the code below successfully helps me to create a div.
$dom = new DOMDocument();
$ele = $dom->createElement('div', $textcon);
$dom->appendChild($ele);
$html = $dom->saveXML();
fwrite($myfile,$html);
I am having trouble creating a child div in the code below once the primary div is created
$file = "http://dd/showcase.php";
$doc = new DOMDocument();
$doc->loadHTMLFile($file);
$element = $doc->getElementsByTagName('div');
$dom = $element;
$ele = $dom->createElement('div', $textcon);
$dom->appendChild($ele);
$html = $dom->saveXML();
fwrite($myfile,$html);
The method
getElementsByTagName('div')
returns a list of all the elements named 'div', not a single element. Hence you need to add the child div to the first element of the list returned by the above method.
$dom = $element[0];
This might solve the problem
<?php
$file = "http://dd/showcase.php";
$doc = new DOMDocument();
$doc->loadHTMLFile($file);
$ele = $doc->createElement('div', $textcon);
$element = $doc->getElementsByTagName('div')->item(0);
$element->appendChild($ele);
$ele ->setAttribute('id', $divname);
$ele ->setAttribute('style', 'background: '.$divbgcolor.'; color :'.$divfontcolor.' ;display : table-col; width :100%;');
$doc->appendChild($element);
$html = $doc->saveXML();
fwrite($myfile,$html);
?>
Try this out.
Thanks

I want to generate content with an array and place that in my Document that I loaded over a site. That is what I got so far. Is there a way for this with the foreach? Is there an append function?
$dom = new \DOMDocument();
$dom->loadHTML($data);
// create the new element
$newNode = $dom->createElement('div', 'this is new');
$newNode->setAttribute('id', 'new_div');
//foreach
$count = 0;
foreach($tags->contents as $content){
$contents[$count] = $content->text;
}
// fetch and replace the old element
$oldNode = $dom->getElementById('blog-xpath');
$oldNode->parentNode->replaceChild($newNode, $oldNode);
$nodes = $dom->saveHTML($dom->documentElement);
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);
?>
I am trying to use the dom object to simplify the implementation of a glossary tooltip. What I need to do is to replace a text element in a paragraph, but NOT in an anchor tag that may be embedded in the paragraph.
$html = '<p>Replace this tag not this tag</p>';
$document = new DOMDocument();
$document->loadHTML($html);
$document->preserveWhiteSpace = false;
$document->validateOnParse = true;
$nodes = $document->getElementByTagName("p");
foreach ($nodes as $node) {
$node->nodeValue = str_replace("tag","element",$node->nodeValue);
}
echo $document->saveHTML();
I get:
'...<p>Replace this element not this element</p>...'
I want:
'...<p>Replace this element not this tag</p>...'
How do I implement this such that only the parent node text is changed and the child node (a tag) is not changed?
Try this:
$html = '<p>Replace this tag not this tag</p>';
$document = new DOMDocument();
$document->loadHTML($html);
$document->preserveWhiteSpace = false;
$document->validateOnParse = true;
$nodes = $document->getElementsByTagName("p");
foreach ($nodes as $node) {
while( $node->hasChildNodes() ) {
$node = $node->childNodes->item(0);
}
$node->nodeValue = str_replace("tag","element",$node->nodeValue);
}
echo $document->saveHTML();
Hope this helps.
UPDATE
To answer #paul's question in the comments below, you can create
$html = '<p>Replace this tag not this tag</p>';
$document = new DOMDocument();
$document->loadHTML($html);
$document->preserveWhiteSpace = false;
$document->validateOnParse = true;
$nodes = $document->getElementsByTagName("p");
//create the element which should replace the text in the original string
$elem = $document->createElement( 'dfn', 'tag' );
$attr = $document->createAttribute('title');
$attr->value = 'element';
$elem->appendChild( $attr );
foreach ($nodes as $node) {
while( $node->hasChildNodes() ) {
$node = $node->childNodes->item(0);
}
//dump the new string here, which replaces the source string
$node->nodeValue = str_replace("tag",$document->saveHTML($elem),$node->nodeValue);
}
echo $document->saveHTML();
what i want to do is to get an element with its class name and show it as a actual html element not it nodes or its inner data
here is my code
$html = file_get_contents("www.site.com");
$dom = new DOMDocument('1.0');
$dom->loadHTML($html);
$element = $dom->getElementById('myid');
$string = $element->C14N();
here is how i do it using ID but i want to now if there is a way to do this using class apparently there is no getElementByClass method
There is no straightforward method in php dom to do this. You will have to walk all the elements and check if their class attribute contains the class name you need...
$html = file_get_contents("www.site.com");
$dom = new DOMDocument('1.0');
$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('div') as $element) {
if (strpos($element->getAttribute('class'), 'yourClassNameHere') !== false) {
$string = $element->C14N();
}
}
You can also use DOMXpath:
$xpath = new DOMXpath($doc);
foreach ($xpath->query("*/div[#class='yourClassNameHere']") as $element) {
$string = $element->C14N();
}
I'm following a simplified version of the scraping tutorial by NetTuts here, which basically finds all divs with class=preview
http://net.tutsplus.com/tutorials/php/html-parsing-and-screen-scraping-with-the-simple-html-dom-library/comment-page-1/#comments
This is my code. The problem is that when I count $items I get only 1, so it's getting only the first div with class=preview, not all of them.
$articles = array();
$html = new simple_html_dom();
$html->load_file('http://net.tutsplus.com/page/76/');
$items = $html->find('div[class=preview]');
echo "count: " . count($items);
Try using DOMDocument and DOMXPath:
$file = file_get_contents('http://net.tutsplus.com/page/76/');
$dom = new DOMDocument();
#$dom->loadHTML($file);
$domx = new DOMXPath($dom);
$nodelist = $domx->evaluate("//div[#class='preview']");
foreach ($nodelist as $node) { print $node->nodeValue; }
