The following example shows how to find descendants with a specific element name. Sort the items of the list in place (the arguments can be used for sort customization, see sorted() for their explanation). The following block of code shows how to create a named list in R. Example: Find descendants with a specific element name As other R data structures, you can name your list element objects in order to identify or having an easier access to the elements. You could write code to iterate through all of the descendants, but it's easier to use the Descendants axis. Sometimes you want to find all descendants with a specific name.
