sgml2xml - convert SGML to XML
An SGML System Conforming to International Standard ISO 8879 -- Stan-
dard Generalized Markup Language
sgml2xml [ -Cehilprvx ] [ -bencoding ] [ -ccatalog ] [ -Ddir ] [
-ffile ] [ -iname ] [ -wwarning ] [ -xxml-output-option ] sysid...
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.
Use encoding for output. The default is UTF-8. See nsgmls(1)
for the possible encoding types.
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.
Search directory for files specified in system identifiers. Mul-
tiple -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 dec-
laration 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.
Control the XML output, according to the value of xml_out-
put_option as follows:
Don't use newlines inside start-tags. Usually sgml2xml
uses newlines inside start-tags so as to reduce the prob-
ability of excessively long lines.
id Output attribute declarations for ID attributes.
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
cdata Use XML CDATA sections for CDATA marked sections and for
elements with a declared content of CDATA.
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.
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
Output a ATTLIST declaration for every element specifying
the type of all attributes. The default will always be
Multiple -x options are allowed.
