HTML Parsing

[javawizkid]

Hey, not sure what I'm doing wrong as nothing is displayed in the echo.

 

<?php

  $doc = new DOMDocument();
  $doc->load('http://feeds.feedburner.com/148apps_newest');
  $arrFeeds = array();
  foreach ($doc->getElementsByTagName('description') as $node)
  {
    $itemRSS = array ( 
      'image' => $node->getElementsByTagName('img')->item(0)->nodeValue
      );
    array_push($arrFeeds, $itemRSS);
  }
  
  //print_r($arrFeeds);
  for ($i=0;$i<=40;$i++)
  {
echo $arrFeeds[$i][image];
   	echo ("<br/><br/>");
  }

?>

 

 

print_r($arrFeeds);

outputs blank array items... Hmm

 

Thanks

Add some debug lines inside your foreach loop to check that it is behaving as expected.

But at a glance id say that either the array_push function isn't getting called or an error occurs before the processor reaches that line of code

make sure that error_reporting is set to E_ALL and check your error.log for errors, is turn display_errors ON

I changed the code to

<?php
require_once('simple_html_dom.php');

$html = file_get_html('http://feeds.feedburner.com/148apps_newest');
//echo $html;

// Find all images 
foreach($html->find('img') as $element) 
       echo $element->src . '<br>';

?>

 

to make it simple. It doesn't seem to like reading feeds. It can parse normal html websites like yahoo.com and outputs the image urls as desired. Why won't it parse the url above?

Hi

 

Looking at the source of the page you are grabbing I am not sure it is valid HTML

 

Rather than having:-

 

<img

 

it has

 

<

It wont read it even if I change it to <

 

<?php
require_once('simple_html_dom.php');

$html = file_get_html('http://feeds.feedburner.com/148apps_newest');
//echo $html;

// Find all images 
foreach($html->find('<') as $element) 
       echo $element->src . '<br>';

?>

 

Has it got anything to do with the fact it redirects the url to feed:// instead of http:// ?

Hi

 

Using a normal file_get_contents brings back the contents.

 

Afraid I have no experience of simplehtmldom to suggest anything on that.

 

All the best

What code should I use to grab the img urls then if is feed:// ?

Hi

 

Afraid I don't know. It works fine using file_get_contents, but I presume the html parser you are using requires the other function.

 

All the best
