我正在尝试将我的 Yahoo Store 目录导入 Google 购物。Yahoo 目录导出为 CSV，但它必须是 XML。我正在创建一个 PHP 脚本来进行转换。到目前为止，我已经创建了所有适当的元素，根据需要转换了名称和值，但是在运输价格元素方面遇到了问题。它在值之前自动关闭，即：

<g:price/>PRICE

代替

<g:price>PRICE</g:price>

我相当肯定它与 appendChild 或嵌套有关，但我仍在学习，这是我第一次在 PHP 中使用 CSV 或 XML。我将不胜感激在解决此问题和清理我凌乱的代码方面的任何建议或想法。

CSV 示例 (input.csv)，只有一个产品：

id,name,caption,product-url,c4-tab4-local,c4-tab5-local,condition,orderable,price,sale-price,code,label,ship-weight
"10auodgrwibl","5 PACK Magnet for Military Style Steal Ammo Can","Our Military Ammo Can Magnets will stick to any side of a standard issue military ammo can like the one pictured. Use these to mark your can(s) so you don't have to open them up to see whats inside. Great for preppers! Each magnet measures approx. 3.54"" x 2.05"" or 90 x 52 mm

我很高兴你能够解决这个问题。但总的来说，从 CSV 生成 XML 是相当困难的。Google Shopping 也接受 CSV 文件，因此您可以使用简单的 fgetcsv 和 fputcsv 重新映射 Yahoo 目录 CSV 导出文件。这是一个简短的示例，可以为您提供这个想法：

// Read lines from Yahoo CSV file
while($row = fgetcsv($fp_in))
{
  // Strip HTML from caption
  $row[2] = strip_tags($row[2]);
  // Write line to Google Shopping CSV feed file
  fputcsv($fp_out);
}

作为参考，您可以阅读此Perl 脚本中的代码来为 Yahoo Store 生成 Google 购物提要，并根据专业生成的提要验证您的输出，您可以试用这个免费的 Yahoo Store 谷歌购物提要生成器。
