Question

Using PHP and DOM how do I get the PLACE, ADDRESS, LOCALITY, REGION, POSTAL CODE and COUNTRY from the following code ( part of a web page ).

Since now I have developed a part of the code to get other content. This is the code so far.

$dochtml = new DOMDocument();
$dochtml->loadHTMLfile('');
$xpath = new DOMXpath($dochtml);

$descr = $xpath->query('//div[@class="description"]')->item(0);
    print_r($descr->nodeValue);

$abbr  = $dochtml->getElementsByTagName("abbr")->item(0);
    $title = $abbr->getAttribute("title");
    echo $title;

This is the rest of the code.

<div class="vcard location p">
    <div class="fn org">
        <a href="link here">PLACE</a>
    </div>
    <div class="adr">
        <div class="street-address">ADDRESS<br></div>
        <div>
            <span class="locality">LOCALITY</span>,
            <span class="region">REGION</span>
            <span class="postal-code">POSTAL CODE</span>,
            <span class="country-name">COUNTRY</span>
        </div>
    </div>
</div>

UPDATE

I have a tiny problem with the following, in the page there are a lot of <abbr> tags however the two tags I want with classes dtstart and dtend as below are the only that are inside the #eventDetailInfo. Unfortunately, not all have the second abbr tag with the class=dtend so it gets the first from the “related events”. So my question is how do I restrict it only to this specific id?

<div id="eventDetailInfo">
        <div class="p">
         <div><abbr class="dtstart" title="2012-07-16T21:00:00">Monday, July 16th, 2012</abbr></div>    
         <div><abbr class="dtend" title="2012-08-16T21:00:00">Monday, August 16th, 2012</abbr></div>    
        </div>
</div>

Answer 1

From reading the DOMXPath documentation, my suggested solution is outlined below.

Get elements by class

$nodes = $xpath->query('//div[contains(@class, "street-address")]');

Get elements by ID

$node = $xpath->query('//div[@id="someid"]');

Solution

To extract your values you could use something like (working example):

<?php
$html = '<div class="vcard location p">
    <div class="fn org">
        <a href="link here">PLACE</a>
    </div>
    <div class="adr">
        <div class="street-address">ADDRESS<br></div>
        <div>
            <span class="locality">LOCALITY</span>,
            <span class="region">REGION</span>
            <span class="postal-code">POSTAL CODE</span>,
            <span class="country-name">COUNTRY</span>
        </div>
    </div>
    <div id="eventDetailInfo">
        <div class="p">
         <div><abbr class="dtstart" title="2012-07-16T21:00:00">Monday, July 16th, 2012</abbr></div>    
         <div><abbr class="dtend" title="2012-08-16T21:00:00">Monday, August 16th, 2012</abbr></div>    
        </div>
    </div>
</div>';

$document = new DOMDocument();
$document->loadHTML($html);
$xPath = new DOMXpath($document);

function extractNodeValue($query, $xPath, $attribute = null) {
    $node = $xPath->query("//{$query}")->item(0);
    if (!$node) {
        return null;
    }
    return $attribute ? $node->getAttribute($attribute) : $node->nodeValue;
}

$place = extractNodeValue('div[contains(@class, "fn")]/a', $xPath);
$address = extractNodeValue('div[contains(@class, "street-address")]',$xPath);
$locality = extractNodeValue('span[contains(@class, "locality")]',$xPath);
$region = extractNodeValue('span[contains(@class, "region")]', $xPath);
$postalCode = extractNodeValue('span[contains(@class, "postal-code")]', $xPath);
$countryName = extractNodeValue('span[contains(@class, "country-name")]', $xPath);
$start = extractNodeValue('div[@id="eventDetailInfo"]/div/div/abbr[contains(@class, "dtstart")]', $xPath, 'title');
$end = extractNodeValue('div[@id="eventDetailInfo"]/div/div/abbr[contains(@class, "dtend")]', $xPath, 'title');

var_dump($place, $address, $locality, $region, $postalCode, $countryName, $start, $end);

Output:

string(5) "PLACE" string(7) "ADDRESS" string(8) "LOCALITY" string(6) "REGION" string(11) "POSTAL CODE" string(7) "COUNTRY" string(19) "2012-07-16T21:00:00" string(19) "2012-08-16T21:00:00"
