that depends on which php version you are using. with php5 there might be a hint in the DomDocument definition on www.php.net, this could reduce it to something like getElementsByTagName().length (javascript).

Nevertheless, there is a count() function in XSL:
Expand|Select|Wrap|Line Numbers
  1. <xsl:value-of select="count(//product)" />
would output the number of all <product> elements. You can certainly process such a stylesheet with php and you get your count number.

You could of course always try to use a regular expression. The preg_match_all function will search for a given pattern and return the number of matches it finds.

I think there is a easy way for you. Have you ever tried DOMDocument

[PHP]$xml= "products.xml";
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
$product = $xmlDoc->getElementsByTagName("product");
$numOfproducts = $product->length;
echo $numOfproducts;[/PHP]

This will print the output as 3 for your xml file in In this thread :D

Good luck!
