在BalloonStyle中KML实体置换在Google地图失败，而不是谷歌地球(KML Entit

花了太多的时间从内GEarth与谷歌地图的调试KML。有人可以给我为什么下面的下面的“实体更换”工作正常GE但在GMaps失败的提示。

我跑XMLVALIDATE和文件是好的，但在[CDATA]的标签不会通过谷歌地图API所取代，只在GEarth。我读了最佳实践KML文件BalloonStyle中实体的置换，并在头脑麻木的描述OGC KML 2.2标准，并调整和修整的文件，但我仍然难住了。我不能让实体置换到GMaps API工作在下面的情况。

有任何想法吗？ -谢谢

Answer 1:

我认为，它可能会工作，如果你用简单的<ExtendedData>和<Data>元素提供的数据，以及或而非<Schema>和<SchemaData>元素。

从看它，你甚至需要架构数据？您使用的KML在需要数据作为输入字符串的一些其它应用程序？

谷歌地球和谷歌地图忽略的数据类型，所以它只是腹胀您的KML如果没有其它目的为您服务。

该文件的前半部分，你链接到这个交易。

Answer 2:

要回答你关于为什么这不会在谷歌地图工作的问题：两个<Schema>和<SchemaData>被正式由谷歌地图API不支持。 <Data>完全支持和<ExtendedData>部分支持（参考）。

参考提供一个表，详细说明由API支持的KML特征。下面是相关行：

+----------------+-----------------------+----------------------------+
|  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                    |                            |
