NAME

       xmlcatalog - Command line tool to parse and manipulate XML or SGML catalog files.

SYNOPSIS

       xmlcatalog [--sgml | --shell | --create | --del VALUE(S) |
                  [ --add TYPE ORIG REPLACE  | --add FILENAME] | --noout | --no-super-update |
                  [-v | --verbose]] {CATALOGFILE} {ENTITIES...}

DESCRIPTION

       xmlcatalog is a command line application allowing users to monitor and manipulate XML and
       SGML catalogs. It is included in libxml(3).

       Its functions can be invoked from a single command from the command line, or it can
       perform multiple functions in interactive mode. It can operate on both XML and SGML files.

OPTIONS

       xmlcatalog accepts the following options (in alphabetical order):

       --add TYPE ORIG REPLACE
           Add an entry to CATALOGFILE.  TYPE indicates the type of entry. Possible types are:
           public, system, uri, rewriteSystem, rewriteURI, delegatePublic, delegateSystem,
           delegateURI, nextCatalog.  ORIG is the original reference to be replaced, and REPLACE
           is the URI of the replacement entity to be used. The --add option will not overwrite
           CATALOGFILE, outputting to stdout, unless --noout is used. The --add will always take
           three parameters even if some of the XML catalog constructs will have only a single
           argument.

       --add FILENAME
           If the --add option is used following the --sgml option, only a single argument, a
           FILENAME, is used. This is used to add the name of a catalog file to an SGML
           supercatalog, a file that contains references to other included SGML catalog files.

       --create
           Create a new XML catalog. Outputs to stdout, ignoring filename unless --noout is used,
           in which case it creates a new catalog file filename.

       --del VALUE(S)
           Remove entries from CATALOGFILE matching VALUE(S). The --del option will not overwrite
           CATALOGFILE, outputting to stdout, unless --noout is used.

       --noout
           Save output to the named file rather than outputting to stdout.

       --no-super-update
           Do not update the SGML super catalog.

       --shell
           Run a shell allowing interactive queries on catalog file CATALOGFILE. For the set of
           available commands see the section called “SHELL COMMANDS”.

       --sgml
           Uses SGML super catalogs for --add and --del options.

       -v, --verbose
           Output debugging information.

SHELL COMMANDS

       Invoking xmlcatalog with the --shell CATALOGFILE option opens a command line shell
       allowing interactive access to the catalog file identified by CATALOGFILE. Invoking the
       shell provides a command line prompt after which the following commands (described in
       alphabetical order) can be entered.

       add TYPE ORIG REPLACE
           Add an entry to the catalog file.  TYPE indicates the type of entry. Possible types
           are: public, system, uri, rewriteSystem, rewriteURI, delegatePublic, delegateSystem,
           delegateURI, nextCatalog.  ORIG is the original reference to be replaced, and REPLACE
           is the URI of the replacement entity to be used. The --add option will not overwrite
           CATALOGFILE, outputting to stdout, unless --noout is used. The --add will always take
           three parameters even if some of the XML catalog constructs will have only a single
           argument.

       debug
           Print debugging statements showing the steps xmlcatalog is executing.

       del VALUE(S)
           Remove the catalog entry corresponding to VALUE(S).

       dump
           Print the current catalog.

       exit
           Quit the shell.

       public PUBLIC-ID
           Execute a Formal Public Identifier look-up of the catalog entry for PUBLIC-ID. The
           corresponding entry will be output to the command line.

       quiet
           Stop printing debugging statements.

       system SYSTEM-ID
           Execute a Formal Public Identifier look-up of the catalog entry for SYSTEM-ID. The
           corresponding entry will be output to the command line.

ENVIRONMENT

       XML_CATALOG_FILES
           XML catalog behavior can be changed by redirecting queries to the user's own set of
           catalogs. This can be done by setting the XML_CATALOG_FILES environment variable to a
           list of catalogs. An empty one should deactivate loading the default /etc/xml/catalog
           catalog.

DIAGNOSTICS

       xmlcatalog return codes provide information that can be used when calling it from scripts.
