lxuniq removes repeated elements in an XML document.
The domain-query is an XPath that identifies
elements within which removal is done. Within each domain the
element-query is used to select elements to
be compared. For each element the key-query is
evaluated to to produce a key, and if two or more successive elements have the
same key (compared as strings), all but the first are removed.
The input-file argument may be a URI instead of a filename. If no input-file argument is given, standard input is used.
The domain-query is streamed. The subtree rooted at
each matching element is read, and is available to the
element-query and key-query.
binds a prefix (or the default namespace) to a URI for use in XPath queries.
