xmlValidate
Validate a document in using a DTD, a Relax NG or a Schema.
Syntax
error = xmlValidate(docs [, valid])
Arguments
- docs
a mlist typed XMLDoc or a matrix of string containing path to XML documents
- valid
a mlist typed XMLValid.
- error
a matrix of string if an error occurred or []
Description
Validate an already parsed document or a set of documents with given paths with a DTD, a Relax NG or a Schema. If the document is valid, then the returned error is an empty matrix, else a matrix of strings is returned with the error message.
Validate a document with its path can improve performance and reduce the memory consumption.
It is not possible for the moment to validate a document against an external DTD. The only way to do this is to include in your XML file something like <!DOCTYPE foo SYSTEM "foo.dtd"> and to use xmlValidate without second argument.
Examples
doc = xmlRead("SCI/modules/xml/tests/unit_tests/library.xml"); dtd = xmlDTD("SCI/modules/xml/tests/unit_tests/library.dtd"); schema = xmlSchema("SCI/modules/xml/tests/unit_tests/library.xsd"); rng = xmlRelaxNG("SCI/modules/xml/tests/unit_tests/library.rng"); // We test if the document is valid // If no error the file is valid // DTD xmlValidate(doc, dtd); // Relax NG xmlValidate(doc, rng); // Schema xmlValidate(doc, schema); // All is ok... now we add a new element to the document doc.root.children(3) = "<a>error</a>" // Now the validations go to fail xmlValidate(doc, dtd); xmlValidate(doc, rng); xmlValidate(doc, schema); // You can validate a document with its path xmlValidate("SCI/modules/xml/tests/unit_tests/library.xml") xmlValidate("SCI/modules/xml/tests/unit_tests/invalid_library.xml") xmlValidate("SCI/modules/xml/tests/unit_tests/library.xml", schema) xmlValidate("SCI/modules/xml/tests/unit_tests/invalid_library.xml", rng) // We delete the all the open documents xmlDelete(doc, dtd, schema, rng);
