Cannot get get right value with XPath

Question

I'm using a src which collects data and works as an API. The website it takes info from had been redone and some stuff work, some don't.

PHP :

protected $namexpath = ".//h1[contains(@itemprop,\"name\")]/a";

Works with HTML Source :

 <h1 itemprop="name" class="fn itemTitle">
    <a title="https://www.paginegialle.it/altopascio-lu/lotto-ricevitorie/lucky-planet-duro-anastasia-tabaccheria-ricevitori" href="https://www.paginegialle.it/altopascio-lu/lotto-ricevitorie/lucky-planet-duro-anastasia-tabaccheria-ricevitori">
        Lucky <strong>Planet</strong> - Duro Anastasia <strong>Tabaccheria</strong> Ricevitoria Lotto
    </a>
</h1>

But this is not working:

PHP :

protected $telephonexpath = ".//div[@class=\"hidden-phone-elem visiblePhone\"]/span";

HTML Source :

<section itemscope="" itemtype="https://schema.org/LocalBusiness" class="vcard listElement   flFree " data-user="teverola-ce/bar/rivendita-generi-monopolio-n.-2-tozzi-iolanda" data-id="4" data-fl_free="true" data-cd_opec="GU01WAAW" data-cd_aggregazione="23787370" data-cd_id_sede="E57901ED-8833-A2AD-E040-A8C08D264C56">

I edited and I am adding some text because It won't let me finalize edit since it says too much code, I fixed the first part and changed from span to h1

Answer 1

The Xpath does not match the HTML. The relevant fragment seems to be:

<div class="hidden-phone-elem">
    <div class="btn btn-yellow btn-show-phone" data-pag="mostra telefono" data-context="listing">
        <span>MOSTRA TELEFONO</span>
    </div>
    <div class="btn btn-hidden-phone">
        <span class="phIco "></span>
        <span class="phone-label">081 5034556</span>
    </div>
</div>

The div has only the class hidden-phone-elem and two descendant span s. Xpath 1.0 has no token selector function, but it can be emulated with string functions.

• normalize-space() - replace all whitespace sequences with a single space, trim
• concat() - concatenate strings
• contains() - look for substring

The trick is to normalize the attribute to something like classToMatch otherClass and look if that contains classToMatch . (Take note of the spaces at the start/end).

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

$expression = 'string(
    //div[
      contains(concat(" ", normalize-space(@class), " "), " hidden-phone-elem ")
    ]
    //span[
      contains(concat(" ", normalize-space(@class), " "), " phone-label ")
    ]
)';

var_dump($xpath->evaluate($expression));

Output:

string(11) "081 5034556"
