I do have html file this is just a prt of it though...
<div id="result" >
<div class="res_item" id="1" h="63c2c439b62a096eb3387f88465d36d0">
<div class="res_main">
<h2 class="res_main_top">
<img
src="/ff/gigablast.com.png"
alt="favicon for gigablast.com"
width=16
height=16

<h2 class="res_main_top">

Ask.com - What's Your Question?
</a>....
I want extract only url address (for example: http://www.gigablast.com and http://ask.com/ - there are atleast 10 urls in that html) from above using PHP Dom Document..I know up to this but dont know how to move ahead??
$doc = new DomDocument;
$doc->loadHTMLFile('urllist.html');
$data = $doc->getElementById('result');
then what?? this is inside tag hence I cant use $data->getElementsByTagName() here!!
Using XPath to narrow down the field to a elements inside the <div class="res_main"> element:
$doc = new DomDocument();
$doc->loadHTMLFile('urllist.html');
$xpath = new DomXpath($doc);
$query = '//div[#class="res_main"]//a';
$nodes = $xpath->query($query);
$urls = array();
foreach ($nodes as $node) {
$href = $node->getAttribute('href');
if (!empty($href)) {
$urls[] = $href;
}
}
This solves the problem of picking up all the <a> elements inside of the document, since it allows you to filter only the ones you want (since you don't care about navigation links, etc)...
You can call getElementsByTagName on a DOMElement object:
$doc = new DomDocument;
$doc->loadHTMLFile('urllist.html');
$result = $doc->getElementById('result');
$anchors = $result->getElementsByTagName('a');
$urls = array();
foreach ($anchors as $a) {
$urls[] = $a->getAttribute('href');
}
If you want to get image sources as well, that would be easy to add.
If you are just trying to extract the href attribute of all a tags in the document (and the <div id="result"> doesn't matter, you could use this:
$doc = new DomDocument;
$doc->loadHTMLFile('urllist.html');
$anchors = $doc->getElementsByTagName('a');
$urls = array();
foreach($anchors as $anchor) {
$urls[] = $anchor->attributes->href;
}
// $urls is your collection of urls in the original document.

I have this in my php file.
<?php
$str = '<div>
<p>Text</p>
I need this text...
<p>next p</p>
... and this
</div>
';
$dom=new DomDocument();
$dom->loadHTML($str);
$p = $dom->getElementsByTagName('p');
foreach ($p as $item) {
echo $item->nodeValue;
}
This gives me the correct text for the p tags, but I also need the the text between the p tags ("I need this text...", "...and this").
Anyone know how to get the text after the p tag?

Use DOMXPath:
$xpath = new DOMXpath($domDocument);
foreach ($xpath->query('//div/text()') as $textNode) {
echo $textNode->nodeValue;
}
good day Sir/Maam.
I have a certain html attribute that I want to search from the external website
I want to get the a href value but the problem is the id or class or name is random.
<div class="static">
Dynamic
</div>
This code should display all the hrefs in http://example.com
In this case I use DOMDocument and XPath to select the elements you want to access because it's very flexible and easy to use.
<?php
$html = file_get_contents("http://example.com");
$doc = new DOMDocument();
$doc->loadHTML($html);
$xpath = new DomXPath($doc);
$nodeList = $xpath->query("//a/#href");
print_r($nodeList);
// To access the values inside nodes
foreach($nodeList as $node){
echo "<p>" . $node->nodeValue . "</p>";
}
use jquery to get the value as follow:
var link = $(".static>a").attr("href");
You can use PHP DOMDocument:
<?php
$exampleurl = "http://YourDomain.com"; //set your url
$filterClass = "dynamicclass";
$dom = new DOMDocument('1.0');
#$dom->loadHTMLFile($exampleurl);
$anchors = $dom->getElementsByTagName('a');
foreach ($anchors as $element) {
$href = $element->getAttribute('href'); // all href
$class = $element->getAttribute('class');
if($class==$filterClass){
echo $href;
}
}
?>
I've been writing a php code to get information from a site, so far i was able to get the href attribute, but i cant find a way to get the text from the child node "span", can someone help me?
html- >
<a class="js-publication" href="publication/247931167">
<span class="publication-title">An approach for textual authoring</span>
</a>
This is how i am currently able to get the href ->
#$dom->loadHTMLFile($curPage);
$anchors = $dom->getElementsByTagName('a');
foreach ($anchors as $element) {
$class_ = $element->getAttribute('class');
if (0 !== strpos($class_, 'js-publication')) {
$href = $element->getAttribute('href');
if(0 === stripos($href,'publication/')){
echo $href;//link para a publicação;
echo "\n";
}
}
}
You can use DOMXpath
$html = <<< LOL
<a class="js-publication" href="publication/247931167">
<span class="publication-title">An approach for textual authoring</span>
</a>
LOL;
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXpath($dom);
foreach ($xpath->query("//a[#class='js-publication']") as $element){
echo $element->getAttribute('href');
echo $element->textContent;
}
//publication/247931167
//An approach for textual authoring
Or without the for loop, if you just want one element :
echo $xpath->query("//a[#class='js-publication']/span")[0]->textContent;
echo $xpath->query("//a[#class='js-publication']")[0]->getAttribute('href');
Ideone Demo
$content = preg_replace("~(<a href=\"(.*)\">\w+)~iU", '', $content);
$ok = preg_replace("~(</a>)~iU", '', $content);
echo $ok;
I need to control the $content...
I want to remove all link in the $content....
even <img xxxx> all to remove A tag Just save <img xxx>...
How can I do?
I need edit the REGEX??
why I just can del the first one
You can replace the anchors with their contents using DOMDocument:
$html = <<<'EOS'
<img src="http://example.com">
<img src="http://example.com">
EOS;
$doc = new DOMDocument;
$doc->loadHTML($html);
$xpath = new DOMXPath($doc);
foreach ($xpath->query('//a') as $anchor) {
$fragment = $doc->createDocumentFragment();
// collecting the child nodes
foreach ($anchor->childNodes as $node) {
$fragment->appendChild($node);
}
// replace anchor with all child nodes
$anchor->parentNode->replaceChild($fragment, $anchor);
}
echo $doc->saveHTML();
I'm pretty new to the DOMDocument class and can't seem to find an answer for what i'm trying to do.
I have a large html file and i want to grab the link from an element based on the anchor text.
so for example
$html = <<<HTML
<div class="main">
<img src="http://images.com/spacer.gif"/>Keyword</font></span>
other text
</div>
HTML;
// domdocument
$doc = new DOMDocument();
$doc->loadHTML($html);
i want to get the value of the href attribute of any element that has the text keyword. Hope that was clear
$html = <<<HTML
<div class="main">
<img src="http://images.com/spacer.gif"/>Keyword</font></span>
other text
</div>
HTML;
$keyword = "Keyword";
// domdocument
$doc = new DOMDocument();
$doc->loadHTML($html);
$as = $doc->getElementsByTagName('a');
foreach ($as as $a) {
if ($a->nodeValue === $keyword) {
echo $a->getAttribute('href'); // prints "http://link.com"
break;
}
}
