Question

I am simply building a script that checks a page for certain content, and I am running into a problem with the Zend methods. Here is the function in question:

function parse_html($html) {

    $dom = new Zend_Dom_Query($html);
    $table_rows = $dom->query('tr');

    foreach ($table_rows as $table_row) {
         $table_row->query('td.startTimeDateColumnHeader')->nodeValue;
    }

}

However I am getting this error:

Call to undefined method DOMElement::query()

in regard to this line:

$table_row->query('.startTimeDateColumnHeader')->nodeValue;

Any ideas?

Answer 1

the error is telling you that the php class DOMElement does not have a method named query that is callable.

To explain: you performed a query on a DOM document using Zend_Dom_Query the result returned was in the form of DOMElements and DOMNodes so query() is no longer available.

You’ll probably need to do something like:

$table_row->getAttribute('.startTimeDateColumnHeader');

I may have selected the wrong method, but I hope you get the idea.
