MySQL 更新查询以从所有“描述”字段中删除特定的 Html 标记

Question

我有一个 Magento 网站，其中每个产品的描述字段中都有一个锚标记，例如 <a href="link">Content</a>。

现在我想删除这个锚标签以及它在标签内的内容，但保持其余描述不变。

现在的示例描述如下：

<ul>
    <li>Cylinder head has been assembled to OEM specifications with using all new components like Cam shaft, valves and/or springs, buckets, shims etc. where applicable.</li>
    <li>
        <a href="http://sampledomain.com/media/wysiwyg/folder/file.pdf">All heads we supply pass through 24 points of quality check program.</a>
    </li>
    <li>Warranty: 1 year or 20,000 Kms factory warranty.</li>
    <li>
        <b>Kit Includes:</b>
    </li>
    <li>Fully assembled cylinder head</li>
    <li>VRS (Vehicle regrind set)</li>
    <li>Head gaskets (thickest grade)</li>
    <li>Head bolts</li>
    <li>Warranty card</li>
</ul>

现在我希望它显示如下：

<ul>
    <li>Cylinder head has been assembled to OEM specifications with using all new components like Cam shaft, valves and/or springs, buckets, shims etc. where applicable.</li>
    <li>
    </li>
    <li>Warranty: 1 year or 20,000 Kms factory warranty.</li>
    <li>
        <b>Kit Includes:</b>
    </li>
    <li>Fully assembled cylinder head</li>
    <li>VRS (Vehicle regrind set)</li>
    <li>Head gaskets (thickest grade)</li>
    <li>Head bolts</li>
    <li>Warranty card</li>
</ul>

如何使用更新查询来做到这一点？

这将完成工作..！

UPDATE your_table_name  
set description = 
concat
(
substring_index(description, '<a',1), 
substring_index(description, '</a>',-1)
);
