Identifying source of parser errors in Apache Fuseki

Question

I am getting the following error in trying to load a large RDF/XML document into Fuseki:

> Code: 4/UNWISE_CHARACTER in PATH: The character matches no grammar rules of URIs/IRIs. These characters are permitted in RDF URI References, XML system identifiers, and XML Schema anyURIs.

How do I find out what line contains the offending error?

I have tried turning up the output in Log4j.properties and I also tried validating the RDF/XML file using the Jena commandline rdfxml tool (as well as utf8 & riot) --- it validates with no errors reported. But I'm new to this toolset.

(version?)

Check the ""-strings in your RDF/XML data for undesiravle URIs - especially spaces in URIs.

Best to validate before loading : try riot YourFile and send stderr and stdout to a file. The errors should be approximately in the position of the parser output (N-triples) at the time.
