php - RSS 提要在某些项目中不显示 g: 部分

Question

我正在使用此代码来呈现我的 rss ：

$xml = new SimpleXMLExtended("<?xml version=\"1.0\" encoding=\"utf-8\"?>
            <rss xmlns:g='http://base.google.com/ns/1.0' version='2.0'></rss>");
        $channel = $xml->addChild("channel");
        $channel->addChild("title", "Kidso");
        $channel->addChild("link", "https://kidso.ro");
        $channel->addChild("description", "Kidso");
        foreach ($res as $record) {
            $gtin = $this->db->select('ean13')->where('id_product', $record['pid'])->get('bebs_product')->row();
            $item = $xml->addChild("item");
            $item->addChild("g:id", $record['pid']);
            //$item->addChild("id", $record['pid']);
            $title_feild = "g:title";
            $item->$title_feild = NULL;
            $item->$title_feild->addCData($record['name']);
            $desc_feild = "g:description";
            $item->$desc_feild = NULL;
            $item->$desc_feild->addCData($record['description']);
            $item->addChild("g:link", $record['url']);
            $item->addChild("g:image_link", $record['main_image']);
            $item->addChild("g:availability", $record['qty'] > 0 ? "in stock" : "out of stock");
            $item->addChild("g:sale_price", $record['product_price']);
            $item->addChild("g:gtin", ($gtin ? $gtin->ean13 : ""));
            $brand_feild = "g:brand";
            $item->$brand_feild = NULL;
            $item->$brand_feild->addCData($record['brand_name']);
        }

我用于 CDATA 部分的类：

<?php

class SimpleXMLExtended extends SimpleXMLElement {
    public function addCData($cdata_text) {
        $node = dom_import_simplexml($this);
        $no   = $node->ownerDocument;
        $node->appendChild($no->createCDATASection($cdata_text));
    }
}

现在 CDATA 项目在开头显示正确，g:但在其他项目中，g:从名称中转义。结果是：

<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0">
<channel>
<title>Kidso</title>
<link>https://kidso.ro</link>
<description>Kidso</description>
</channel>
<item>
<id>9645</id>
<g:title>

如何防止这种逃逸？我需要所有字段都带有g:前缀。
