I tried that. $Element->hasChildNodes() returns true for just about everything except tags like <br> and <img> that have no corresponding </br> or </img> because the content that appears between <p> and </p>, for example, apparently counts as a child node, even though they're not HTML tags. So, if you have: <p>Foo!</p> when you look at $Element->hasChildNodes() for the <p> tag, you will get "true", and $Element->childNodes->length is equal to "1", even though "Foo!" isn't an HTML tag. Interestingly though, when you iterate through the tree, you get the <p> tag as one of the elements, but you never get a text-only element that has that <p> as a parentNode. In fact, get_class($Element) always returns DOMElement, even on the text-only nodes, which I would have expected to be DOMText elements...but I guess not. So I'm wondering why $Element->hasChildNodes() would return true, but iterating through the DOM tree returns no elements that have that $Element as a parentNode. What's more, looking at $Element->childNodex->length isn't too helpful, because, for example: <h2><a name="bar"></a>Foo</h2> returns two child nodes, neither of which has "Foo" for its textContent.
