php - How to parse xml with xpath and retrieve an array of elements?

973

I'm trying to get this thing done for about 3 hours so I would appreciate any help. I need to parse the xml below and extract the 'title', 'description', 'phone', 'address', 'price', 'pictures', 'attributes'. I've managed to extract the title, description and phone.

I can't get the address(location) latitude and longitude individually. I get -1.3054552.7008 instead of latitude: -1.3054, longitude: 552.7008.

I don't know how to extract the pictures. It should be an array.

I don't know how to extract the attributes. It should be an array.

Here is the code I have:

$adXml = file_get_contents('ad.xml');

$dom = new DOMDocument();
$dom->loadXml($adXml);
$xpath = new DOMXpath($dom);
$xpath->registerNamespace('ad', 'http://www.domainclassifiedsgroup.com/schema/ad/v1');
$xpath->registerNamespace('attribute', 'http://www.domainclassifiedsgroup.com/schema/attribute/v1');
$xpath->registerNamespace('pic', 'http://www.domainclassifiedsgroup.com/schema/picture/v1');
$xpath->registerNamespace('location', 'http://www.domainclassifiedsgroup.com/schema/location/v1');

#$ads = $xpath->evaluate('/ad:ad/ad:ad', NULL, FALSE);

$title = $xpath->evaluate('string(ad:title)', NULL, FALSE);
$description = $xpath->evaluate('string(ad:description)', NULL, FALSE);
$phone = $xpath->evaluate('string(ad:phone)', NULL, FALSE);

//the price is a kind of array so we ened to remove GBP
$price = $xpath->evaluate('string(ad:price)', NULL, FALSE);
$price = str_replace('GBP', '', $price);

//$pictures = $xpath->evaluate('string(pic:pictures)', NULL, FALSE);
$pictures = '?';
$attributes = '?';
$address = $xpath->evaluate('string(ad:ad-address)', NULL, FALSE);  // why is not array ?

The xml is below

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ad:ad xmlns:types="http://www.domainclassifiedsgroup.com/schema/types/v1" xmlns:cat="http://www.domainclassifiedsgroup.com/schema/category/v1" xmlns:loc="http://www.domainclassifiedsgroup.com/schema/location/v1" xmlns:ad="http://www.domainclassifiedsgroup.com/schema/ad/v1" xmlns:feat="http://www.domainclassifiedsgroup.com/schema/feature/v1" xmlns:attr="http://www.domainclassifiedsgroup.com/schema/attribute/v1" xmlns:pic="http://www.domainclassifiedsgroup.com/schema/picture/v1" xmlns:user="http://www.domainclassifiedsgroup.com/schema/user/v1" xmlns:rate="http://www.domainclassifiedsgroup.com/schema/rate/v1" xmlns:reply="http://www.domainclassifiedsgroup.com/schema/reply/v1" xmlns:feed="http://www.domainclassifiedsgroup.com/schema/feed/v1" xmlns:order="http://www.domainclassifiedsgroup.com/schema/order/v1" xmlns:payment="http://www.domainclassifiedsgroup.com/schema/payment/v1" locale="en_GB" version="1.17" id="1047060901">

Update : Trying to retrieve the images using 

$pictures = $xml->xpath("//pic:pictures/pic:picture");

foreach ($pictures as $picture) {

  $pic = (string)$picture->xpath("pic:link/@extrabig")[0];

  print_r($pic);
}

doesn't work.

Answer

Solution:

If you cast an element in xpath using string(), number() or boolean() it will cast the node value of that element. That means all text content inside that element and its descendants.

So if you use the expressionstring(ad:ad-address) it returns the content of both child nodes types:longitude and types:latitude. To get them separate you need to use separate expressions to fetch the longitude/latitude values.

$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);
$xpath->registerNamespace('ad', 'http://www.domainclassifiedsgroup.com/schema/ad/v1');
$xpath->registerNamespace('types', 'http://www.domainclassifiedsgroup.com/schema/types/v1');

var_dump(
  [
    'lng' => $xpath->evaluate('number(/ad:ad/ad:ad-address[1]/types:longitude)', NULL, FALSE),
    'lat' => $xpath->evaluate('number(/ad:ad/ad:ad-address[1]/types:latitude)', NULL, FALSE)
  ]
);

Output:

array(2) {
  ["lng"]=>
  float(-1.30545)
  ["lat"]=>
  float(52.7008)
}

If you want to handle multiple elements you fetch a list first, iterate it and use expressions with a context node. The context node is the second argument of evaluate(). If you want attributes/content from the element you iterate you can use the just read them using getAttribute() or $nodeValue.

$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);
$xpath->registerNamespace('ad', 'http://www.domainclassifiedsgroup.com/schema/ad/v1');
$xpath->registerNamespace('pic', 'http://www.domainclassifiedsgroup.com/schema/picture/v1');

$result = [];
$nodes = $xpath->evaluate('/ad:ad/pic:pictures/pic:picture', NULL, FALSE);
foreach ($nodes as $node) {
  $row = [];
  foreach ($xpath->evaluate('pic:link', $node, FALSE) as $linkNode) {
    $row[$linkNode->getAttribute('rel')] = $linkNode->getAttribute('href'); 
  }
  $result[] = $row;
}

var_dump($result);

Output:

array(8) {
  [0]=>
  array(5) {
    ["extrabig"]=>
    string(102) "http://i.domainimg.com/00/s/NTMxWDgwMA==/z/C-QAAMXQWzNSeR-h/$(KGrHqJHJFEFJ0Ie)pzWBSeR-hK5zw~~48_80.JPG"

Answer

Solution:

here is an alternative to xpath if you need it asap. 

<?php

    $path = @file_get_contents('ad.xml');
    $xml = @simplexml_load_string($path);
    $namespaces = $xml->getNameSpaces(true);

    $ad = $xml->children($namespaces['ad']);
    $description = (string)$ad->description;
    echo $description;

    $title = (string)$ad->title;
    echo $title;

    $address = $ad->{'ad-address'}->children($namespaces['types']);
    echo $address->longitude;
    echo $address->latitude;

    $phone = (string)$ad->phone;
    echo $phone;

    $price = $ad->price->children($namespaces['types']);
    echo $price;

    $photos = $xml->children($namespaces['pic']);
    $pictures = $photos->children('pic');

    foreach($photos->pictures as $pictures)
    {
        foreach($pictures as $photo) 
        {
            foreach ($photo->link as $link)
            {
                $att = $link->attributes();
                if ($att['rel'] == 'extrabig')
                {
                    echo $att['href'];
                }
            }
        }
    }

    ?>

The following code outputs the following. It was a rush job. I am sure you can refactor it and make it parse the feed dynamically.

Answer

Solution:

That's a hell of a XML...

Here is some code, usingsimplexml andxpath. Sorry I'm not that much intoDOM. This example requires PHP >= 5.4.

$xml = simplexml_load_string($x); // assume XML in $x

$title = (string)$xml->xpath("//ad:ad/ad:title")[0];
$price = (string)$xml->xpath("//ad:ad/ad:price/types:amount")[0];
$attributes = $xml->xpath("//attr:attributes/attr:attribute");

echo $title . PHP_EOL;
echo $price. PHP_EOL;

foreach ($attributes as $a) {
    $label = (string)$a->xpath("@localized-label")[0];
    $value = (string)$a->xpath("./attr:value")[0];
    echo "$label: $value" . PHP_EOL;
}

You can access the other nodes according to these examples.

See it working: https://eval.in/97091

Comments:

  • makes use of xpath without registering the namespaces.
  • (string) = casting the xpath-results to string instead of getting objects as results
  • ...)[0]; = array dereferencing, requires PHP >= 5.4

UPDATE: get the@rel='extrabig'@href of the<pic:link> nodes:

$pictures = $xml->xpath("//pic:pictures/pic:picture/pic:link[@rel = 'extrabig']/@href");
$pictures = array_map('strval', $pictures); // converts every element to string
foreach ($pictures as $pic) echo $pic . PHP_EOL;
