Loop through <div> elements using PHP
I have a block of html in a string that is basically a list of divs... Each div has html inside that I 开发者_运维技巧want to parse seperately.
I am having trouble figuring out exactly how to loop over the initial divs.
Can anyone help?
An example of the html:
<div><!-- stuff in here --></div>
<div><!-- stuff in here --></div>
<div><!-- stuff in here --></div>
<div><!-- stuff in here --></div>
In this example I would expect the final code to loop round 4 times and provide me with the contents of each div
This should work (if the HTML is in an external file):
$doc = new DOMDocument();
$doc->loadHTMLFile('test.html');
$divs = $doc->getElementsByTagName('div');
foreach($divs as $n) {
echo $n->nodeValue;
}
And in case of a string containing the HTML, you could do:
$doc = new DOMDocument();
$doc->loadHTML('<html><body><div>A</div><div>B</div><div>C</div><div>D</div></body></html>');
$divs = $doc->getElementsByTagName('div');
foreach($divs as $n) {
echo $n->nodeValue . "\n";
}
which would produce:
A
B
C
D
If it's XHTML, you can use SimpleXML:
$xml = simplexml_load_string($xhtmlstring);
foreach ($xml->div as $d) {
{
//parsing
}
}
