A sorting operation can be performed on various types of lists and list items. The types of lists that can be sorted in Oxygen XML Editor depend on the framework (document type), but examples of the types that can be sorted include:
  • Ordered list (DITA, DocBook, XHTML, TEI)
  • Unordered list (DITA, DocBook, XHTML, TEI)
  • Definition list (DITA)
  • Variable list (DocBook)
  • Parameter list (DITA)
  • Simple list (DITA)
  • Required conditions (DITA Machinery Task)
  • Supplies list (DITA Machinery Task)
  • Spare parts list (DITA Machinery Task)
  • Safety conditions (DITA Machinery Task)

The sorting mechanism works on an entire list or on a selection of list items. To sort items in a list, select the items or list and use the Sort action from the main toolbar or the contextual menu. This opens the Sort dialog box.

Figure 1: Sorting List Items

This dialog box sets the range that is sorted and the sorting criteria. The range is automatically selected depending on whether you sort an entire list or only a selection of its items.

Note: When you invoke the sorting operation over an entire list, the Selected rows option is disabled.
The Criteria section specifies the sorting criteria, defined by the following:
  • The name of the type of item being sorted.
  • The type of the information that is sorted. You can choose between the following:
    • Text - Alphanumeric characters.
    • Numeric - Regular integer or floating point numbers are accepted.
    • Date - Default date and time formats from the local OS are accepted (such as short, medium, long, full, xs:date, and xs:dateTime).
  • The sorting direction (either ascending or descending).
After you finish configuring the options in the Sort dialog box, click OK to complete the sorting operation. If you want to revert to the initial order of your content, press Ctrl + Z (Command + Z on OS X) on your keyboard.
Note: The sorting support takes the value of the xml:lang attribute into account and sorts the content in a natural order.
