export catch compile-error (value integer error-code,
value string error-message,
value string error-detail)
compile-error exception is thrown by compile-schema if the
schema is not a valid RELAX NG schema. The following example demonstrates how
compile-error can be
used to make processing more robust.
import "omrelaxng.xmd" prefixed by relaxng.
local relaxng.relaxng-schema-type example-schema
do xml-parse scan file "example-input.xml"
set example-schema to relaxng.compile-schema file "example-schema.rng"
do markup-parse relaxng.validated #content against example-schema
catch relaxng.compile-error (code, message, detail)
log-message "Input processing will proceeed without validation because of a schema compilation error:%n"
do markup-parse #content
