Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).Many Java XML APIs provide mechanisms to validate XML documents, the JAXP API can be used for most of these XML APIs but subtle configuration differences exists.The input document contains an extra attribute which has not been defined in the XML Schema, this shows that the XML Schema has been used for the validation.When using this XML Schema to validate the input XML document, the following error gets reported: ) as defined below has been used in the code examples to validate the input document.The Error Handler used for the examples is a very simple one which reports the error to and continues until the XML document has been fully parsed or until a fatal-error has been reported.Namespaces have been introduced to XML after the first specification of XML had received the official W3C Recommendation status.This is the reason why (most of the) XML parser implementations do not support XML Namespaces by default, to handle the validation of XML documents with namespaces correctly it is therefore necessary to configure the underlying parsers to provide support for XML Namespaces.
"bogus") then Oxygen no longer validates my document through the DTD.However, if you are working with a language that is not known to Eclipse, it will be unable to validate the document.It will only be able to ensure that the document is well-formed.It would be very very odd if you would load a DTD in variable 'p', not use that variable in any way and python will magically know that that is the DTD you want to validate with. /usr/bin/env python from xml.parsers.xmlproc import xmlproc from xml.parsers.xmlproc import xmlval from xml.parsers.xmlproc import xmldtd def validate_xml(xml_filename, dtd_filename): """Validate a given XML file with a given external DTD.If the XML file is not valid, an error message will be printed to sys.stderr, and the program will be terminated with a non-zero exit code.
