Printing content of a XML file using XML DOM 

<?xml version="1.0" encoding="UTF-8"?>
<colors>
    <apple>red</apple>
    <banana>yellow</banana>
    <grape>purple</grape>
</colors>

Since fruit names (tag names) are unknown, I'm trying to get all tag names and values with childNodes of <colors>

$dom = new DOMDocument();
$dom->load("colors.xml");
$dom->preserveWhiteSpace = false;

$root = $dom->getElementsByTagName("colors")->item(0);
$colors = $root->childNodes;

echo "<p>".$colors->length."</p>";

foreach($colors as $color) {
    echo "<p>".$color->nodeName." - ".$color->nodeValue."</p>";
}

$colors->length returns 7 instead of 3, and the result:

#text - 
apple - red
#text - 
banana - yellow
#text - 
grape - purple
#text -

Can someone please explain what are those #text -? And what's wrong with my code? Thanks.

update

If I manually remove tabs and returns from the xml file, make the whole file into one line, #text - are gone. But I don't think that's the way it should be.
