Php dom get all attributes

Document Object Model

// same as pq(‘anything’)->htmlOuter()
// but on document root (returns doctype etc)
print phpQuery :: getDocument ();
?>

It uses DOM extension and XPath so it works only in PHP5.

If you want to use DOMDocument in your PHPUnit Tests drive on Symfony Controller (testing form)! Use like :

use Symfony\Bundle\FrameworkBundle\Test\WebTestCase;
use YourBundle\Controller\TextController;

class DefaultControllerTest extends WebTestCase
public function testIndex()
$client = static::createClient(array(), array());

$crawler = $client->request(‘GET’, ‘/text/add’);
$this->assertTrue($crawler->filter(«form»)->count() > 0, «Text form exist !»);

$domDocument = new \DOMDocument;

$domInput = $domDocument->createElement(‘input’);
$dom = $domDocument->appendChild($domInput);
$dom->setAttribute(‘slug’, ‘bloc’);

$formInput = new \Symfony\Component\DomCrawler\Field\InputFormField($domInput);
$form->set($formInput);

if ($client->getResponse()->isRedirect())
$crawler = $client->followRedirect(false);
>

// $this->assertTrue($client->getResponse()->isSuccessful());
//$this->assertEquals(200, $client->getResponse()->getStatusCode(),
// «Unexpected HTTP status code for GET /backoffice/login»);

When I tried to parse my XHTML Strict files with DOM extension, it couldn’t understand xhtml entities (like ©). I found post about it here (14-Jul-2005 09:05) which adviced to add resolveExternals = true, but it was very slow. There was some small note about xml catalogs but without any glue. Here it is:

XML catalogs is something like cache. Download all needed dtd’s to /etc/xml, edit file /etc/xml/catalog and add this line:

I hate DOM model !
so I wrote dom2array simple function (simple for use):

function dom2array($node) $res = array();
print $node->nodeType.’
‘;
if($node->nodeType == XML_TEXT_NODE) $res = $node->nodeValue;
>
else if($node->hasAttributes()) $attributes = $node->attributes;
if(!is_null($attributes)) $res[‘@attributes’] = array();
foreach ($attributes as $index=>$attr) $res[‘@attributes’][$attr->name] = $attr->value;
>
>
>
if($node->hasChildNodes()) $children = $node->childNodes;
for($i=0;$ilength;$i++) $child = $children->item($i);
$res[$child->nodeName] = dom2array($child);
>
>
>
return $res;
>

The project I’m currently working on uses XPaths to dynamically navigate through chunks of an XML file. I couldn’t find any PHP code on the net that would build the XPath to a node for me, so I wrote my own function. Turns out it wasn’t as hard as I thought it might be (yay recursion), though it does entail using some PHP shenanigans.

Hopefully it’ll save someone else the trouble of reinventing this wheel.

function getNodeXPath ( $node ) // REMEMBER THAT XPATHS USE BASE-1 INSTEAD OF BASE-0.

// Get the index for the current node by looping through the siblings.
$parentNode = $node -> parentNode ;
if( $parentNode != null ) $nodeIndex = 0 ;
do $testNode = $parentNode -> childNodes -> item ( $nodeIndex );
$nodeName = $testNode -> nodeName ;
$nodeIndex ++;

// PHP trickery! Here we create a counter based on the node
// name of the test node to use in the XPath.
if( !isset( $ $nodeName ) ) $ $nodeName = 1 ;
else $ $nodeName ++;

// Failsafe return value.
if( $nodeIndex > $parentNode -> childNodes -> length ) return( «/» );
> while( ! $node -> isSameNode ( $testNode ) );

// Recursively get the XPath for the parent.
return( getNodeXPath ( $parentNode ) . «/ < $node ->nodeName > [ ]» );
> else // Hit the root node! Note that the slash is added when
// building the XPath, so we return just an empty string.
return( «» );
>
>
?>

If you want to print the DOM XML file content, you can use the next code:

$doc = new DOMDocument();
$doc->load($xmlFileName);
echo «
» . $doc->documentURI;
$x = $doc->documentElement;
getNodeContent($x->childNodes, 0);

function getNodeContent($nodes, $level) foreach ($nodes AS $item) // print «

TIPO: » . $item->nodeType ;
printValues($item, $level);
if ($item->nodeType == 1) < //DOMElement
foreach ($item->attributes AS $itemAtt) printValues($itemAtt, $level+3);
>
if($item->childNodes || $item->childNodes->lenth > 0) getNodeContent($item->childNodes, $level+5);
>
>
>
>

function printValues($item, $level) if ($item->nodeType == 1) < //DOMElement
printLevel($level);
print $item->nodeName . »
«;
if ($level == 0) print «
«;
>
for($i=0; $i < $level; $i++) print "-";
>
>

As of PHP 5.1, libxml options may be set using constants rather than the use of proprietary DomDocument properties.

DomDocument->resolveExternals is equivilant to setting
LIBXML_DTDLOAD
LIBXML_DTDATTR

DomDocument->validateOnParse is equivilant to setting
LIBXML_DTDLOAD
LIBXML_DTDVALID

PHP 5.1 users are encouraged to use the new constants.

php dom get all attributes of a node

is there any easy way of getting all attributes of a node without checking if it has that attribute? short, here’s an example of what i’m trying to do: i have this short domdocument:

some text
 some link Copy code

okay.. now if i check p tag with getAttribute(‘align’) i’ll get the center value.. that’s cool, but i want to see if p tag has also another attribute like style without checking for every attribute possible. on img tag i’ll have to check for src, width, height, style, onclick, etc.. to verify if they exists.. but i’m thinking it might be a easier way of seeing all attributes.

Answer

Solution:

Considering you have your node as a DOMElement or DOMNode , you can use the $attributes property of the class : it contains a list of the attributes that the node has.

Using that property, you can loop over the attributes, getting the name and value of each one, with their $nodeName and $nodeValue properties.

For instance, in your case, you could use something like this :

$str = some text
 some link STR; $dom = new DOMDocument(); $dom->loadHTML($str); $p = $dom->getElementsByTagName('p')->item(0); if ($p->hasAttributes()) < foreach ($p->attributes as $attr) < $name = $attr->nodeName; $value = $attr->nodeValue; echo "Attribute '$name' :: '$value'
"; > > Copy code

Which would get you this kind of output :

Attribute 'align' :: 'center' Attribute 'style' :: 'font-size: 12px;' Copy code

i.e. we have the two attributes of the node, without knowing their names before ; and for each attribute, we can obtain its name and its value.

Answer

Solution:

Use this code, it will give you the specified attributes.

  function test()  
This is for testing php dom get all attributes of a node
   Copy code

Now when you click the conent of the p tag . It will show you align attirbute values.
