  processing-instruction pattern condition?
     action*

A rule selected when a processing instruction occurs whose entire text matches the specified pattern and the specified condition is satisfied. As with other rules, OmniMark performs processing-instruction rules in the order in which they occur in the program.

processing-instruction rules are not permitted in cross-translations.

Suppose an SGML document contained "<?newpage>" processing instructions. An OmniMark down-translation that processes these processing instructions could contain the following rule:

  processing-instruction "newpage"
     output "\newpage{}"

Suppose an XML document contained "<?newpage?>" processing instructions. An OmniMark down-translation that processes these processing instructions could contain the same rule as the one we used for SGML, because OmniMark processes XML and SGML with the same syntax.

The following example illustrates recreating the original processing instruction entity reference if a processing instruction was entered with such a reference, and recreating the processing instruction itself in all other cases:

  processing-instruction named any* => pi-entity-name
     output "&%g(pi-entity-name);"
  processing-instruction valued any* => pi-text
     output ""
