Break a URI into its 5 basic components according to the
RFC-3986 regular expression:
^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
12 3 4 5 6 7 8 9
If the schema is urn, it is broken into its schema, NSI
(Namespace Identifier) and NSS (Namespace Specific String).
- Arguments:
-
| Components | - is a one of
- uri_components(Scheme, Authority, Path, Search, Fragment)
- If a URI is parsed, i.e., using mode (+,-), components that
are not found are left uninstantiated (variable). See
uri_data/3 for accessing this structure.
- urn_components(Scheme, NID, NSS, Search, Fragment)
- Here Scheme is always
urn. Otherwise the same comments
as for uri_components/5 apply.
