DOM to Parse XML and HTML

2011-04-21T20:36:00.002+10:00

As you have seen we can easily use DOM to manipulate XML and HTML and it's really very very simple.

You use the $node->getElementsByTagName('title')->item(0)->nodeValue , for instance the <title> tag, you can grab the title.

If you have many nodes, you do a for each loop. Say you have 3 list items in <UL>, you can declare $listitems = $doc->getElementsByTagName('li').
Now we have a group of list items, all we have to do now is loop through them and get our stuff. for each ($listitems as $listitem){ $listitem_output = $listitem->item(0)->nodeValue; echo $listitem_output;}
Isn't that great?

Feel free to checkout some posts on how to get attributes using the getAttribute property from DOM, very exciting stuff this is.

RSS PHP: Tutorial #1

2009-07-17T00:33:00.001+10:00

In this first RSS PHP Tutorial, we'll look at how PHP uses XML to parse the RSS file.

Here's an example of parsing a RSS file using the function below.

$rss_tags = array(
‘title’,
‘link’,
‘guid’,
‘comments’,
‘description’,
‘pubDate’,
‘category’,
);
$rss_item_tag = ‘item’;
$rss_url = ‘http://rssphp.blogspot.com/feeds/posts/default’;

$rssfeed = rss_to_array($rss_item_tag,$rss_tags,$rss_url);

print_r($rssfeed);

function rss_to_array($tag, $array, $url) {
$doc = new DOMdocument();
$doc->load($url);
$rss_array = array();
$items = array();
foreach($doc->getElementsByTagName($tag) AS $node) {
foreach($array AS $key => $value) {
$items[$value] = $node->getElementsByTagName($value)->item(0)->nodeValue;
}
array_push($rss_array, $items);
}
return $rss_array;
}
?>

And there you have your own RSS parser. All we did was put the feed items into an array, now you do the rest!
