NAME
xmlns - replace XML Namespace prefixes by "global
names"
SYNOPSIS
xmlns [ -d ] [ -- ] [
file ]
DESCRIPTION
xmlns expands all element and attribute
names to "global names" by expanding the prefix. All names will be
printed as "{URL}name". Attribute names without a prefix will have
an empty namespace part: "{}name". The namespace attributes (those
that start with "xmlns") will be removed.
By default comments, PIs and the doctype declaration are
removed, but with option -d they are kept unchanged.
