Up until this week, when I needed to hack an XML.Config or Sitemap file, I pulled out WordPad and went to town. After CRM complained about the file not being valid for a couple of goes I normally figured out where I’d gone wrong and all was good.
I thought there had to be a better way so I googled for xml editors and up popped XML Notepad.
It just works. If you have to mess about shuffling bits of XML around, it does the job nicely.
