I have a remote file for example, which contains the ff:
Code:
...bunch of markups...
<div id="block-i-need-to-get">
<div>some content</div>
<div>some more content</div>
</div>
...more bunch of markups...
what i need is that particular code block only, and i understand that there's a preg_match() function that can be used for this, the problem is that, i don't know how to construct the code that will do it... any tips/links/snippets?
thanks in advance.

[quote author="TheFuzzy0ne" date="1241415860"]I think you'd be better off traversing the DOM -

Hope this helps.[/quote]
Helps a lot! Thank you, and that link is chock-full of PHP goodness! :cheese:
BTW, how come codeigniter doesn't have a library/helper for this?

Because the DOM is built in into PHP, so why make an library for it that already exists ?

I think he was maybe refering more to a wrapper class... although it looks so easy to use, there probably isn't any need

Haha, it's really easy to use, you can parse HTML, XML etc
Working with the DOM is really simple (in this case we use an XML file):
Initialize it:
Code:
$DOM = new DOMDocument();
Load a file
Code:
$DOM->load("yourfile.xml");
Get a certain XML element with the name 'template_info'
Code:
$template_info = $DOM->getElementsByTagName("template_info");
Loop through each item
Code:
foreach($template_info as $template_infos) {
//De auteur
$author = $template_infos->getElementsByTagName('author');
$author = $author->item(0)->nodeValue;
//De naam van het thema
$name = $template_infos->getElementsByTagName('name');
$name = $name->item(0)->nodeValue;
//De website van de eigenaar van het thema
$website = $template_infos->getElementsByTagName('website');
$website = $website->item(0)->nodeValue;
//De copyrights
$copyright = $template_infos->getElementsByTagName('copyright');
$copyright = $copyright->item(0)->nodeValue;
//De licentie van het thema
$license = $template_infos->getElementsByTagName('license');
$license = $license ->item(0)->nodeValue;
//De beschrijving
$desc = $template_infos->getElementsByTagName('description');
$desc = $desc ->item(0)->nodeValue;
}
I used that code to parse an .xml file which would contain info about a template

Don't worry, it doesn;t make you a n00b lol
With 5344 documented
PHP functions no one is expected to know them all
(and no, I didn't count them all manually
)

@yorick: thanks for the code man, nice to have something to start with... one question, is it possible to maybe parse a remote file? e.g.
Code:
$remote = 'http://example.com/data.html';
$DOM = new DOMDocument();
$DOM->load($remote);
$content = $DOM->getElementById('somediv');
and do either
Code:
echo $content; OR
print_r($content);
i tested the above, but i get some parsing errors when using $dom->load():
Code:
Warning: DOMDocument::loadHTMLFile() [domdocument.loadhtmlfile]: error parsing attribute name in http://example.com/forecast.html, line: 19 in E:\localweb\projects\test\getfile.php on line 5
and a blank page if i use $dom->loadHTML()... anyway, appreciate the help. :lol:
@dam1an: 5,344?! and all of those are built-in?! :wow:
[eluser]Dam1an[/eluser]
@nubianxp: Yeah they're all the built in PHP functions, then there's another million extra user created functions
PHP has grown to be huge!!!
