Method Detail

validate

public void validate(XMLGraph xg,
                     Grammar g)
              throws ConverterException

Validates an XML graph relative to a Restricted RELAX NG schema. More precisely, this checks that the language of the XML graph is included in the language of the schema. Violations are reported to the error handler. It is assumed that the XML graph is well-defined (see XMLGraph.check(PrintStream)) and that the grammar is restricted (see Grammar.check(PrintStream)). Note that this method works by first converting the schema into an XML graph - if the schema is used for multiple validations, the schema should be pre-converted and the method validate(XMLGraph,XMLGraph,int) should be used instead for better performance.

Parameters:

xg - XML graph

g - schema

Throws:

ConverterException - may be thrown if the schema is not restricted (see Grammar.check(PrintStream))

validate

public void validate(XMLGraph xg1,
                     XMLGraph xg2,
                     int xg2_root)

Validates an XML graph relative to another XML graph. More precisely, this checks that the language of the first XML graph is included in the language of the second XML graph. It is assumed that the first XML graph is well-defined (see XMLGraph.check(PrintStream)) and that the second XML graph has been constructed by RestrRelaxNG2XMLGraph. Violations are reported to the error handler.

Parameters:

xg1 - first XML graph, assumed to be non-unknown (i.e. isUnknown returns false)

xg2 - second XML graph

xg2_root - if -1, then use the roots of xg2, otherwise use this node as override
