How to get count of XML nodes in PHP using DOMDocument?

Using the snippet below, how can I get the number of FIELD nodes before I iterate through the collection for output?

Many thanks!
$form = new DOMDocument() or die("error");
$form->load("ContactForm.xml");
$fields = $form->getElementsByTagName("Field");
 
// xml...
 
<ContactForm>
	<Field>
		<Label>First Name</Label>
		<Name>contact_first_name</Name>
		<Type>FIELD</Type>
		<Required>1</Required>		
	</Field>
	<Field>
		<Label>Last Name</Label>
		<Name>contact_last_name</Name>
		<Type>FIELD</Type>
		<Required>1</Required>		
	</Field>
        ...
        ...
</ContactForm>

DOMDocument->getElementsByTagName() returns a DOMNodeList.  All DOMNodeLists possess, as a read-only value, a property called "length".

After line 3, you can use `$fields->length` to check how many Field elements were returned.
