invalid-data condition? action*
A rule used to process erroneous input. The DTD restricts where the data content is permitted to occur in an SGML instance. The
invalid-data rule is intended to process data content which violates these restrictions.
As with the selection of any other markup rule, the selection of an
invalid-data rule is determined by the currently active groups and the condition, if any, on each invalid data rule in an active group. The
%c operator is used in the body of the
invalid-data rule to capture the data in question, and either it or the
suppress action must be used (but only once).
If there are no
invalid-data rules in an OmniMark program, and invalid data is encountered, then the
marked-section ignore rules are examined as though the invalid data was the text of an ignore marked section.
OmniMark follows this procedure when invalid data is found:
invalid-datarule which can be performed, it processes the invalid data. If there are no
invalid-datarules at all, it searches for a
marked-section ignorerule to be performed, and processes the data. If there is no
marked-section ignorerule, the data is discarded.
The following is an example of invalid data:
<!doctype i [ <!element i - o (a)> <!element a - o (#pcdata)> ]> <i> <a> You are about to see invalid data. </a> This is invalid data <? Did you see the invalid data >
