我想在一个 Tridion Schema 中应用一些额外的过滤 xslt。
我有一个名为“图像”的字段。它是一个 RTF，已配置为通过在编辑格式功能下选择它来允许图像和超链接。
其背后的想法是在 RTF 中插入和 Image 并使其成为 RTF 字段。
样本有效来源：
1.<a title="google site" href="http://google.com"><img style="width: 141px; height: 167px;" alt="Image" title="Image" src="tcm:202-11587"/></a>
2.<a title="Internal link" href="tcm:202-9720"><img style="width: 141px; height: 167px;" alt="Image" title="Image" src="tcm:202-11587"/></a>
由于 RTF 允许超链接和图像，因此用户可能会以不同的格式输入它们。无效的：
1.<a title="google site" href="http://google.com"></a>
<img style="width: 141px; height: 167px;" alt="Image" title="Image" src="tcm:202-11587"/>
2.<img style="width: 141px; height: 167px;" alt="Image" title="Image" src="tcm:202-11587"/>
<a title="google site" href="http://google.com"></a>
3.<a title="google site" href="http://google.com"><img style="width: 141px; height: 167px;" alt="Image" title="Image" src="tcm:202-11587"/></a>
<a title="Internal link" href="tcm:202-9720"><img style="width: 141px; height: 167px;" alt="Image" title="Image" src="tcm:202-11587"/></a>
规则：
1.Only one Image should be allowed and it should be hyperlink.
2.There should be one <img> tag wrapped by one <a> tag.
3. Multiple images are not allowed.
我知道这可以使用事件系统来完成。但我仍然想通过应用 XSLT 过滤来实现。

我想知道是否可以通过在模式源的 tcm:FilterXSLT 中编写一些 xslt 代码来做到这一点。
任何人都可以帮助如何做到这一点。
谢谢。
