Looking for an XML editor

Property List Editor in /Developer/Applications/Utilities/ is what you're looking for. Additonally, plutil is the comparable CLI tool.

Also, a google search for *"os X xml editor"* brings up other options.

Checking xml syntax? Use xmllint. It's built in. Details via Terminal.app:

man xmllint

There's an XML viewer example buried (deep) inside Xcode. Look here:

/developer/Examples/Foundation/XMLBrowser

For various xml information related to libxml2 (an XML library that's built into Mac OS X), visit here:

http://xmlsoft.org

Tools and such are listed there.

And there's a pile of NSXML stuff available via Xcode.

If I were looking to verify XML syntax (which happens fairly regularly), xmllint is one of the key tools I tend to use.

And yes, Google is your friend.

Nice find. I don't do anything with XML except WRT to plists.

Thanks for the feedback. Good computing.
