Description
The functx:remove-elements-not-contents function removes descendant elements from all of the nodes in $nodes based on name, but keeps the contents of the removed elements. This is useful, for example, for removing in-line formatting. The $names argument is a sequence of strings that represent element names to remove. Prefixes can (and must) be used in the $names values for elements that are prefixed in the input documents. You can also specify wildcard values "*", "*:" and ":*" in the second argument. See the description for functx:name-test for details.
