DOM

[niche]

I'm learning about the way php works its DOM (http://php.net/manual/en/book.dom.php). I'd like to display the contents of $items using a learning script that I created from the example at http://php.net/manua...elist.item.php.

<?php$file = file_get_contents('http://www.imdb.com/find?q=star+trek&s=all');$DOM = new DOMDocument();$DOM->load($file); $items = $DOM->getElementsByTagName('a'); for ($i = 0; $i < $items->length; $i++) {	echo $items->item($i)->nodeValue . "\n";}?>

There's plenty of anchors at this imdb page and there are no warnings or errors. Why do you suppose there's no display?

I think the load method is for xml files. For html pages, try: $DOM->loadHTMLFile(); You don't need the file_get_contents() function. Just enter the address in the loadHTMLFile function as a string. ie: $DOM->loadHTMLFile('http://www.w3schools.com');

Thanks Don E. That function worked much better, but it threw seven warnings. They all said the same thing with different line refs: Warning: DOMDocument::loadHTMLFile() [domdocument.loadhtmlfile]: Unexpected end tag : a in http://www.w3schools.com, line: 616 in E:\wamp\www\test_121209.php on line 3 I used the w3schools site. Do you suppose they they have a few unclosed anchors, or does something else come to mind? I know I can turn them off. Just interested is all. Current script:

<?php$DOM = new DOMDocument();$DOM->loadHTMLFile('http://www.w3schools.com');$items = $DOM->getElementsByTagName('a');for ($i = 0; $i < $items->length; $i++) {	echo $items->item($i)->nodeValue . '<br/>';}?>

Welcome. I got the same warnings too when I tried www.w3schools.com. I am not entirely sure if it is because of unclosed anchors, but it may be so. I just ran their site through w3 validator and got some warnings/errors. If you try http:www.w3.org ( $DOM->loadHTMLFile('http://www.w3.org'); ) though, you will get no warnings and get the results you're looking for.

Very interesting. Thanks again. You made this a very good topic. It's time to take the garbage to the curve and hit the rack.

http://in3.php.net/manual/en/function.libxml-use-internal-errors.php this function will disable html validation errors. you can also pass the file to tidy http://php.net/tidy to clean out the page.
