class XmlCompletionProvider extends org.fife.ui.autocomplete.DefaultCompletionProvider
A completion provider that, in the absence of a DTD or XML schema, makes a best guess at what completion choices the user might want for XML. It does this by looking at what XML element names and attributes have been used elsewhere in the document:

  • If the caret is not in an XML tag, no completion choices are suggested.
  • If the caret is in an XML tag name, other tag names in the document that start with that prefix are suggested.
  • If the caret is in an XML tag, but not in the tag's name, the document is parsed for other instances of that tag. If any are found, all attributes used for that tag elsewhere are suggested.
