dtd

I'm trying to use xmltask for ant to modify a file in a subdirectory: project/path/to/file.xml The file refers to a DTD like this: <!DOCTYPE data SYSTEM "mydtd.dtd"> I don't have the flexibility to change these documents. This DTD is stored in the same subdirectory, which has always worked fine: project/path/to/mydtd.dtd Unfortunately, xmltask is trying to locate the dtd in my project's top-level directory, which is where my build file is located, and where I run from: [xmltask] java.io.FileNotFoundException: /home/me/project/mydtd.dtd (The system cannot find the file specified) I see in the

Does the following propositions hold: For every DTD there is an XSD that defines exactly the same language, and for every XSD there is a DTD that defines exactly the same language. Or put another way: The collection of languages defined by any DTD is exactly the the collection of languages defined by any XSD? Expanding on the question a little: An XML document is basically a large string. A language is a collection of strings. For example, the (infinite) set of all MathML documents is a language, and so is the set of all RSS documents and so on. MathML (RSS, ...) is also a proper subset of the

I am trying to validate an xml file via a .dtd. I have write this validator: public bool Validation(XmlDocument xmlDoc) { var xml = XmldocToString(xmlDoc); var r = new XmlTextReader(new StringReader(xml)); var settings = new XmlReaderSettings(); var sb = new StringBuilder(); settings.ProhibitDtd = false; settings.ValidationType = ValidationType.DTD; settings.ValidationEventHandler += (a, e) => { sb.AppendLine(e.Message); _isValid = false; }; XmlReader validator = XmlReader.Create(r, settings); while (validator.Read()) { } validator.Close(); return _isValid; } The problem is that I must have

I have some XML that I'm parsing with a SAX parser in Java. It starts with this preamble: <!DOCTYPE math PUBLIC "-//W3C//DTD MathML 3.0//EN" "http://www.w3.org/Math/DTD/mathml3/mathml3.dtd"> How do I change this to use a local DTD? I suppose I could do something like this: <!DOCTYPE math PUBLIC "-//W3C//DTD MathML 3.0//EN" "file:///c:/MathML/mathml3.dtd"> Not exactly like that, but something like that. However, I need the path to be independent of the user's system. How do I use a local DTD with a path relative to the class path? Take a look at this article on using XML catalogs to resolve

I'm trying to write a validation script that will validate XML against the NITF DTD, http://www.iptc.org/std/NITF/3.4/specification/dtd/nitf-3-4.dtd . Based on this post I came up with the following simple script to validate a NITF XML document. Bellow is the error message I get when the script is run, which isn't very descriptive and makes it hard to debug. Any help is appreciated. #!/usr/bin/env python def main(): from lxml import etree, objectify from StringIO import StringIO f = open('nitf_test.xml') xml_doc = f.read() f.close() f = open('nitf-3-4.dtd') dtd_doc = f.read() f.close() dtd =

I am building a Struts2 web application which uses tiles however I have discovered a quite frustrating problem where if apache.org is down (which seems to happen quite regularly) the web application fails to start. This is because in its standard setup the StrutsTilesListener tries to load the tiles defenitions file which includes a DOCTYPE with a public-id which points to a DTD located on tiles.apache.org. When the application starts up the definition file is loaded using Apache Xerces via Apache Commons Digester which tries to load the DTD from tiles.apache.org but if apache.org is down then
