I found this thread:How to write CDATA using SimpleXmlElement?
So I created a XML feed by following it.
For example it returns me this:
<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0"><channel><title><![CDATA[ Site title ]]></title><link>https://www.example.com</link><description><![CDATA[ Site description ]]></description><item><id>ABCD</id><title><![CDATA[ Productname ]]></title><description><![CDATA[ Product description ]]></description><gtin><![CDATA[ ]]></gtin><mpn><![CDATA[ 3305 ]]></mpn></item></channel></rss>How can I manage to make for example <gtin> and <mpn> to:
<g:gtin> and <g:mpn>
This is my php code:
<?phpclass SimpleXMLExtended extends SimpleXMLElement { public function addCData($cdata_text) { $node = dom_import_simplexml($this); $no = $node->ownerDocument; $node->appendChild($no->createCDATASection($cdata_text)); } }$xmlFile = 'feed_nl.xml';$xml = new SimpleXMLExtended('<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0"/>');$channel = $xml->addChild('channel');$channel->title = NULL;$channel->title->addCData('Site title');$channel->addChild('link', "https://www.example.com/");$channel->description = NULL;$channel->description->addCData('Site description');$query = new WP_Query( array('post_type' => 'product','post_status' => 'publish','posts_per_page' => -1,'suppress_filters' => false) );while ( $query->have_posts() ) : $query->the_post(); $post_id = get_the_ID(); $product = wc_get_product( $post_id ); $product_title = get_the_title(); $product_description = get_the_excerpt(); $mpn = $product->get_sku(); $gtin = get_field('barcode'); $item->title = NULL; $item->title->addCData($product_title); $item->description = NULL; $item->description->addCData($product_description); $item->gtin = NULL; $item->gtin->addCData($gtin); $item->mpn = NULL; $item->mpn->addCData($mpn);endwhile;$xml->saveXML($xmlFile);?>FINAL CODE:
<?phpclass SimpleXMLElementExtended extends SimpleXMLElement{ public function addChildWithCDATA($name , $value, $google) { if ($google) { $new = parent::addChild($name, '', $google); } else { $new = parent::addChild($name); } $base = dom_import_simplexml($new); $docOwner = $base->ownerDocument; $base->appendChild($docOwner->createCDATASection($value)); }}$GOOGLE_BASE_NS = 'http://base.google.com/ns/1.0';$xmlFile = 'feed_test.xml';// instead of $xml = new SimpleXMLElement('<site/>');$xml = new SimpleXMLElementExtended('<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0"/>');$channel = $xml->addChild('channel');$channel->addChildWithCDATA('title', 'Site title', '');$channel->addChild('link', "https://www.example.com");$query = new WP_Query( array('post_type' => 'product','post_status' => 'publish','posts_per_page' => 1,'suppress_filters' => false) );while ( $query->have_posts() ) : $query->the_post(); $post_id = get_the_ID(); $product = wc_get_product( $post_id ); $product_title = get_the_title(); $product_description = get_the_excerpt(); $product_link = get_the_permalink(); $product_link = $product_link .
