3.21.3 Adding rules for html//1

In some cases it is practical to extend the translations imposed by html//1. We used this technique to define translation rules for the output of the SWI-Prolog library(sgml) package.

The html//1 non-terminal first calls the multifile ruleset html_write:expand//1.

html_write:expand(+Spec)//

Hook to add additional translation rules for html//1.

html_quoted(+Atom)//

Emit the text in Atom, inserting entity-references for the SGML special characters <&>.

html_quoted_attribute(+Atom)//

Emit the text in Atom suitable for use as an SGML attribute, inserting entity-references for the SGML special characters <&>".
