Looping through XML

We want to initialize the XML parser, load the XML, and loop through all elements of the element:

Example

< ?php $xmlDoc = new DOMDocument(); $xmlDoc->load("note.xml"); $x = $xmlDoc->documentElement; foreach ($x->childNodes AS $item) { print $item->nodeName . " = " . $item->nodeValue . " "; } ? >

The output of the code above will be:

#text = to = Tove #text = from = Jani #text = heading = Reminder #text = body = Don't forget me this weekend! #text =

In the example above you see that there are empty text nodes between each element.

When XML generates, it often contains white-spaces between the nodes. The XML DOM parser treats these as ordinary elements, and if you are not aware of them, they sometimes cause problems.
