DOM generating extra children?

[coolbung]

Hello, I have an XML file thus -

<?xml version="1.0" encoding="iso-8859-1"?>

<magazine>
	<gallery>
		<image src="images/back" />
		<image src="images/monstg" />
		<image src="images/tuestg" />
		<image src="images/wedstg" />
		<image src="images/thustg" />
		<image src="images/fristg" />
		<image src="images/monhov"/>
		<image src="images/tuehov"/>
		<image src="images/wedhov"/>
		<image src="images/thuhov"/>
		<image src="images/frihov"/>
	</gallery>
	<color>
    	<image color="0x0F94CA" />
	</color>
    <monday>
	    <mon_txt1>montxt1</mon_txt1>
		<mon_txt2>montxt2</mon_txt2>
		<mon_txt3>montxt3</mon_txt3>
		<url>monurl</url>
	</monday>
    <tuesday>
	    <tue_txt1>tuetxt1</tue_txt1>
		<tue_txt2>tuetxt2</tue_txt2>
		<tue_txt3>tuetxt3</tue_txt3>
		<url>tueurl</url>
	</tuesday>
	<wednesday>
	    <wed_txt1>wedtxt1</wed_txt1>
		<wed_txt2>wedtxt2</wed_txt2>
		<wed_txt3>wedtxt3</wed_txt3>
		<url>wurl</url>
	</wednesday>
	<thursday>
	    <thu_txt1>thutxt1</thu_txt1>
		<thu_txt2>thutxt2</thu_txt2>
		<thu_txt3>thutxt3</thu_txt3>
		<url>thurl</url>
   </thursday>
	<friday>
	    <fri_txt1>fritxt1</fri_txt1>
		<fri_txt2>fritxt2</fri_txt2>
		<fri_txt3>fritxt3</fri_txt3>
		<url>furl</url>
	</friday>


</magazine>

Here's my PHP to read the XML

$xml_file = $mosConfig_absolute_path.'/gallery.xml';
$objDOM = new DOMDocument();
$objDOM->load($xml_file); //make sure path is correct

$xml['image'] = $objDOM->getElementsByTagName("gallery")->item(0);
$tasks = $xml['image']->getElementsByTagName("image");
	foreach ($tasks as $task) {
		$images[] = $task->getAttribute("src");
	}

$xml['color'] = $objDOM->getElementsByTagName("color")->item(0);
$backs = $xml['color']->getElementsByTagName("image");
	foreach ($backs as $back) {
		$colors[] = $back->getAttribute("color");
	}

$xml['mon'] = $objDOM->getElementsByTagName("monday")->item(0)->childNodes;
foreach ($xml['mon'] as $child) {
	$days[] = $child->nodeValue;
}

$xml['tue'] = $objDOM->getElementsByTagName("tuesday")->item(0)->childNodes;
foreach ($xml['tue'] as $child) {
	$days[] = $child->nodeValue;
}

$xml['wed'] = $objDOM->getElementsByTagName("wednesday")->item(0)->childNodes;
foreach ($xml['wed'] as $child) {
	$days[] = $child->nodeValue;
}

$xml['thu'] = $objDOM->getElementsByTagName("thursday")->item(0)->childNodes;
foreach ($xml['thu'] as $child) {
	$days[] = $child->nodeValue;
}

$xml['fri'] = $objDOM->getElementsByTagName("friday")->item(0)->childNodes;
foreach ($xml['fri'] as $child) {
	$days[] = $child->nodeValue;
}

print_r($days);

The print_r function returns more values than i am expecting, It shows that the $days array has 44 values, it should only contain 20.

Any idea why this happens?

As can be seen from looking at the values of the "extra" elements, they're the text nodes that contain the text between, e.g., the "</tue_txt1>" and "<tue_txt2>" tags.

See the list of the DomDocument's properties on the [man]DOM[/man] page.
