Classes

Class schema

An instance of this class represents a Relax NG grammar that has been parsed and simplified.

Class rng-error

The class of all validation and schema parsing errors. ...

Class dtd-compatibility-error

The class of DTD compatibility errors. ...

Parsing and validating

Function parse-schema (input &key entity-resolver (process-dtd-compatibility t))

This function parses a Relax NG schema file in XML syntax ...

Function parse-compact (pathname)

This function parses a Relax NG schema file in compact syntax ...

Function make-validator (schema &optional handler)

This function creates a validation handler for schema ...

Function make-dtd-compatibility-handler (schema handler)

This function creates a handler for DTD Compatibility processing ...

Grammar introspection

The following classes and function are exported so that users can take a peek at the internals of the parsed and simplified grammar.

Function schema-start (instance)

Reader function for the grammar's start pattern, from which all of the grammar's patters are reachable.

Class attribute

This pattern specifies that an attribute of a certain name class is required. ...

Class choice

This pattern specifies that one of two possible subpatterns are allowed at the current position, given as its children. ...

Class data

This pattern specifies that text of a specific data type is expected. ...

Class element

This pattern specifies that an element of a certain name class is required. ...

Class empty

This pattern specifies that nothing more is expected at the current position. ...

Class group

This pattern specifies that two subpatterns are required at the current position in a specific order. ...

Class interleave

This pattern specifies that two possible subpatterns are allowed to occur in any order at the current position. ...

Class list-pattern

This pattern specifies that a subpatterns is allowed multiple times a the current position, with whitespace as a separator. ...

Class not-allowed

This pattern specifies that the part of the schema reached at this point is not valid. ...

Class one-or-more

This pattern specifies that its subpattern is allowed to occur at the current position one or more times. ...

Class pattern

The superclass of all patterns. ...

Class ref

This pattern references another part of the pattern graph. ...

Class text

This pattern specifies that text is expected here. ...

Class value

This pattern specifies that a specific value is expected as text here. ...

Function pattern-child (instance)

Returns the pattern's sub-pattern. ...

Function pattern-a (instance)

Returns the first of two sub-patterns the pattern instance has. ...

Function pattern-b (instance)

Returns the second of two sub-patterns the pattern instance has. ...

Function pattern-name (instance)

Returns the pattern's name class. ...

Function pattern-element (ref)

Returns the ref pattern's target. ...

Function pattern-type (instance)

Returns the data type expected at this position. ...

Function pattern-string (instance)

Returns the string expected at this position. ...

Function pattern-value (instance)

Returns the value expected at this position. ...

Function pattern-params (instance)

The data type parameters for this data pattern. ...

Function pattern-except (instance)

Returns the data instance's except pattern. ...
