NAME
xmlcatmgr - XML and SGML catalog manager
SYNOPSIS
xmlcatmgr [-hpsv] [-c catalog] action [action_arg ...]
DESCRIPTION
xmlcatmgr is a utility used to manipulate SGML and XML catalogs. It is
designed with simplicity in mind: it does not depend on external programs
nor libraries. This manpage corresponds to xmlcatmgr version 2.2.
A catalog is a lookup mechanism used to translate entities into other
different entities. They can, for example, map public identifiers to
local files or URIs. This allows you to tell the parser where to look
for entities without having to modify the original document source.
Catalogs come in two different formats: SGML catalogs and XML catalogs.
The former are supported by many programs, as are very easy to parse and
have existed for a long time. XML catalogs are quite recent and are much
more powerful than the others. xmlcatmgr can manage both of them, but
its default behavior is to handle XML catalogs (hence, the name of the
program).
The following options are available:
-c catalog Use catalog as the catalog file. If not specified, the
catalog defaults to /usr/local/share/xml/catalog.ports if
running in XML mode, or to
/usr/local/share/sgml/catalog.ports if running in SGML mode
(see the -s flag).
-h Show a descriptive usage message and exit.
-p When adding a new entry to a catalog (using the add action),
prepend it instead of inserting it at the end.
-s Use the standard SGML catalog format to parse the catalog,
instead of the XML format.
-v Show version information and exit.
The action argument specifies what to do with the catalog file. It is
mandatory and may require extra arguments. The action name can be
preceded by the `--' string, to maintain some compatibility with the
xmlcatalog utility included in the libxml2 package.
The following actions are available:
add type orig replace Add an entry to the catalog. type specifies the
type of entry (see below), orig is the public
identifier to be replaced and replace is the
system URI used to do the replacement.
If replace is the `--' string, it is ignored.
This is specially useful in scripts, as you can
parse three arguments at a time regardless the
current type expectations.
If all entries can be added successfully, the
program returns 0; otherwise >0.
create Create an empty catalog. Produces an error if it
already exists.
destroy Delete the catalog file.
lookup value Check if given entries exist in the catalog,
specified by their value argument. This matches
the value passed to orig when using the `add'
action. All entries found are printed to standard
output.
Note that this action does not recurse into
catalogs, nor does network lookups. It is only
provided to check if entries exist in an specific
catalog, to decide if they should be registered or
not.
If all entries exist, the program returns 0;
otherwise >0.
remove type value Remove entries from the catalog, specified by
their type and their value. The former provides
the type of entry (see below), while the later
matches the value passed in the orig parameter
when using the `add' action.
If just one argument is provided, all matching
entries are removed, regardless their type. This
is only provided for command line compatibility
with all previous versions, so do not use it any
more (a warning message will be shown).
If all entries were removed successfully, the
program returns 0; otherwise >0.
When parsing SGML catalogs, the type used by `add' and `remove' actions
can be one of the following: `BASE', `CATALOG', `DELEGATE', `DOCTYPE',
`DOCUMENT', `ENTITY', `LINKTYPE', `NOTATION', `OVERRIDE', `PUBLIC',
`SGMLDECL' and `SYSTEM'. When parsing XML catalogs, it can be:
`delegatePublic', `delegateSystem', `delegateURI', `group' (not
supported), `nextCatalog', `public', `rewriteSystem', `rewriteURI',
`system' and `uri'.

HISTORY
xmlcatmgr was created because the NetBSD Packages Collection needed a
very small catalog manager to automatically (un)register catalog entries
when (de)installing packages.
It was released as an independant program through Sourceforge in the hope
that it is useful to more people.
For a list of changes between versions, see:
/usr/local/share/doc/xmlcatmgr/CHANGES.
