functx:remove-attributes

Removes attributes from an XML element, based on name

Description

The functx:remove-attributes function removes attributes from a sequence of one or more elements. The $names argument is a sequence of strings that represent attribute names to remove. Prefixes can (and must) be used in the $names values for attributes that are prefixed in the input documents (using the same prefix). You can also specify wildcard values "*", "*:" and ":*" as the second argument. See the description for functx:name-test for details.

The function does not remove attributes from the descendants of the elements, just the elements themselves; see functx:remove-attributes-deep for this purpose.
