<?xml> node needed in created LIBKML files

[khicks]

Unless I am missing some option in the creation of LIBKML files, none of my files created have the <?xml> node at the beginning of the file. In most instances this isn't an issue, however, I've discovered that KML files without this node will not email to/from an iCloud account. iCloud must be blocking them for some reason. If I manually edit the file and put the following line in, it emails fine. Is there anyway this can be automatically done as at the moment I am having to rewrite the file myself and including the line. My files are being updated often so this is a lot of unnecessary I/O.

"<?xml version="1.0" encoding="UTF-8"?>"

Thanks,

Kathy
