It is included in \fBlibxml\fR(3)\&. .PP 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\&. .SH "OPTIONS" .PP \fBxmlcatalog\fR accepts the following options (in alphabetical order): .PP \fB\-\-add \fR\fB\fITYPE\fR\fR\fB \fR\fB\fIORIG\fR\fR\fB \fR\fB\fIREPLACE\fR\fR\fB \fR .RS 4 Add an entry to CATALOGFILE\&. \fITYPE\fR indicates the type of entry\&. Possible types are: \fIpublic\fR, \fIsystem\fR, \fIuri\fR, \fIrewriteSystem\fR, \fIrewriteURI\fR, \fIdelegatePublic\fR, \fIdelegateSystem\fR, \fIdelegateURI\fR, \fInextCatalog\fR\&. \fIORIG\fR is the original reference to be replaced, and \fIREPLACE\fR is the URI of the replacement entity to be used\&. The \fB\-\-add\fR option will not overwrite CATALOGFILE, outputting to stdout, unless \fB\-\-noout\fR is used\&. The \fB\-\-add\fR will always take three parameters even if some of the XML catalog constructs will have only a single argument\&. .RE .PP \fB\-\-add \fR\fB\fIFILENAME\fR\fR .RS 4 If the \fB\-\-add\fR option is used following the \fB\-\-sgml\fR option, only a single argument, a \fIFILENAME\fR, 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\&. .RE .PP \fB\-\-convert\fR .RS 4 Convert SGML catalog to XML\&. .RE .PP \fB\-\-create\fR .RS 4 Create a new XML catalog\&. Outputs to stdout, ignoring \fIfilename\fR unless \fB\-\-noout\fR is used, in which case it creates a new catalog file \fIfilename\fR\&. .RE .PP \fB\-\-del \fR\fB\fIVALUE(S)\fR\fR .RS 4 Remove entries from \fICATALOGFILE\fR matching \fIVALUE(S)\fR\&. The \fB\-\-del\fR option will not overwrite \fICATALOGFILE\fR, outputting to stdout, unless \fB\-\-noout\fR is used\&. .RE .PP \fB\-\-noout\fR .RS 4 Save output to the named file rather than outputting to stdout\&. .RE .PP \fB\-\-no\-super\-update\fR .RS 4 Do not update the SGML super catalog\&. .RE .PP \fB\-\-shell\fR .RS 4 Run a shell allowing interactive queries on catalog file \fICATALOGFILE\fR\&. For the set of available commands see the section called \(lqSHELL COMMANDS\(rq\&. .RE .PP \fB\-\-sgml\fR .RS 4 Uses SGML super catalogs for \fB\-\-add\fR and \fB\-\-del\fR options\&. .RE .PP \fB\-v\fR, \fB\-\-verbose\fR .RS 4 Output debugging information\&. .RE .PP Invoking \fBxmlcatalog\fR non\-interactively without a designated action (imposed with options like \fB\-\-add\fR) will result in a lookup of the catalog entry for \fIENTITIES\fR in the catalog denoted with \fICATALOGFILE\fR\&. The corresponding entries will be output to the command line\&. This mode of operation, together with \fB\-\-shell\fR mode and non\-modifying (i\&.e\&. without \fB\-\-noout\fR) direct actions, allows for a special shortcut of the void \fICATALOGFILE\fR specification (possibly expressed as "" in the shell environment) appointing the default system catalog\&. That simplifies the handling when its exact location is irrelevant but the respective built\-in still needs to be consulted\&. .SH "SHELL COMMANDS" .PP Invoking \fBxmlcatalog\fR with the \fB\-\-shell \fR\fB\fICATALOGFILE\fR\fR option opens a command line shell allowing interactive access to the catalog file identified by \fICATALOGFILE\fR\&. Invoking the shell provides a command line prompt after which the following commands (described in alphabetical order) can be entered\&. .PP \fBadd \fR\fB\fITYPE\fR\fR\fB \fR\fB\fIORIG\fR\fR\fB \fR\fB\fIREPLACE\fR\fR\fB \fR .RS 4 Add an entry to the catalog file\&. \fITYPE\fR indicates the type of entry\&. Possible types are: \fIpublic\fR, \fIsystem\fR, \fIuri\fR, \fIrewriteSystem\fR, \fIrewriteURI\fR, \fIdelegatePublic\fR, \fIdelegateSystem\fR, \fIdelegateURI\fR, \fInextCatalog\fR\&. \fIORIG\fR is the original reference to be replaced, and \fIREPLACE\fR is the URI of the replacement entity to be used\&. The \fB\-\-add\fR option will not overwrite CATALOGFILE, outputting to stdout, unless \fB\-\-noout\fR is used\&. The \fB\-\-add\fR will always take three parameters even if some of the XML catalog constructs will have only a single argument\&. .RE .PP \fBdebug\fR .RS 4 Print debugging statements showing the steps \fBxmlcatalog\fR is executing\&. .RE .PP \fBdel \fR\fB\fIVALUE(S)\fR\fR .RS 4 Remove the catalog entry corresponding to \fIVALUE(S)\fR\&. .RE .PP \fBdump\fR .RS 4 Print the current catalog\&. .RE .PP \fBexit\fR .RS 4 Quit the shell\&. .RE .PP \fBpublic \fR\fB\fIPUBLIC\-ID\fR\fR .RS 4 Execute a Formal Public Identifier lookup of the catalog entry for \fIPUBLIC\-ID\fR\&. The corresponding entry will be output to the command line\&. .RE .PP \fBquiet\fR .RS 4 Stop printing debugging statements\&. .RE .PP \fBsystem \fR\fB\fISYSTEM\-ID\fR\fR .RS 4 Execute a Formal Public Identifier lookup of the catalog entry for \fISYSTEM\-ID\fR\&. The corresponding entry will be output to the command line\&. .RE .SH "ENVIRONMENT" .PP \fBXML_CATALOG_FILES\fR .RS 4 XML catalog behavior can be changed by redirecting queries to the user\*(Aqs own set of catalogs\&. This can be done by setting the \fBXML_CATALOG_FILES\fR environment variable to a space\-separated list of catalogs\&. Use percent\-encoding to escape spaces or other characters\&. An empty variable should deactivate loading the default catalog from /etc/xml/catalog or, more specifically, ${sysconfdir}/xml/catalog\&. .RE .SH "DIAGNOSTICS" .PP \fBxmlcatalog\fR return codes provide information that can be used when calling it from scripts\&. .PP \fB0\fR .RS 4 No error .RE .PP \fB1\fR .RS 4 Failed to remove an entry from the catalog .RE .PP \fB2\fR .RS 4 Failed to save to the catalog, check file permissions .RE .PP \fB3\fR .RS 4 Failed to add an entry to the catalog .RE .PP \fB4\fR .RS 4 Failed to look up an entry in the catalog .RE .SH "SEE ALSO" .PP \fBlibxml\fR(3) .PP More information can be found at .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fBlibxml\fR(3) web page \m[blue]\fB\%https://gitlab.gnome.org/GNOME/libxml2\fR\m[] .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fBlibxml\fR(3) catalog support web page at \m[blue]\fB\%https://gitlab.gnome.org/GNOME/libxml2/-/wikis/Catalog-support\fR\m[] .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} James Clark\*(Aqs SGML catalog page \m[blue]\fB\%http://www.jclark.com/sp/catalog.htm\fR\m[] .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} OASIS XML catalog specification \m[blue]\fB\%http://www.oasis-open.org/committees/entity/spec.html\fR\m[] .RE .sp .SH "AUTHOR" .PP \fBJohn Fleck\fR <\&jfleck@inkstain\&.net\&> .RS 4 Author. .RE .SH "COPYRIGHT" .br Copyright \(co 2001, 2004 .br
