I'm trying to parse HTML using CURL DOMDocument or Xpath, but the CURLOPT_RETURNTRANSFER always returns the url's HTML in string which makes it invalid HTML to be parsed
Returned output:
string(102736) "<!DOCTYPE html>
<html itemscope itemtype="http://schema.org/QAPage" class="html__responsive">
<head>
<title>html - PHP outputting text WITHOUT echo/print? - Stack Overflow</title>
<link rel="shortcut icon" href="https://cdn.sstatic.net/Sites/stackoverflow/img/favicon.ico?v=4f32ecc8f43d">

<meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0, minimum-scale=1.0">"
PHP snipe see the output
$cc = $http->get($url);
var_dump($cc);
CURL library used: https://github.com/seikan/HTTP/blob/master/class.HTTP.php
When I remove CURLOPT_RETURNTRANSFER I see the HTML without the string(102736), but it echo the url even if i didn't request (reference: curl_exec printing results when I don't want to)
Here is the PHP snipe I used to parse html:
$cc = $http->get($url);
$doc = new \DOMDocument();
$doc->loadHTML($cc);
// all links in document
$links = [];
$arr = $doc->getElementsByTagName("a"); // DOMNodeList Object
foreach($arr as $item) { // DOMElement Object
$href = $item->getAttribute("href");
$text = trim(preg_replace("/[\r\n]+/", " ", $item->nodeValue));
$links[] = [
'href' => $href,
'text' => $text
];
}
Any idea?
Check the return value -
print_r($cc);
you will probably find that the output is an array (if the code ran successfully). From the library source, the return of get() is...
return [
'header' => $headers,
'body' => substr($response, $size),
];
So you will need to change the load line to be...
$doc->loadHTML($cc['body']);
Update:
as an example of the above and using this question as the page to work with...
$cc = $http->get("https://stackoverflow.com/questions/51319473/curlopt-returntransfer-returns-html-in-string/51319585?noredirect=1#comment89619183_51319585");
$doc = new \DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($cc['body']);
// all links in document
$links = [];
$arr = $doc->getElementsByTagName("a"); // DOMNodeList Object
foreach($arr as $item) { // DOMElement Object
$href = $item->getAttribute("href");
$text = trim(preg_replace("/[\r\n]+/", " ", $item->nodeValue));
$links[] = [
'href' => $href,
'text' => $text
];
}
print_r($links);
Outputs...

I need to read three lines of a remote page using PHP. I'm using code from Jose Vega found here to read the title:
<?php
function get_title($url){
$str = file_get_contents($url);
if(strlen($str)>0){
$str = trim(preg_replace('/\s+/', ' ', $str)); // supports line breaks inside <title>
preg_match("/\<title\>(.*)\<\/title\>/i",$str,$title); // ignore case
return $title[1];
}
}
//Example:
echo get_title("http://www.washingtontimes.com/");
?>
When I plug in a URL, I want to extract the following information:
<title>TITLE HERE</title>
<meta property="end_date" content="Tue Aug 28 2018 03:59:59 GMT+0000 (UTC)" />
<meta property="start_date" content="Mon Aug 06 2018 04:00:00 GMT+0000 (UTC)" />
Outputs: $title, $start, $end
Displayed as a title with a link to URL, followed by Starts: ____, Ends: ____, preferably converted to simple dates
Bonus Question: How can I efficiently parse dozens of sites using this script? The sites are all ascending numerically. index.php?id=103 index.php?id=104 index.php?id=105
Displaying:
ID Title Start End
#103 TitleWithLink StartDate EndDate
#104 TitleWithLink StartDate EndDate
#105 TitleWithLink StartDate EndDate
Based on your question i guessed you want to read metadata.A part of the code i will suggest now has been taken from http://php.net/manual/en/function.get-meta-tags.php
.It works fine for this SO page so it will work fine for yours too.Of course you will need to adapt it a little to get your task done.
function getUrlData($url, $raw=false) // $raw - enable for raw display
{
$result = false;
$contents = getUrlContents($url);
if (isset($contents) && is_string($contents))
{
$title = null;
$metaTags = null;
$metaProperties = null;
preg_match('/<title>([^>]*)<\/title>/si', $contents, $match );
if (isset($match) && is_array($match) && count($match) > 0)
{
$title = strip_tags($match[1]);
}
preg_match_all('/<[\s]*meta[\s]*(name|property)="?' . '([^>"]*)"?[\s]*' . 'content="?([^>"]*)"?[\s]*[\/]?[\s]*>/si', $contents, $match);
if (isset($match) && is_array($match) && count($match) == 4)
{
$originals = $match[0];
$names = $match[2];
$values = $match[3];
if (count($originals) == count($names) && count($names) == count($values))
{
$metaTags = array();
$metaProperties = $metaTags;
if ($raw) {
if (version_compare(PHP_VERSION, '5.4.0') == -1)
$flags = ENT_COMPAT;
else
$flags = ENT_COMPAT | ENT_HTML401;
}
for ($i=0, $limiti=count($names); $i < $limiti; $i++)
{
if ($match[1][$i] == 'name')
$meta_type = 'metaTags';
else
$meta_type = 'metaProperties';
if ($raw)
${$meta_type}[$names[$i]] = array (
'html' => htmlentities($originals[$i], $flags, 'UTF-8'),
'value' => $values[$i]
);
else
${$meta_type}[$names[$i]] = array (
'html' => $originals[$i],
'value' => $values[$i]
);
}
}
}
$result = array (
'title' => $title,
'metaTags' => $metaTags,
'metaProperties' => $metaProperties,
);
}
return $result;
}
function getUrlContents($url, $maximumRedirections = null, $currentRedirection = 0)
{
$result = false;
$contents = #file_get_contents($url);
// Check if we need to go somewhere else
if (isset($contents) && is_string($contents))
{
preg_match_all('/<[\s]*meta[\s]*http-equiv="?REFRESH"?' . '[\s]*content="?[0-9]*;[\s]*URL[\s]*=[\s]*([^>"]*)"?' . '[\s]*[\/]?[\s]*>/si', $contents, $match);
if (isset($match) && is_array($match) && count($match) == 2 && count($match[1]) == 1)
{
if (!isset($maximumRedirections) || $currentRedirection < $maximumRedirections)
{
return getUrlContents($match[1][0], $maximumRedirections, ++$currentRedirection);
}
$result = false;
}
else
{
$result = $contents;
}
}
return $contents;
}
$result = getUrlData('https://stackoverflow.com/questions/51939042/php-read-three-lines-of-remote-html', true);
the output of print_r($result); is:

Then to actually use it to achieve your purpose:
How can I efficiently parse dozens of sites using this script? The
sites are all ascending numerically. index.php?id=103 index.php?id=104
index.php?id=105
you need to :
-first create an array containing your urls
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<h2>HTML Table</h2>
<table>
<tr>
<th >Id</th>
<th >Title</th>
<th >start_date</th>
<th>end_date</th>
</tr>
<?php
$urls=array(103=>'index.php?id=103',104=> 'index.php?id=104', 105=>'index.php?id=105');
-then loop through this array :
foreach($urls as $id=>$url):
-each iteration you use the function getUrlData() as shown:
$result=getUrlData($url, true);
-then you retrieve the needed information using eg:
?><tr>
<td><?php echo $id; ?></td>
<td><?php echo $result['title']; ?></td>
<td><?php echo $result['metaProperties']['start_date']['value']; ?></td>
<td><?php echo $result['metaProperties']['end_date']['value']; ?></td>
</tr>
to build each line and row.
At the end of the process you would have get your expected table:
Endforeach;?>
</table></body>
</html>
Well, you could solve your issue with the DomDocument class.
$doc = new \DomDocument();
$title = $start = $end = '';
if ($doc->loadHTMLFile($url)) {
// Get the title
$titles = $dom->getElementsByTagName('title');
if ($titles->length > 0) {
$title = $titles->item(0)->nodeValue;
}
// get meta elements
$xpath = new \DOMXPath($doc);
$ends = $xpath->query('//meta[#property="end_date"]');
$if ($ends->length > 0) {
$end = $ends->item(0)->getAttribute('content');
}
$starts = $xpath->query('//meta[#property="start_date"]');
if ($starts->length > 0) {
$start = $starts->item(0)->getAttribute('content');
}
var_dump($title, $start, $end);
}
With the getElementsByTagName method of the DomDocument class you can find the title element in the whole html of a given url. With the DOMXPath class you can retrieve the specific meta data you want. You don 't need much code for finding specific informations in a html string.
The code shown above is not tested.
I have the below html
<p>text1</p>
<ul>
<li>list-a1</li>
<li>list-a2</li>
<li>list-a3</li>
</ul>
<p>text2</p>
<ul>
<li>list-b1</li>
<li>list-b2</li>
<li>list-b3</li>
</ul>
<p>text3</p>
Does anyone have an idea to parse this html file with php to get this output using complex array
fist one for the tags "p"
and the second for tags "ul" because after above every "p" tag a tag "ul"
Array
(
[0] => Array
(
[value] => text1
(
[il] => list-a1
[il] => list-a2
[il] => list-a3
)
)
[1] => Array
(
[value] => text2
(
[il] => list-b1
[il] => list-b2
[il] => list-b3
)
)
)
I can't use replace or removing all tags cause I use
foreach ($doc->getElementsByTagName('p') as $link)
{
$dont = $link->textContent;
if (strpos($dont, 'document.') === false) {
$links2[] = array(
'value' => $link->textContent, );
}
$er=0;
foreach ($doc->getElementsByTagName('ul') as $link)
{
$dont2 = $link->nodeValue;
//echo $dont2;
if (strpos($dont2, 'favorisContribuer') === false) {
$links3[]= array(
'il' => $link->nodeValue, );
}
You could use the DOMDocument class (http://php.net/manual/en/class.domdocument.php)
You can see an example below.
<?php
$html = '
<p>text1</p>
<ul>
<li>list-a1</li>
<li>list-a2</li>
<li>list-a3</li>
</ul>
<p>text2</p>
<ul>
<li>list-b1</li>
<li>list-b2</li>
<li>list-b3</li>
</ul>
<p>text3</p>
';
$doc = new DOMDocument();
$doc->loadHTML($html);
$textContent = $doc->textContent;
$textContent = trim(preg_replace('/\t+/', '<br>', $textContent));
echo '
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
' . $textContent . '
</body>
</html>
';
?>
However, I would suggest using javascript to find the content and send it to php instead.
I am new to using DOM with PHP and need some help figuring out a solution of iterating xpath into an array. The the examples I found online provided very little help.

This is how I approach the issue.
$__data = "xmp-cache-test.xml";
$content = file_get_contents('xmp-cache-test.xml');
if(preg_match("/(\<x\:xmpmeta.*?\>.*?\<\/x\:xmpmeta\>)/s", $content, $matches))
$data = "<?xml version='1.0'?>\n" . $matches[1];
$myXmlString = $data ;
$myXmlFilename = $__data;
$doc = new DOMDocument();
$doc->loadXML($myXmlString);
$doc->documentURI = $myXmlFilename;
$xpath = new DOMXpath($doc);
$xpath->registerNamespace('x', 'adobe:ns:meta/');
$xpath->registerNamespace('xmp', 'http://ns.adobe.com/xap/1.0/');
$xpath->registerNamespace("Iptc4xmpCore", "http://iptc.org/std/Iptc4xmpCore/1.0/xmlns/");
$xpath->registerNamespace('rdf', 'http://www.w3.org/1999/02/22-rdf-syntax-ns#');
$elements = $xpath->evaluate('//rdf:RDF/rdf:Description');
$arr_xmp = iterator_to_array($elements);
print_r($arr_xmp);
// The print result:

The above result is not what I had expected.
I would rather to have in the array for viewing something more like the following example below
and along with a few other options:

Options: By giving an example would be helpful.
How should I approach the creation of the array by using DOM?
If I need to remove say "tiff and exif" from the array what
should the approach be like?
Use Dom to update say "photoshop:Credit" value.
How to use DOM to reverse the array back to the XML string.
=============EDIT===================
The xml to array part, almost the same question here: What is the best php DOM 2 Array function?
I played with the code a bit and this is the result:
function xml_to_array($root) {
$result = array();
if ($root->hasAttributes()) {
$attrs = $root->attributes;
foreach ($attrs as $attr) {
$result['#attributes'][$attr->name] = $attr->value;
}
}
if ($root->hasChildNodes()) {
$children = $root->childNodes;
if ($children->length == 1) {
$child = $children->item(0);
if ($child->nodeType == XML_TEXT_NODE) {
$result['_value'] = $child->nodeValue;
return count($result) == 1
? $result['_value']
: $result;
}
}
$groups = array();
foreach ($children as $child) {
if($child->nodeType == XML_TEXT_NODE && empty(trim($child->nodeValue))) continue;
if (!isset($result[$child->nodeName])) {
$result[$child->nodeName] = xml_to_array($child);
} else {
if (!isset($groups[$child->nodeName])) {
$result[$child->nodeName] = array($result[$child->nodeName]);
$groups[$child->nodeName] = 1;
}
$result[$child->nodeName][] = xml_to_array($child);
}
}
}
return $result;
}
// $content = your xml raw source
if(preg_match("/(\<x\:xmpmeta.*?\>.*?\<\/x\:xmpmeta\>)/s", $content, $matches))
$data = "<?xml version='1.0'?>\n" . $matches[1];
$myXmlString = $data ;
//$myXmlFilename = $__data;
$doc = new DOMDocument();
$doc->loadXML($myXmlString);
$array = xml_to_array($doc);
print_r($array);
Very neat function someone wrote there, it iterates thru-out the xml collecting attributes and node values and pretty much ignoring the pain associated to dreadful namespaces.
If you need to remove an item from the array, just use unset, as in:
unset($array['x:xmpmeta']['rdf:RDF']['rdf:Description']['tiff:BitsPerSample']);
As for how to update an attribute value, exact same question here: Change tag attribute value with PHP DOMDocument
$dom = new DOMDocument();
$dom->loadHTML('Click here');
foreach ($dom->getElementsByTagName('a') as $item) {
$item->setAttribute('href', 'http://google.com/');
echo $dom->saveHTML();
exit;
}
And finally, how to reverse back from array to DOM: there is no easy way, you would have to manually create a DOM object and create nodes and attributes one by one.
Once populated you would call http://php.net/manual/en/domdocument.savexml.php to get the xml code.
<?php
$doc = new DOMDocument('1.0');
// we want a nice output
$doc->formatOutput = true;
$root = $doc->createElement('book');
$root = $doc->appendChild($root);
$title = $doc->createElement('title');
$title = $root->appendChild($title);
$text = $doc->createTextNode('This is the title');
$text = $title->appendChild($text);
echo "Saving all the document:\n";
echo $doc->saveXML() . "\n";
echo "Saving only the title part:\n";
echo $doc->saveXML($title);
?>
Hope this helps,
I'm trying to find all the elements of a tag in HTML and get the starting and ending point.
Here's my sample HTML
some content <iframe></iframe> <iframe></iframe> another content
Here's what I have got so far for code.
$dom = HtmlDomParser::str_get_html( $this->content );
$iframes = array();
foreach( $dom->find( 'iframe' ) as $iframe) {
$iframes[] = $iframe;
}
return array(
'hasIFrame' => count( $iframes ) > 0
);
Getting the number of elements is easy but I'm not sure if HTMLDomParser can get the starting and ending position?
What I want is
array(
'hasIFrame' => true,
'numberOfElements => 2,
array (
0 => array (
'start' => $firstStartingElement,
'end' => $firstEndingElement
),
1 => array (
'start' => $secondStartingElement,
'end' => $secondEndingElement
)
)
If you have a look at the official doc (http://simplehtmldom.sourceforge.net/) you can easily found out how many elements of a type there is in your DOM :
// Find all images
foreach($html->find('img') as $element) {
echo $element->src . '<br>';
}
All you have to do is retrieving $html->find('iframe') and verify its size to know if there is at least once
You can do something like this:
$html = "some content <iframe></iframe> <iframe></iframe> another content";
preg_match_all('/<iframe>/', $html, $iframesStartPositions, PREG_OFFSET_CAPTURE);
preg_match_all('/<iframe\/>/', $html, $iframesEndPositions, PREG_OFFSET_CAPTURE);
$iframesPositions = array();
foreach( $dom->find( 'iframe' ) as $key => $iframe) {
$iframesPositions[] = array(
'start' => $iframesStartPositions[0][$key][1],
'end' => $iframesEndPositions[0][$key][1] + 9 // 9 is the length of the ending tag <iframe/>
);
}
return array(
'hasIFrame' => count($iframesPositions) > 0,
'numberOfElements' => count($iframesPositions),
'positions' => $iframesPositions
);
I'm trying to build a 3d php array, that ultimately gets outputted as xml... This is the code I'm trying to use to prove the concept...
$test = array('apple','orange');
$results = Array(
'success' => '1',
'error_number' => '',
'error_message' => '',
'results' => Array (
'number_of_reports' => mysql_num_rows($run),
'item' => $test
)
);
I want the resulting array to look like
<success>1</success>
<error_number/>
<error_message/>
<results>
<number_of_reports>18</number_of_reports>
<item>
<0>apple</0>
<1>orange</1>
</item>
</results>
In reality the apple and orange array would be a 3d one in itself... If you've ever used the ebay api... you'll have an idea of what I'm trying to do (I think)
Try it:
Code:
<?php
$test = array('apple','orange');
$results = Array(
'success' => '1',
'error_number' => '',
'error_message' => '',
'results' => Array (
'number_of_reports' => 1,
'item' => $test
)
);
print_r($results);
function addChild1($xml, $item, $clave)
{
if(is_array($item)){
$tempNode = $xml->addChild($clave,'');
foreach ($item as $a => $b)
{
addChild1($tempNode, $b, $a);
}
} else {
$xml->addChild("$clave", "$item");
}
}
$xml = new SimpleXMLElement('<root/>');
addChild1($xml, $results,'data');
$ret = $xml->asXML();
print $ret;
Output:
<?xml version="1.0"?>
<root><data><success>1</success><error_number></error_number><error_message></error_message><results><number_of_reports>1</number_of_reports><item><0>apple</0><1>orange</1></item></results></data></root>
See below URL. I think it very use full to you:-
How to convert array to SimpleXML
Or Try it:-
$xml = new SimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML();
