To Use:

/exportguild

Prints your Guild Roster to an edit form. From there you can copy and paste it to any XML editor to work with out of game. I save mine from Dreamweaver or XML Notepad and then open it up in MS Excel so that I can sort and filter it.

It's a great tool for making sure that notes are all up to date, that everyone has an officer note or just to be able to search your officer or guild notes.

We use officer notes to indicate mains and alts, it's nice to be able to search for all toons owned by one person.

Fields Exported: Blizz Name (Guild XML Exporter Name)

Name (character)
Rank (rank)
RankIndex (ranknumber)
Level (level)
Note (guildnote)
Officernote (officernote)
achievementPoints (achievementpoints) <- individual achievement points, not guild achievements or rep.
achievementRank (achievementrank)

Notes:

If you are not in a guild, the addon does nothing. If you are in a guild but are not an officer, the addon returns the information as expected, with the Officer Notes fields empty.
<, > and & characters do bad things to XML. If they appear in your notes, they'll break your file. Creative use of a web browser and XML editor like XML Notepad will help you track down the culprits so that you can remove them from your in-game notes.
Special characters will work with the included XML header, but only if you save the file in an application that manages XML properly. A plain old text editor will save what looks like a valid XML file but Excel (or a browser) will choke on the special characters when you try to open it.
This exports a lot of data. The larger your guild is, the longer you 'll have to wait for the data to load.

Potential Future Improvements:

A config screen that allows you to select what fields should be exported. If we do that, I'll include Blizz's location and online status as well.
