you're trying to set an attribute ... on the text. This won't work. Text nodes can't have attributes.

You need to get to the element containing the text and add the attribute there. Because DOMText inherits from DOMNode, you can inspect the parentNode property and probably get an element back.

! thanks for the reply, but i tried to do this way too : $node->nodeName->setAttribute("class", "translated"); but of no use – atif Dec 18 '12 at 10:51

Why would you try `nodeName`? `nodeName` is a *string*. It is not a reference an element. Please refer to the linked manual pages. – Charles Dec 18 '12 at 10:52
charles can you modify your answer plz so that i can make it to work, currenlty am not able to do that – atif Dec 18 '12 at 11:16
No, I will not provide copy/paste code for you. – Charles Dec 20 '12 at 04:52
