PHP - digging farther down in a Xpath query

Try this :

$url =
$output = file_get_contents($url);
$doc = new DOMDocument();

libxml_use_internal_errors(true); //Supress
Warnings for HTML5 conversion issue
libxml_use_internal_errors(false); //Start Showing

$xpath = new DOMXpath($doc);

foreach ($xpath->query('//h1') as $e) {
    $country = trim($e->textContent);

$e) as $h4) {
        $state = trim($h4->textContent);

$h4) as $a) {
                $town = $a->textContent;
                $attributeNodeMap =
                $nodeAttribute =
                $href =

                echo "$country - $state - $town -


So that's how I did it.
First of all I'm using firefox with firebug and firepath (i guess you can find similar tools for other web browser).
This tools let me try some Xpath without writing PHP code.

With firebug you can see the DOM tree which is really useful to know what you can reach, ... and then try Xpath with firepath

To start i selected all H1 nodes //h1 in the document and then you need to get all H4 for each H1 to get state but unfortunately H4 node is not a child of H1 node, so you need to find another way to reach it if you want to start from H1 node.

If you look at DOM tree you will see that a div (which contains H4 node) is one of the next sibling of H1 node, so let's select it following-sibling::div[1] (this is the div <div class="colmask"> for the current h1 node only).
We want all H4 nodes //h4 then we've got following-sibling::div[1]//h4

Now we do the same thing for the <a href...> for each H4, so we select all A nodes in all LI nodes which are in the next sibling UL of H4 following-sibling::ul[1]//li/a

I hope this is understandable (and useful of course) and sorry for the mistakes, English is not my language.

Is there a way to ignore case when performing an xpath query
One option is to use XPath translate to convert uppercase letters to lowercase. In that case your expression would look like: var xpath = '//*[translate(name(), "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "abcdefghijklmnopqrstuvwxyz") = "filter"]'; There are some nicer XPath 2.0 methods like matches and similar, but no browser currently supports it:

how to split xml using xpath in perl?
The reason you're having difficult is because what you're doing is extracting a subset from an XML doc, but then trying to also include some of the stuff from the 'parent'. Pulling your 'delts' out would be fairly straightforward I would be wanting to use XML::Twig with this - this is a perfect place to use a twig handler. I'd be thinking something along the lines of (and apologies, this do

You could just point to b first, then inside the loop, each b, point it to c and d: $result = $xml->xpath('//b'); foreach ($result as $val) { echo $val->c . $val->d . "<br>"; }

Extract value from xpath array
Use the ->item() method on the result to access the DOM nodes that your XPath query returns. Also you should rather use the query() method when you want to run an XPath query. I've never really understood the purpose of using evaluate(). $xpath = new DOMXPath($dom); $results = $xpath->query('//*[@itemprop="price"]'); echo $results->item(0)->nodeValue; DOMXPath->query() returns an
