awesome article! however I was trying to run this piece of code against the following xml that is returned from ebay and I did not get any response. It seems like the SimpleXML xpath does not like some of the queries or at least I couldn’t make it work. It does, however work if you only run the xpath query in a xpath query test tools!

Very good condition with no writing! Fast shipping!

// the php code

$xml = simplexml_load_file(the xml file);
$xml->registerXpathNamespace(‘ebay’,'urn:ebay:apis:eBLBaseComponents’);
try{

//this should give me the sorename that has the current price of 1.98
$resp = $xml->xpath(“//ebay:CurrentPrice[.=1.98]/following-sibling::Storefront/StoreName”);

} catch (Exception $e)
{
echo $e->getMessage();
}

var_dump($resp);//returns nothing

any idea?

Your English jammed my brain. I fixed it for you.

…

A few years back when I first read book about XML I could not understand what the hype was all about. It was some markup language that stores data in well organized way. I also remember parsing XML files in PHP a few years back. The whole file was read using fread() and then a programmer had to create some kind of parser to process XML file. IT was completely ridiculous. Sure ActionScript, probably Java and some other languages already had classes for parsing XML files, but that was not the case for PHP. So I thought that this was a technology that did not deserve a second look.

Fast Forward to today. I read an article covering interesting XML features like XPath, XPoiner, XInclude nad XSLT. Today, I want to introduce you to one of them: XPath. I guess it’s name reveals what it is all about. Basically XPath is a language that allows to localize and fetch information from an XML tree.

First we need a basic XML document, nothing too complicated but nothing too simple either, to show the power of XPath.
