How to parse XML file using SAX Parser and also applying DTD validation. parser Validating(true); line gives Parserconfigurationexception in android and give warning that no implementation of validation is supported. Is there any other method to give dtd validation in android? The class first needs to be instantiated using the new Instance() method. A call to its new SAXParser() then provides a Note that despite the ability to query the validation feature, there is currently no validating parser available.spf = SAXParser Instance(); Validating(false); Feature(" false); Feature(" true); Feature(" false); SEVERE: null sax.SAXParse Exception: The entity "nbsp" was referenced, butnot declared. Abstract SAXParser.parse(Abstract SAXParser.java:1231) at org.apache.xerces. SAXParser Impl$JAXPSAXParser.parse(SAXParser Impl.java:522) I can understand that it can't find the entity, since I told the factory to not read the DTD, but how do I disable entity checking alltogther?) as defined below has been used in the code examples to validate the input document.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.I need to parse a bunch of incoming XML documents but it does not contain DTD declaration. How can I validate an XML file using DTD created by myself (SAX parser) ?Currently I am parsing xml documents using SAX Parser but without DTD validation. I found some tutorials using Transformer but all for DOM Parser.
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.This is different from DTD validation where errors, and in particular, validation errors, are not reported.Configure Java APIs (SAX, DOM, dom4j, XOM) using JAXP 1.3 to validate XML Documents with DTD and Schema(s).EDIT: This is for an Android app, which is why I am reluctant to use an API/library that isn't in the standard environment.SAX doesn't seem capable of this, but the St AX API does.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.I think it is possible to intercept these errors by writing your own DOMError Handler instance - more details here: used this approach to work around a problem whereby I'm parsing a drawing as a XML SVG document generated by Corel Draw 12 which breaks the SVG DTD rules sometimes in the documents it outputs. Is that because you don't want it to access this from the W3C servers by connecting to the internet; you want a standalone, off-network solution with a local DTD?Submit a bug or feature For further API reference and developer documentation, see Java SE Documentation. See this previous question/answer for how to set this up.If you're writing the XML processor by hand, the St AX API is a lot easier to deal with than the SAX API, so you win on both counts. What would you expect the SAX parser to do given that it doesn't understand this entity at all.
