# sgml2xml-isoent(1)

Convert SGML to XML with support for ISO entities

## NAME

sgml2xml-isoent - Convert SGML to XML with support for ISO entities

## SYNOPSIS

**sgml2xml-isoent**  \[*sgml-document*\]

## DESCRIPTION

**sgml2xml-isoent** converts an SGML document to XML, with support for the ISO entities. This is done by using  [**sgml2xml**(1)](/sgml2xml/1.md) from the SP package (or  [**osx**(1)](/osx/1.md) from the OpenSP package), and the declaration for the XML version of the ISO entities is added to the output. This means that the output of this conversion should work as-is with any XML tool.

This program is often used for processing SGML DocBook documents with XML-based tools. In particular, [**db2x\_xsltproc**(1)](/db2x_xsltproc/1.md) calls this program as part of its FC**--sgml**F\[0\] option. On the other hand, it is probably not helpful for  migrating a source SGML text file to XML, since the conversion  mangles the original formatting.

Since the XML version of the ISO entities  are referred to directly, not via a DTD, this tool  also works with document types other than DocBook.

## NOTES

The ISO entities are referred using the public identifiers  FCISO 8879:1986//ENTITIES//*...*//EN//XMLF\[0\].  The catalogs used when parsing the converted document should  resolve these entities to the appropriate place (on the local filesystem). If the entities are not resolved in the catalog,  then the fallback is to get the entity files from the FChttp://www.docbook.org/F\[0\] Web site.
