sgml2xml converts SGML to XML.
sgml2xml parses and validates the SGML document contained in
sysid... and writes an equivalent XML document to the
standard output. sgml2xml will warn about SGML constructs
which have no XML equivalent.
OPTIONS
-bencoding
Use encoding for output.
The default is UTF-8. See nsgmls(1) for the possible encoding types.
-ccatalog
Use the catalog entry file
file.
-C
The filename... arguments specify catalog files rather
than the document entity. The document entity is specified by the first
DOCUMENT entry in the catalog files.
-Ddirectory
Search directory for files specified in system
identifiers. Multiple -D options are allowed. See nsgmls(1)
for more information about this option.
-e
Describe open entities in error messages.
-ffile
Redirect errors to file.
This is useful only for shells that do not
support redirection of stderr.
-iname
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.
-v
Print the version number.
-wtype
Control warnings and errors according to
type.
See nsgmls(1) for the allowed values of type.
-xxml-output-option
Control the XML output, according to the value of
xml_output_option as follows:
no-nl-in-tag
Don't use newlines inside start-tags. Usually sgml2xml
uses newlines inside start-tags so as to reduce the probability of
excessively long lines.
id
Output attribute declarations for ID attributes.
notation
Output declarations for notations.
ndata
Output declarations for external data entities. XML requires these
to be NDATA. sgml2xml will warn about CDATA
and SDATA external data entities and output them as NDATA entities.
cdata
Use XML CDATA sections for CDATA marked sections
and for elements with a declared content of CDATA.
comment
Output comment declarations. Comment declarations in the DTD will
not be output.
lower
Prefer lower case. Names that were subjected to upper-case substitution
by SGML will be folded to lower case. This does not include reserved
names; XML requires these to be in upper-case.
pi-escape
Escape &<> in the contents of
processing instructions using the amp, lt and
gt entities. This allows processing instructions to
contain the string >?, but requires that applications
handle the escapes.
empty
Use the <e/> syntax for element
types e declared as EMPTY.
attlist
Output a ATTLIST declaration for every element
specifying the type of all attributes. The default will always be
#IMPLIED.
