从 GEarth 与 Google 地图中调试 KML 花费了太多时间。有人可以给我一个提示，说明为什么下面的“实体替换”在 GE 中可以正常工作，但在 GMaps 中却失败了。

我运行了 XMLValidate 并且文件很好，但是 [CDATA] 中的标签不会被 GoogleMaps API 替换，只有在 GEarth 中。我阅读了有关BalloonStyle 实体替换的最佳实践 KML 文档，以及OGC KML 2.2 标准中令人麻木的描述，并调整和修剪了文件，但我仍然感到困惑。在以下情况下，我无法让实体替换在 GMaps API 中工作。

有任何想法吗？-谢谢

我认为如果你使用简单的<ExtendedData>和<Data>元素来提供数据，它可能会起作用，以及或而不是<Schema>和<SchemaData>元素。

看它，你甚至需要模式数据吗？您是否在需要将数据作为类型字符串的其他应用程序中使用 KML？

谷歌地球和谷歌地图忽略了类型数据，所以如果它对你没有其他用途，它只会让你的 kml 膨胀。

您链接到的文档的前半部分涉及此问题。

回答你关于为什么这在谷歌地图中不起作用的问题：谷歌地图 API 正式不支持<Schema>两者。完全支持和部分支持（参考）。<SchemaData><Data><ExtendedData>

该参考提供了一个表格，详细说明了 API 支持的 KML 功能。以下是相关行：

+----------------+-----------------------+----------------------------+
|  KML element   | Supported in the API? |         Comment            |
+----------------+-----------------------+----------------------------+
| <BalloonStyle> | partially             | only <text> is supported   |
| <Data>         | yes                   |                            |
| <ExtendedData> | partially             | untyped <Data> only, no    |
|                |                       | <SimpleData> or <Schema>,  |
|                |                       | and entity replacements of |
|                |                       | the form $[dataName] are   |
|                |                       | not supported.             |
| <Schema>       | no                    |                            |
| <SchemaData>   | no                    |                            |
