DESCRIPTION
onsgmls parses and validates the SGML document whose document entity is
specified by the system identifiers .nf .fi and prints on the standard
output a simple text representation of its Element Structure Informa-
tion 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 con-
catenated 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 sys-
tem 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 iden-
tifier, <OSFD>0 is used to refer to standard input.)
The following options are available:
-alinktype, --activate=linktype
Make link type linktype active. Not all ESIS information is out-
put 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, ons-
gmls 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 char-
acter 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 .nf .fi 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
The .nf .fi 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. Mul-
tiple -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 decla-
ration. 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 docu-
ment 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 file-
name.
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 notation.
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. Mul-
tiple 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 docu-
ment type declaration. Implies -s.
-R, --restricted
Restrict file reading. This option is intended for use with ons-
gmls-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 fur-
ther security precaution, this option limits filesnames to the
characters A-Z, a-z, 0-9, '?', '.', '_', '-' and does not allow
filenames containing "..".
-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 Inter-
mediate 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 warnings.
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 identi-
fier 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 SGML declaration to
specify DATATAG NO, RANK NO, OMITTAG NO, SHORTTAG STARTTAG EMPTY
NO and SHORTTAG ATTRIB 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 speci-
fied. This has the effect of changing the SGML declaration to
specify DATATAG NO, RANK NO, OMITTAG NO, SHORTTAG ATTRIB OMIT-
NAME 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 con-
junction 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 spec-
ify 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:
-d Same as -wduplicate.
-l Same as -oline.
-msysid
Same as -c.
-r Same as -wdefault.
-u Same as -wundef.
