SYNOPSIS

sgml2xml [ -Cehilprvx ] [ -bencoding ] [ -ccatalog ] [ -Ddir ] [ -ffile ] [ -iname ] [ -wwarning ] [ -xxml-output-option ] sysid...

DESCRIPTION

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.

Multiple -x options are allowed.
