I've already search about this but most of the topics used java language, but i need using DOM in PHP. I wanna extract this element from example.com :
<div id="download" class="large-12 medium-12 columns hide-for-small-only">
<a href="javascript:void(0)" link="https://mediamusic.com/media/mp3/mp3-256/Mas.mp3" target="_blank" class="mp3_download_link">
<i class="fa fa-cloud-download">Download Now</i>
</a>
</div>
How can i get mp3_download_link class from this code using DOM in PHP! as i said i have already search about this but really i confused...
You can use library to parsing DOM. For example: https://github.com/tburry/pquery
Usage:
$dom = pQuery::parseStr($html);
$class = $dom->query('#download a')->attr('class');
You can try file_get_html to parse html
$html=file_get_html('http://demo.com');
and use the below to get all the attributes of anchor tag.
foreach($html->find('div[id=download] a') as $a){
var_dump($a->attr);
}
Let's assume you have this DOM as a string. Then you may use built-in DOM extension to get link you need. Here is the example of a code:
$domstring = '<div id="download" class="large-12 medium-12 columns hide-for-small-only">
<a href="javascript:void(0)" link="https://mediamusic.com/media/mp3/mp3-256/Mas.mp3" target="_blank" class="mp3_download_link">
<i class="fa fa-cloud-download">Download Now</i>
</a>
</div>';
$links = array();
$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($domstring);//here $domstring is a string containing html you posted in your question
$node_list = $dom->getElementsByTagName('a');
foreach ($node_list as $node) {
$links[] = $node->getAttribute('link');
}
print_r(array_shift($links));

I have code like this, and it's fetching data from other website.
require('simple_html_dom.php');
$html = file_get_html("www.example.com");
$info['diesel'] = $html->find(".on .price",0)->innertext;
$info['pb95'] = $html->find(".pb .price",0)->innertext;
$info['lpg'] = $html->find(".lpg .price",0)->innertext;
The html code from other website looks:
<a href="#" class="station-detail-wrapper on text-center active">
<h3 class="fuel-header">ON</h3>
<div class="price">
5,97
<span>zł</span>
</div>
</a>
So if i use echo $info['diesel'] it shows me 5,97 zł. I would like to delete this <span>zł</span> to show price only.
May be you can replace that span tag with blank:
echo $info['diesel']=str_replace("<span>zł</span>","",$info['diesel']);
I want to replace string from specific classes from HTML.
In HTML there is other content which I don't want to change.
In below code want to change data on class one and three only, class two content should be as it is.
I need to this in dynamic way.
<div class="one"> I want to change this </div>
<div class="two"> I don't want to change this </div>
<div class="three"> I want to change this </div>
Dom functions are helpful
php manual
//your html file content
$str = '...<div class="one"> I want to change this </div>
<div class="two"> I don\'t want to change this </div>
<div class="three"> I want to change this </div>... ';
$dom = new DOMDocument();
$dom->loadHtml($str);
$domXpath = new DOMXPath($dom);
//query the nodes matched
$list = $domXpath->query('//div[#class!="two"]');
if ($list->length > 0) {
foreach ($list as $node) {
//change node value
$node->nodeValue = 'Content changed!';
}
}
//get the result
$new_str = $dom->saveHTML();
var_dump($new_str);
I have this code, i get the info but with this i get the data + the link for example
require_once('simple_html_dom.php');
set_time_limit (0);
$html ='www.domain.com';
$html = file_get_html($url);
// i read the first div
foreach($html->find('#content') as $element){
// i read the second
foreach ($element->find('p') as $phone){
echo $phone;
Mobile Pixel 2 -
google << there the link
But i need remove these link, the problem is the next, i scrape this:
<p>the info that i really need is here<p>
<p class="text-right"><a class="btn btn-default espbott aplus" role="button"
href="brand/google.html">Google</a></p>
I read this:
Simple HTML Dom: How to remove elements?
But i cant find the answer
update: if i use this:
foreach ($element->find('p[class="text-right"]');
It will select the links but can't remove scrapped data
You can use file_get_content with str_get_html and replace it :
include 'simple_html_dom.php';
$content=file_get_contents($url);
$html = str_get_html($content);
// i read the first div
foreach($html->find('#content') as $element){
// i read the second
foreach ($element->find('p[class="text-right"]') as $phone){
$content=str_replace($phone,'',$content);
}
}
print $content;
die;
Or here a native version:
PHP-CODE
$sHtml = '<p>the info that i really need is here<p>
<p class="text-right"><a class="btn btn-default espbott aplus" role="button"
href="brand/google.html">Google</a></p>';
$sHtml = '<div id="wrapper">' . $sHtml . '</div>';
echo "org:\n";
echo $sHtml;
echo "\n\n";
$doc = new DOMDocument();
$doc->loadHtml($sHtml);
foreach( $doc->getElementsByTagName( 'a' ) as $element ) {
$element->parentNode->removeChild( $element );
}
echo "res:\n";
echo $doc->saveHTML($doc->getElementById('wrapper'));
Output
org:
<div id="wrapper"><p>the info that i really need is here<p>
<p class="text-right"><a class="btn btn-default espbott aplus" role="button"
href="brand/google.html">Google</a></p></div>
res:
<div id="wrapper">
<p>the info that i really need is here</p>
<p>
</p>
<p class="text-right"></p>
</div>

I have website, where i have posted few images inside particular div :-
<div class="posts">
<div class="separator">
<img src="http://www.example.com/image.jpg" />
<p>Be, where I am today, and i will be one where you will search me tomorrow</p>
</div>
<div class="separator">
<img src="http://www.example.com/imagesda.jpg" />
<p>Be, where I am today, and i will be one where you will search me tomorrow</p>
</div>
.... few more images
</div>
And from my 2nd website, i want to fetch all images on that particular div.. I have below code.
<?php
$htmlget = new DOMDocument();
#$htmlget->loadHtmlFile('http://www.example.com');
$xpath = new DOMXPath( $htmlget);
$nodelist = $xpath->query( "//img/#src" );
foreach ($nodelist as $images){
$value = $images->nodeValue;
echo "<img src='".$value."' /><br />";
}
?>
But this is fetching all images from my website and not just particular div. It also prints out my RSS image, Social icon image, etc.,
Can i specify particular div in my php code, so that it only fetch image from div.posts class.
first give a "id" for the outer div container. Then get it by its id. Then get its child image nodes.
an example:
$tables = $dom->getElementsById('node_id');
$table = $tables->item(1);
//get the number of rows in the 2nd table
echo $table->childNodes->length;
//content of each child
foreach($table->childNodes as $child)
{
echo $child->ownerDocument->saveHTML($child);
}
may be this like will help you. It has a good tutorial.
http://www.binarytides.com/php-tutorial-parsing-html-with-domdocument/
With PHP Simple HTML Parser, this will be:
include('simple_html_dom.php');
$html=file_get_html("http://your_web_site.com");
foreach($html->find('div.posts img') as $img_posts){
echo $img_posts->src.<br>; // to show the source attribute
}
Still reading about PHP Simple HTML Dom parser. And so far, it's faster(in implementation) than regex.
Here is another code that may help. You are looking for
doc->getElementsByTagName
which can help target a tag directly.
<?php
$myhtml = <<<EOF
<html>
<body>
<div class="posts">
<div class="separator">
<img src="http://www.example.com/image.jpg" />
<p>Be, where I am today, and i will be one where you will search me tomorrow</p>
</div>
<div class="separator">
<img src="http://www.example.com/imagesda.jpg" />
<p>Be, where I am today, and i will be one where you will search me tomorrow</p>
</div>
.... few more images
</div>
</body>
EOF;
$doc = new DOMDocument();
$doc->loadHTML($myhtml);
$divs = $doc->getElementsByTagName('img');
foreach ($divs as $div) {
foreach ($div->attributes as $attr) {
$name = $attr->nodeName;
$value = $attr->nodeValue;
echo "Attribute '$name' :: '$value'<br />";
}
}
?>

Also the answer here can provide further insights
Not finding elements using getElementsByTagName() using DomDocument
I want to get a specific tag from url, from example:
If I have this content:
<div id="hey">
<div id="bla"></div>
</div>
<div id="hey">
<div id="bla"></div>
</div>
And I want to get all divs with the id "hey", ( i think its with preg_match_all ), How can I do that?
The content inside the tag can be changed.
I recommend use DOMDocument class instead of regular expressions (is less resource consumer and more clear IMHO).
$content = '<div id="hey">
<div id="bla"></div>
</div>
<div id="hey">
<div id="bla"></div>
</div>';
$doc = new DOMDocument();
#$doc->loadHTML($content); // # for possible not standard HTML
$xpath = new DOMXPath($doc);
$elements = $xpath->query("//div[#id='hey']");
/*#var $elements DOMNodeList */
for ($i=0;$i<$elements->length;$i++) {
/*#var $curr_element DOMElement */
$curr_element = $elements->item($i);
// Here do what you want with the element
var_dump($curr_element);
}
If you want to get the content from an URL you can use this line instead to fill the variable $content:
$content = file_get_contents('http://yourserver/urls/page.php');
