Run XPath over an XPath result within a Foreach loop

[Gu3rr3r0]

I'm working on a project that reads datafeeds like these:\[code\]<?xml version="1.0" encoding="UTF-8"?><producten> <product> <sku><![CDATA[75100192B]]></sku> <price><![CDATA[349.00]]></price> <old_price><![CDATA[499.00]]></old_price> <in_stock><![CDATA[1]]></in_stock> <delivery_time><![CDATA[1 - 2 werkdagen]]></delivery_time> <manufacturer><![CDATA[Kids River]]></manufacturer> <name><![CDATA[Kids River Urban Stroller 3 in 1 Black / Grey Black Frame]]></name> <description><![CDATA[KidsRiver Urban Stroller]]></description> <url><![CDATA[http://www.url.com/]]></url> <categorie><![CDATA[Kinderwagens]]></categorie> <subcategorie><![CDATA[Kinderwagen]]></subcategorie> <model><![CDATA[Kids River Urban]]></model> <collectiejaar><![CDATA[2011]]></collectiejaar> <shipping_price><![CDATA[0.00]]></shipping_price> <image><![CDATA[http://www.url.com/image.jpg]]></image> </product> <product> <sku><![CDATA[Joolz Day Silver / Black - 2012]]></sku> <price><![CDATA[849.00]]></price> <old_price><![CDATA[879.00]]></old_price> <in_stock><![CDATA[1]]></in_stock> <delivery_time><![CDATA[1 - 2 werkdagen]]></delivery_time> <manufacturer><![CDATA[Joolz]]></manufacturer> <name><![CDATA[Joolz Day Silver / Black]]></name> <description><![CDATA[Joolz Day Compleet.]]></description> <url><![CDATA[http://www.url.com/]]></url> <categorie><![CDATA[Kinderwagens]]></categorie> <subcategorie><![CDATA[Kinderwagen]]></subcategorie> <model><![CDATA[Joolz Day]]></model> <collectiejaar><![CDATA[2012]]></collectiejaar> <shipping_price><![CDATA[0.00]]></shipping_price> <image><![CDATA[http://www.url.com/image.jpg]]></image> </product></producten>\[/code\]What I want to do it to make a loop that can read individual products from this feed so I made something like this:\[code\]// Spin up the SimpleXML parser$xml_feed = new SimpleXMLElement($feed_data);$products = $xml_feed->xpath('//producten/product');foreach ($products as $product){ $name = $product->xpath('./name'); $price = $product->xpath('price'); $old_price = $product->xpath('old_price'); $in_stock = $product->xpath('in_stock'); $manufacturer = $product->xpath('manufacturer'); echo print_r( $name); echo var_dump((string) $price[0]); echo var_dump((string) $old_price[0]); echo var_dump((string) $in_stock[0]); echo var_dump((string) $manufacturer[0]); echo "\r\n";}\[/code\]I was wondering if there is a better way to read a xml when using XPath 2 times. One before the loop and the other XPath within the loop. I'm doing it this way because I want to be able to parse all kinds of feeds.I'm a little concerned about the [0] behind the field: $price[0].
