XMLCATALOG(1)                                 xmlcatalog Manual                                XMLCATALOG(1)



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.

       0
           No error

       1
           Failed to remove an entry from the catalog

       2
           Failed to save to the catalog, check file permissions

       3
           Failed to add an entry to the catalog

       4
           Failed to look up an entry in the catalog
