I need to print out my array, but print_r($test) doesn't work at last...
Here is a simple code :
$code = '<html><head></head><body><div class="list"><img src="http://google.com/564308080517287.jpg" alt="my title"></div></body></html>'; // Code is simplified here, but imagine you've got much more contents inside
$doc = new DOMDocument();
$doc->loadHTML( $code );
//
$test = array();
foreach($doc->getElementsByTagName('div') as $div){
if($div->getAttribute('class') == "list"){
$ads_count = $div->getElementsByTagName('a')->length;
for ($i=0; $i<=$ads_count; $i++) {
$ad = $div->getElementsByTagName('a')->item($i);
$ad_img = trim($ad->getElementsByTagName('img')->item(0)->getAttribute('src'));
$test[$i]['img'] = $ad_img;
}
}
}
print_r($test); // doesn't work !!
Any idea ?
<?php
$code = '<html><head></head><body><div class="list">
<img src="http://google.com/564308080517287.jpg" alt="my title"></div></body></html>'; // Code is simplified here, but imagine you've got much more contents inside
$dom = new DOMDocument();
$dom->loadHtml($code);
$selector = new DOMXPath($dom);
$parceiltable = $selector->query("//div[#class='list']/a/img");
foreach($parceiltable as $key=>$tds){
$test[]['img'] = $tds->getAttribute('src');
}
print_r($test);
?>

Here is my code:
$res = file_get_contents("http://www.lenzor.com/photo/search/index/type/user/%D8%B9%D9%84%DB%8C//text/%D9%81%D8%A7%D8%B7%D9%85%D9%87");
$doc = new \DOMDocument();
#$doc->loadHTMLFile($res);
$xpath = new \DOMXpath($doc);
$links = $xpath->query("//ul[#class='user_box']/li");
$result = array();
if (!is_null($links)) {
foreach ($links as $link) {
$href = $link->getAttribute('class');
$result[] = [$href];
}
}
print_r($result);
Here is the content I'm working on. I mean it's the result of echo $res.
Ok well, the result of my code is an empty array. So $links is empty and that foreach won't be executed. Why? Why //ul[#class='user_box']/li query doesn't match the DOM ?
Expected result is an array contains the class attribute of lis.
Try this, Hope this will be helpful. There are few mistakes in your code.
1. You should search like this '//ul[#class="user_box clearfix"]/li' because class="user_box clearfix" class attribute of that HTML source contains two classes.
2. You should use loadHTMLinstead of loadHTMLFile.
<?php
ini_set('display_errors', 1);
libxml_use_internal_errors(true);
$res = file_get_contents("http://www.lenzor.com/photo/search/index/type/user/%D8%B9%D9%84%DB%8C//text/%D9%81%D8%A7%D8%B7%D9%85%D9%87");
$doc = new \DOMDocument();
$doc->loadHTML($res);
$xpath = new \DOMXpath($doc);
$links = $xpath->query('//ul[#class="user_box clearfix"]/li');
$result = array();
if (!is_null($links)) {
foreach ($links as $link) {
$href = $link->getAttribute('class');
$result[] = [$href];
}
}
print_r($result);
Here is what I am trying to achieve : retrieve all products on a page and put them into an array. Here is the code I am using :
$page2 = curl_exec($ch);
$doc = new DOMDocument();
#$doc->loadHTML($page2);
$nodes = $doc->getElementsByTagName('title');
$noders = $doc->getElementsByClassName('productImage');
$title = $nodes->item(0)->nodeValue;
$product = $noders->item(0)->imageObject.src;
It works for the $title but not for the product. For info, in the HTML code the img tag looks like this :
<img alt="" class="productImage" data-altimages="" src="xxxx">
I have been looking at this (PHP DOMDocument how to get element?) but I still don't understand how to make it work.
PS : I get this error :
Call to undefined method DOMDocument::getElementsByclassName()
I finally used the following solution :
$classname="blockProduct";
$finder = new DomXPath($doc);
$spaner = $finder->query("//*[contains(#class, '$classname')]");

Linking this answer as it helped me the most with this problem.
function getElementsByClass(&$parentNode, $tagName, $className) {
$nodes=array();
$childNodeList = $parentNode->getElementsByTagName($tagName);
for ($i = 0; $i < $childNodeList->length; $i++) {
$temp = $childNodeList->item($i);
if (stripos($temp->getAttribute('class'), $className) !== false) {
$nodes[]=$temp;
}
}
return $nodes;
}
Theres the code and heres the usage
$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($html);
$content_node=$dom->getElementById("content_node");
$div_a_class_nodes=getElementsByClass($content_node, 'div', 'a');
function getElementsByClassName($dom, $ClassName, $tagName=null) {
if($tagName){
$Elements = $dom->getElementsByTagName($tagName);
}else {
$Elements = $dom->getElementsByTagName("*");
}
$Matched = array();
for($i=0;$i<$Elements->length;$i++) {
if($Elements->item($i)->attributes->getNamedItem('class')){
if($Elements->item($i)->attributes->getNamedItem('class')->nodeValue == $ClassName) {
$Matched[]=$Elements->item($i);
}
}
}
return $Matched;
}
// usage
$dom = new \DOMDocument('1.0');
#$dom->loadHTML($html);
$elementsByClass = getElementsByClassName($dom, $className, 'h1');
I'm working with a DOM parser and I'm having issues. I'm basically trying to grab the href within the tag that only contain the class ID of 'thumbnail '. I've been trying to print the links on the screen and still get no results. Any help is appreciated. I also turned on error_reporting(E_ALL); and still nothing.
$html = file_get_contents('http://www.reddit.com/r/funny');
$dom = new DOMDocument();
#$dom->loadHTML($html);
$classId = "thumbnail ";
$div = $html->find('a#'.$classId);
echo $div;
I also tried this but still had the same result of NOTHING:
include('simple_html_dom.php');
$html = file_get_contents('http://www.reddit.com/r/funny');
$dom = new DOMDocument();
#$dom->loadHTML($html);
// grab all the on the page
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
$ret = $html->find('a[class=thumbnail]');
echo $ret;
You were almost there:
<?php
$dom = new DOMDocument();
#$dom->loadHTMLFile('http://www.reddit.com/r/funny');
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a[contains(concat(' ',normalize-space(#class),' '),' thumbnail ')]");
var_dump($hrefs);
Gives:
class DOMNodeList#28 (1) {
public $length =>
int(25)
}
25 matches, I'd call it success.
This code would probably work:
$html = file_get_contents('http://www.reddit.com/r/funny');
$dom = new DOMDocument();
#$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$hyperlinks = $xpath->query('//a[#class="thumbnail"]');
foreach($hyperlinks as $hyperlink) {
echo $hyperlink->getAttribute('href'), '<br>;'
}
if you're using simple_html_dom, why are you doing all these superfluous things? It already wraps the resource in everything you need -- http://simplehtmldom.sourceforge.net/manual.htm
include('simple_html_dom.php');
// set up:
$html = new simple_html_dom();
// load from URL:
$html->load_file('http://www.reddit.com/r/funny');
// find those <a> elements:
$links = $html->find('a[class=thumbnail]');
// done.
echo $links;
Tested it and made some changes - this works perfect too.
<?php
// load the url and set up an array for the links
$dom = new DOMDocument();
#$dom->loadHTMLFile('http://www.reddit.com/r/funny');
$links = array();
// loop thru all the A elements found
foreach($dom->getElementsByTagName('a') as $link) {
$url = $link->getAttribute('href');
$class = $link->getAttribute('class');
// Check if the URL is not empty and if the class contains thumbnail
if(!empty($url) && strpos($class,'thumbnail') !== false) {
array_push($links, $url);
}
}
// Print results
print_r($links);
?>
This question seems to have been answered numerous times but i still cant seem to put the pieces together.
I would like to get node value of every class by name. for example
<td class="thename"><strong>32</strong></td>
<td class="thename"><strong>12</strong></td>
i would like to grab the 32 and the 12. I assume this requires for sort of for loop but not sure exactly how to go about implementing it. Here's what i have so far
$domain = "http://domain.com";
$dom = new DOMDocument();
$dom->loadHTMLFile($domain);
$xpath = new DomXpath($dom);
$div = $xpath->query('//*[#class="thename"]')->item(0);
$stuff = $div ->textContent;
echo($stuff);
Is this what your are looking for?
$result = array();
$doc = <<< HTML
<html>
<body>
<div>1
<span>2</span>
</div>
<div>3</div>
<div>4
<span class="class1"><strong>5</strong></span>
<span class="class1"><strong>6</strong></span>
<span>7</span>
</div>
</body>
</html>
HTML;
$classname = "class1";
$domdocument = new DOMDocument();
$domdocument->loadHTML($doc);
$a = new DOMXPath($domdocument);
$spans = $a->query("//*[contains(concat(' ', normalize-space(#class), ' '), ' $classname ')]");
for ($i = $spans->length - 1; $i > -1; $i--) {
$result[] = $spans->item($i)->firstChild->nodeValue;
}
echo "<pre>";
print_r($result);
exit();
i simply did this in php
$dom = new DOMDocument('1.0');
$classname = "product-name";
#$dom->loadHTMLFile("http://shophive.com/".$query);
$nodes = array();
$nodes = $dom->getElementsByTagName("div");
foreach ($nodes as $element)
{
$classy = $element->getAttribute("class");
if (strpos($classy, "product") !== false)
{
echo $classy;
echo '<br>';
}
}
I'm trying to edit html tags with DOMDocument::loadHTML in php. The html data is a part of html and not the whole page. I followed what this page (PHP - DOMDocument - need to change/replace an existing HTML tag w/ a new one) says.
This should convert pre tags into div tags but it gives "Fatal error: Uncaught exception 'DOMException' with message 'Not Found Error'."
<?php
$contents = <<<STR
<pre>hi</pre>
<pre>hello</pre>
<pre>bye</pre>
STR;
$dom = new DOMDocument;
#$dom->loadHTML($contents);
foreach( $dom->getElementsByTagName("pre") as $nodePre ) {
$nodeDiv = $dom->createElement("div", $nodePre->nodeValue);
$dom->replaceChild($nodeDiv, $nodePre);
}
echo $dom->saveHTML();
?>
[Edit]
While I'm trying to iterate the node object backwards, I get this error, 'Notice: Trying to get property of non-object...'
<?php
$contents = <<<STR
<pre>hi</pre>
<pre>hello</pre>
<pre>bye</pre>
STR;
$dom = new DOMDocument;
#$dom->loadHTML($contents);
$domPre = $dom->getElementsByTagName('pre');
$length = $domPre->length;
For ($i = $length; $i > -1 ; $i--) {
$nodePre = $domPre->item($i);
echo $nodePre->nodeValue . '<br />';
// $nodeDiv = $dom->createElement("div", $nodePre->nodeValue);
// $dom->replaceChild($nodeDiv, $nodePre);
}
// echo $dom->saveHTML();
?>
[Edit]
Okey, solved. Since the answered code has some error I post the solution here. Thanks all.
Solution:
<?php
$contents = <<<STR
<pre>hi</pre>
<pre>hello</pre>
<pre>bye</pre>
STR;
$dom = new DOMDocument;
#$dom->loadHTML($contents);
$domPre = $dom->getElementsByTagName('pre');
$length = $domPre->length;
For ($i = $length - 1; $i > -1 ; $i--) {
$nodePre = $domPre->item($i);
$nodeDiv = $dom->createElement("div", $nodePre->nodeValue);
$nodePre->parentNode->replaceChild($nodeDiv, $nodePre);
}
echo $dom->saveHTML();
?>
The problem is the call to replaceChild(). Rather than
$dom->replaceChild($nodeDiv, $nodePre);
use
$nodePre->parentNode->replaceChild($nodeDiv, $nodePre);
update
Here is a working code. Seems there is some issue with replacing multiple nodes (more info here: http://php.net/manual/en/domnode.replacechild.php) so you'll have to use a regressive loop to replace the elements.
$contents = <<<STR
<pre>hi</pre>
<pre>hello</pre>
<pre>bye</pre>
STR;
$dom = new DOMDocument;
#$dom->loadHTML($contents);
$elements = $dom->getElementsByTagName("pre");
for ($i = $elements->length - 1; $i >= 0; $i --) {
$nodePre = $elements->item($i);
$nodeDiv = $dom->createElement("div", $nodePre->nodeValue);
$nodePre->parentNode->replaceChild($nodeDiv, $nodePre);
}
Another way with paquettg/php-html-parser (didn't find the way to change name, so had to use hack with re-binding $this):
use PHPHtmlParser\Dom;
use PHPHtmlParser\Dom\HtmlNode;
$dom = new Dom;
$dom->load($text);
/** #var HtmlNode[] $tags */
foreach($dom->find('pre') as $tag) {
$changeTag = function() {
$this->name = 'div';
};
$changeTag->call($tag->tag);
};
echo (string)$dom;
