Add namespace attribute to xml node in php

Question

Following is the node I am trying to create in my XML -

<?xml version="1.0" standalone="no" ?>
<manifest identifier="com.scorm.golfsamples.contentpackaging.multioscosinglefile.20043rd"
          version="1"
          xmlns="http://www.imsglobal.org/xsd/imscp_v1p1"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns:adlcp="http://www.adlnet.org/xsd/adlcp_v1p3"
          xmlns:adlseq="http://www.adlnet.org/xsd/adlseq_v1p3"
          xmlns:adlnav="http://www.adlnet.org/xsd/adlnav_v1p3"
          xmlns:imsss="http://www.imsglobal.org/xsd/imsss"
          xsi:schemaLocation="http://www.imsglobal.org/xsd/imscp_v1p1 imscp_v1p1.xsd
                              http://www.adlnet.org/xsd/adlcp_v1p3 adlcp_v1p3.xsd
                              http://www.adlnet.org/xsd/adlseq_v1p3 adlseq_v1p3.xsd
                              http://www.adlnet.org/xsd/adlnav_v1p3 adlnav_v1p3.xsd
                              http://www.imsglobal.org/xsd/imsss imsss_v1p0.xsd">

Code is working fine for identifier and version attribute but unable to generate it with namespace like xmlns="http://www.imsglobal.org/xsd/imscp_v1p1"

Tried this code from here but unable to make it :(

$doc = new DOMDocument( '1.0' );
$doc->loadXML( $source );

// (1) We just create a "namespace'd" attribute without appending it to any element.
$attr_ns = $doc->createAttributeNS( '{namespace_uri_here}', 'example:attr' );

print $doc->saveXML() . "\n";

Codepad Link - http://codepad.org/uLJc4hpP

Full code -

   //creating an XML document
    $dom = new DOMDocument('1.0');
    $dom->xmlStandalone = false;

    //create element manifest
    $manfiestNode = $dom->createElement('manifest',"");

    //create attribute identifier
    $manfiestNodeAttr = $dom->createAttribute('identifier');

    //value for the manifest node identifier value
    $date = new DateTime();
    $manfiestNodeAttr->value = 'course_'.date_format($date,'U');

    //append attribute to the manifest element
    $manfiestNode->appendChild($manfiestNodeAttr);

    //create attribute with an associated namespace
    $nodeAttr = $manfiestNode->createAttributeNS('{namespace_uri_here}', 'example:attr');

    //append namespace to the manifest element
    $nodeAttr->appendChild($manfiestNode);

    //append manifest element to the document
    $dom->appendChild($manfiestNode);

    var_dump($dom->saveXML());

Let me know what I am conceptually doing wrong and how could I make it working.

I tried by changing $manfiestNode to $dom in line 20[codepad link] but still no luck :(.

Error-

Fatal error: Call to undefined method DOMElement::createAttributeNS() on line 20

Try with createAttribute like following

$dom = new DOMDocument('1.0','UTF-8'); 

// root manifest
$root = $dom->appendChild($dom->createElement('manifest')); 

// identifier   
$date = new DateTime();
$manfiestNodeAttr_value = 'course_'.date_format($date,'U');

$root->appendChild($dom->createAttribute('identifier'))->appendChild($dom->createTextNode($manfiestNodeAttr_value)); 

// version
$version = 1;

$root->appendChild($dom->createAttribute('version'))->appendChild($dom->createTextNode($version)); 

// xmlns:xsi
$root->appendChild($dom->createAttribute('xmlns:xsi'))->appendChild($dom->createTextNode("http://www.w3.org/2001/XMLSchema-instance"));

print_r($dom->saveXML());

my question is about generating xmlns:xsi these type of attributes, version and identifier is sucessfully created from above code

Bora Over a year ago

@swapnesh But you can create xmlns with createAttribute?

swapnesh Over a year ago

yeah i tried that way $dom->createAttribute('xmlns:xsi') and it works :) only thing is is it really a clean way of generating like this..let me know if you have some thoughts on it +1 :)

Bora Over a year ago

I do not know very well about DOMDocument. I just googled and looked aroud php.net and want to help you. Updated codes with sample xmlns:xsi create attribute like yours.

swapnesh Over a year ago

ohh issue with that...if I add for a xml output header('Content-type: application/xml'); then it is not showing the xmlns:xsi however it is showing in a string
