split-external-text-entities

function

Library: Markup utilities (OMMARKUPUTILITIES)
Import : ommarkuputilities.xmd

Returns: a markup sink to be split

Declaration

export markup sink function
 split-external-text-entities (value markup sink entity-markup,
 value markup sink other-markup)

Purpose

Use split-external-text-entities to split a markup stream in two, one containing only external text entity references and the other everything else.

Example

In this example we parse an SGML file and split the resulting #content markup stream using split-external-text-entities. The external text entity markup events are sent to markup sink function resolve-entities and the remaining markup to function process-markup.

 import "ommarkuputilities.xmd" unprefixed
 
 define markup sink function
 resolve-entities
 as
 using group "resolve entities"
 do markup-parse #current-input
 output "%c"
 done
 
 define markup sink function
 process-markup
 as
 using group "process markup"
 using output as file "output.txt"
 do markup-parse #current-input
 output "%c"
 done
 
 process
 do sgml-parse document scan file "input.sgml"
 using output as split-external-text-entities (resolve-entities, process-markup)
 output #content
 done
 
 group "resolve entities"
 external-text-entity #implied
 output file "%eq"
 
 group "process markup"
 element #implied
 output "%c"
