bgalland ,
If you post your kmz file (or part of it), I will convert part of it and show you the process for doing so.
The basic premise is to have Google Earth to import the file. Then once it is in your My Places, save it as a .kml file, not .kmz. If you do this, you can "Open with..." Wordpad (or similar text editor). Once it is open conduct a find and replace. See example..
Code:
<kml>
.
.
.
<description><!CDATA[
Info = ####
Info = ####
_P = ^P
Info = ####
Info = ####
_P = ^P
Latitdue =
Longitude =
.
.
.
]]>
</description>
.
.
.
Find "_P = ^P" and Replace with "<br/>"
If your code is missing the "<!CDATA[ . . . ]]>" portion of your <description> tag, you can add it to all your placemarks by doing a similar type "Find and Replace"
Hope this helps,
