How to split a urlencoded ";-" separated list of urls in a SPARQL query? Assume the following string: UNKNOWN tag: http://www.w3.org/1999/xhtml:verbartim "http://example.org/test1;http://example.org/test2". In order to split the given string into two values i.e. http://example.org/test1 and http://example.org/test2 , one should use the Virtuoso function split_and_decode() which returns an array. Thus the Virtuoso function aref() also needs to be used for loading the elements. Example: SELECT bif:aref (bif:split_and_decode('http%3A%2F%2Fexample.org%2Ftest1%3Bhttp%3A%2F%2Fexample.org%2Ftest2',0), 0) { ?S ?P ?O } LIMIT 1 View the SPARQL Query Definition via SPARQL Protocol URL; View the SPARQL Query Results via SPARQL Protocol URL Related Virtuoso Tips and Tricks Collection Virtuoso Documentation
