雅虎商店目录到谷歌购物提要 PHP 脚本

Question

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，并根据需要转换了名称和值，但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

而不是

<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。对于解决此问题和清理我凌乱的代码的任何建议或想法，我将不胜感激。

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

很高兴您能够解决问题。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。下面是一个简短的示例，可以帮助您了解这个想法：

// 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 script to generate a Google Shopping feed for Yahoo Store 中的代码，并根据专业生成的提要验证您的输出，您可以尝试此free Google Shopping feed generator for Yahoo Stores。
