java.lang.Object de.fuberlin.wiwiss.ng4j.trix.TriXParserWithExtensions
public class TriXParserWithExtensions
A parser for TriX files (see
TriX
specification). Parsed graphs and triples are passed to a
ParserCallback
for further processing.
The parser supports TriX syntactic extensions, which are XSLT stylesheets referenced using a processing instructions. The implementation loads the input document as a DOM tree, finds the processing instructions, applies the stylesheets if any are found, re-serializes the tree as XML, then parses again using a SAX parser. The reason for this waste of resources is that I didn't find a way to validate a DOM tree against an XML schema.
TODO: Implement syntactic extensions in a less braindead way
TODO: Have only one parse() method, with InputSource argument
