Need Help with DOMXpath

[hieK]

so i am trying to make my api for a website, and started coding a script for it.

 

so far it looks like this

 

<?php

 

$ch = curl_init("http://www.gustos.ro/retete-culinare/saratele-din-faina-de-naut.html");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$rt = curl_exec($ch);

 

$dom = new DOMDocument();

@$dom->loadHTML($rt);

 

$xpath = new DOMXpath($dom);

 

// title ("//h1[@class=textLarge7 extratextLarge7]/text()")

 

$titleQuery = $xpath->query("//h1[@class=textLarge7 extratextLarge7]/text()");

echo $titleQuery;

 

 

 

the problem is that when i try to echo it it wont give me the title ( only an error on line 17, that is the last line )

 

if it helps you when i try to execute print_r it gives me DOMNodeList Object ( )

 

Sorry for my bad english, its not my native language

index.php

I`ve figured it out, it was because of the list, so i had to use node->nodeValue and worked

So now i have another problem,

 

<ul class="listType1 marginTop1">

<li itemprop="ingredients">13/4 pahar faina de naut</li>

<li itemprop="ingredients">3/4 lingurita de sare</li>

<li itemprop="ingredients">3/4 lingurita cardamon macinat marunt</li>

<li itemprop="ingredients">1/2 lingurita piper negru macinat</li>

<li itemprop="ingredients">11/2 pahare de apa</li>

<li itemprop="ingredients">4 linguri ulei de masline</li>

</ul>

 

i cant figure out how to write the xpath query

 

$ingredientsQuery = $xpath->query("//ul[@class=listType1 marginTop1]/text()"); but how do i integrate the li ?

Dude xpath and DOM are a pain! Try the library Querypath (its a wrapper around DOMDocument). It takes the pain out of these things.
