At my last job I downloaded an xml editor that worked really well to make changes to Feature Class attribute schemas. By exporting the "schema only" in arc catalog I got the xml file and open it in the editor.
The editor would display the xml as a series of folders which makes inserting a new field a snap. I thought it was notepad ++ but I just downloaded it here at my new job and it's only displaying a traditional xml <tags> type of format.
Does anyone know which xml editor I'm describing here?
