find-start condition? action*
find-start rule in an OmniMark program specifies actions to be performed at the beginning of processing an input document.
find-start rules are automatically invoked on the main input of a cross-translation, up-translation, or context-translation. A
find-start rule is allowed only in up-translation, cross-translation, or context-translation programs .
The condition in the header of a
find-start rule can depend on switches set on the command line, streams opened on the command line, and actions in previously performed
More than one
find-start rule can appear in a program: those whose conditions succeed are performed in the order in which they appear in the OmniMark program. No condition need be specified for a
find-start rule if none is relevant.
In context-translations or up-translations, initialization actions analogous to those performed in a
find-start rule can also be performed using
document-start rules. All
document-start rules are performed before
find-start rules. This allows
find-start rules to generate SGML markup which is processed by
element rules, while still ensuring that
document-start rules are processed before any markup.
find-end rules can be used for termination,
find-start rules can be used for initialization.
