ONSGMLS(1)                         Reference                        ONSGMLS(1)

       onsgmls - An SGML/XML parser and validator

       onsgmls [-BCdeghlnpRrsuvx] [-alinktype] [-Aarchitecture] [-bbctf] [-csysid...] [-Ddirectory] [-Emax_errors]
               [-ffile] [-iname] [-ooutput_option...] [-tfile] [-wwarning_type...] [sysid...]

       onsgmls parses and validates the SGML document whose document entity is specified by the system identifiers

       and prints on the standard output a simple text representation of its Element Structure Information Set. (This
        is the information set which a structure-controlled conforming SGML application should act upon.) If more than
        one system identifier is specified, then the corresponding entities will be concatenated to form the document
        entity. Thus the document entity may be spread among several files; for example, the SGML declaration, prolog
        and document instance set could each be in a separate file. If no system identifiers are specified, then
        onsgmls will read the document entity from the standard input. A command line system identifier of - can be
        used to refer to the standard input. (Normally in a system identifier, <OSFD>0 is used to refer to standard

       Part of an SGML System Conforming to International Standard ISO 8879 -- Standard Generalized Markup Language.
       An SGML Extended Facilities system conforming to Annex A of Internal Standard ISO/IEC 10744 --
       Hypermedia/Time-based Structuring Language

       The following options are available:

       -alinktype, --activate=linktype
           Make link type linktype active. Not all ESIS information is output in this case: the active LPDs are not
           explicitly reported, although each link attribute is qualified with its link type name; there is no
           information about result elements; when there are multiple link rules applicable to the current element,
           onsgmls always chooses the first.

       -Aarchitecture, --architecture=architecture
           Parse with respect to architecture architecture.

       -bbctf, --bctf=bctf, -bencoding, --encoding=encoding
           This determines the encoding used for output. If in fixed character set mode it specifies the name of an
           encoding; if not, it specifies the name of a BCTF.

       -B, --batch_mode
           Batch mode. Parse each

           specified on the command line separately, rather than concatenating them. This is useful mainly with -s.

            If -tfilename is also specified, then the specified filename will be prefixed to the sysid to make the
            filename for the RAST result for each sysid.

       -csysid, --catalog=sysid
           Map public identifiers and entity names to system identifiers using the catalog entry file whose system
           identifier is sysid. Multiple -c options are allowed. If there is a catalog entry file called catalog in
           the same place as the document entity, it will be searched for immediately after those specified by -c.

       -C, --catalogs

           arguments specify catalog files rather than the document entity. The document entity is specified by the
            first DOCUMENT entry in the catalog files.

       -Ddirectory, --directory=directory
           Search directory for files specified in system identifiers. Multiple -D options are allowed. See the
           description of the osfile storage manager for more information about file searching.

       -e, --open-entities
           Describe open entities in error messages. Error messages always include the position of the most recently
           opened external entity.

       -Emax_errors, --max-errors=max_errors
           onsgmls will exit after max_errors errors. If max_errors is 0, there is no limit on the number of errors.
           The default is 200.

       -ffile, --error-file=file
           Redirect errors to file. This is useful mainly with shells that do not support redirection of stderr.

       -g, --open-elements
           Show the generic identifiers of open elements in error messages.

       -h, --help
           Show a help message and exit.

       -iname, --include=name
           Pretend that

           <!ENTITY % name "INCLUDE">

           occurs at the start of the document type declaration subset in the SGML document entity. Since repeated
           definitions of an entity are ignored, this definition will take precedence over any other definitions of
           this entity in the document type declaration. Multiple -i options are allowed. If the SGML declaration
           replaces the reserved name INCLUDE then the new reserved name will be the replacement text of the entity.
           Typically the document type declaration will contain

           <!ENTITY % name "IGNORE">

           and will use %name; in the status keyword specification of a marked section declaration. In this case the
           effect of the option will be to cause the marked section not to be ignored.

       -n, --error-numbers
           Show message numbers in error messages.

       -ooutput_option, --option=output_option
           Output additional information according to output_option:

           entity Output definitions of all general entities not just for data or subdoc entities that are referenced
           or named in an ENTITY or ENTITIES attribute.

           id Distinguish attributes whose declared value is ID.

           line Output L commands giving the current line number and filename.

           included Output an i command for included sub-elements.

           empty Output an e command for elements which are not allowed to have an end-tag, that is those with a
           declared content of empty or with a content reference attribute.

           notation-sysid Output an f command before an N command, if a system identifier could be generated for that

           nonsgml In fixed character set mode, output \% escape sequences for non-SGML data characters. Non-SGML data
           characters can result from numeric character references.

           data-attribute Output the notation name and attributes for DATA attributes. Otherwise, DATA attributes are
           treated like CDATA attributes. For more details see clause 4.4.3 of Annex K of ISO 8879.

           comment Output an _ command with the contents of a comment. Multiple comments in a single comment
           declaration will result in multiple distinct _ commands, just as if the comments were each in a separate
           comment declaration.

           omitted Output an o command before a command which was implied by the input document, but omitted from the
           actual markup. This currently affects (,), and A commands.

           tagomit As omitted, but only for ( and ) commands.

           attromit As omitted, but only for A commands.

           Multiple -o options are allowed.

       -p, --only-prolog
           Parse only the prolog.  onsgmls will exit after parsing the document type declaration. Implies -s.

       -R, --restricted
           Restrict file reading. This option is intended for use with onsgmls-based Web tools (e.g. CGI scripts) to
           prevent reading of arbitrary files on the Web server. With this option enabled, onsgmls will not read any
           local files unless they are located in a directory (or subdirectory) specified by the -D option or included
           in the SGML_SEARCH_PATH environment variable. As a further security precaution, this option limits
           filesnames to the characters A-Z, a-z, 0-9, ???, ?.?, ?_?, ?-? and does not allow filenames containing
           "..". On systems with MS-DOS file names ?:? and ?\? are also allowed.

       -s, --no-output
           Suppress output. Error messages will still be printed.

       -tfile, --rast-file=file
           Output to file the RAST result as defined by ISO/IEC 13673:1995 (actually this isn?t quite an IS yet; this
           implements the Intermediate Editor?s Draft of 1994/08/29, with changes to implement ISO/IEC JTC1/SC18/WG8
           N1777). The normal output is not produced.

       -v, --version
           Print the version number.

       -wtype, --warning=type
           Control warnings and errors. Multiple -w options are allowed. The following values of type enable warnings:

           xml Warn about constructs that are not allowed by XML.

           mixed Warn about mixed content models that do not allow #PCDATA anywhere.

           sgmldecl Warn about various dubious constructions in the SGML declaration.

           should Warn about various recommendations made in ISO 8879 that the document does not comply with.
           (Recommendations are expressed with "should", as distinct from requirements which are usually expressed
           with "shall".)

           default Warn about defaulted references.

           duplicate Warn about duplicate entity declarations.

           undefined Warn about undefined elements: elements used in the DTD but not defined.

           unclosed Warn about unclosed start and end-tags.

           empty Warn about empty start and end-tags.

           net Warn about net-enabling start-tags and null end-tags.

           min-tag Warn about minimized start and end-tags. Equivalent to combination of unclosed, empty and net

           unused-map Warn about unused short reference maps: maps that are declared with a short reference mapping
           declaration but never used in a short reference use declaration in the DTD.

           unused-param Warn about parameter entities that are defined but not used in a DTD. Unused internal
           parameter entities whose text is INCLUDE or IGNORE won?t get the warning.

           notation-sysid Warn about notations for which no system identifier could be generated.

           all Warn about conditions that should usually be avoided (in the opinion of the author). Equivalent to:
           mixed, should, default, undefined, sgmldecl, unused-map, unused-param, empty and unclosed.

           immediate-recursion Warn about immediately recursive elements. For more detais see clause 2.2.5 of Annex K
           of ISO 8879.

           fully-declared Warn if the document instance fails to be fully declared. This has the effect of changing
           the SGML declaration to specify IMPLYDEF ATTLIST NO ELEMENT NO ENTITY NO NOTATION NO. For more details see
           clause 2.2.1 of Annex K of ISO 8879.

           fully-tagged Warn if the document instance fails to be fully-tagged. This has the effect of changing the
           OMITNAME NO. For more details see clause 2.2.2 of Annex K of ISO 8879.

           amply-tagged, amply-tagged-recursive Warn if the doucment instance fails to be amply-tagged. Implicitly
           defined elements may be immediately recurisve if amply-tagged-recursive is specified. This has the effect
           of changing the SGML declaration to specify DATATAG NO, RANK NO, OMITTAG NO, SHORTTAG ATTRIB OMITNAME NO
           and either IMPLYDEF ELEMENT ANYOTHER or IMPLYDEF ELEMENT YES. For more details see clause 2.2.4 of Annex K
           of ISO 8879.

           type-valid Warn if the document instance fails to be type-valid. This has the effect of changing the SGML
           declaration to specify VALIDITY YES. For more details see clause 2.2.3 of Annex K of ISO 8879.

           entity-ref Warn about references to non-predefined entities. This has the effect of changing the SGML
           declaration to specify ENTITIES REF NONE. For more details see clause 2.3.2 of Annex K of ISO 8879.

           external-entity-ref Warn about references to external entities. This includes references to an external DTD
           subset. This has the effect of changing the SGML declaration to specify ENTITIES REF INTERNAL. For more
           details see clause 2.3.3 of Annex K of ISO 8879.

           integral Warn if the document instance is not integrally stored. This has the effect of changing the SGML
           declaration to specify ENTITIES INTEGRAL YES. For more details see clause 2.3.1 of Annex K of ISO 8879.

           A warning can be disabled by using its name prefixed with no-. Thus -wall -wno-duplicate will enable all
           warnings except those about duplicate entity declarations.

           The following values for warning_type disable errors:

           no-idref Do not give an error for an ID reference value which no element has as its ID. The effect will be
           as if each attribute declared as an ID reference value had been declared as a name.

           no-significant Do not give an error when a character that is not a significant character in the reference
           concrete syntax occurs in a literal in the SGML declaration. This may be useful in conjunction with certain
           buggy test suites.

           no-valid Do not require the document to be type-valid. This has the effect of changing the SGML declaration
           to specify VALIDITY NOASSERT and IMPLYDEF ATTLIST YES ELEMENT YES. An option of -wvalid has the effect of
           changing the SGML declaration to specify VALIDITY TYPE and IMPLYDEF ATTLIST NO ELEMENT NO. If neither
           -wvalid nor -wno-valid are specified, then the VALIDITY and IMPLYDEF specified in the SGML declaration will
           be used.

           no-afdr Do not give errors when AFDR meta-DTD notation features are used in the DTD. These errors are
           normally produced when parsing the DTD, but suppressed when parsing meta-DTDs.

       -x, --references
           Show information about relevant clauses (from ISO 8879:1986) in error messages.

       The following options are also supported for backward compatibility with sgmls:

           Same as -wduplicate.

           Same as -oline.

           Same as -c.

           Same as -wdefault.

           Same as -wundef.
