Using Fusion Tables
XML is everywhere
●Microsoft Office docx, xlsx, etc. are xml documents.
●Most databases can read and write xml with the aid
of XSLT.
●Google Earth KML is XML (just change the file
extension)
●KMZ is just KML text + images that have been
compressed into one file. (change the file extension
to .zip and unzip)
Understanding XML/KML
●Text document that can be opened by any text
editor (notepad, notepad++, Word, etc.)
●Most XML is created by an application, not written
by hand.
●Text editor find and replace tools are useful to clean
up data for import or export.
●Regular Expression is a powerful search/replace
language built into many text editors.
