There is a SPARQL built-in for checking regexes:
http://www.w3.org/TR/rdf-sparql-query/#funcex-regexOn the local names question, I guess the URI splitting logic is buried somewhere in W3C namespace standards. Jena usually implements them correctly, so I guess local names cannot start with digits. Others on this list or the Jena list may know more.

Hi,I was wondering if there is a regex function that just matches patterns rather than matches and replaces? I have a need to find numbers in a string where I return the number if the string contains a number, otherwise I want to return the variable as unbound.Here is an example below. (Note I am calculating the local name as afn:localName doesn't work if the local name portion has numeric leading characters. Are leading numeric characters in a local name illegal?). Currently, if the regex doesn't find a match, it returns the input string. If I use the optional fourth parameter to say force the result to be an empty string, TBC throws an error (note that this only happens if the optional parameter is an empty string but works fine if I use a string of length 1 or more)bind(fn:substring(str(?s), spif:indexOf(str(?s), "#") + 2 )as ?localname) bind(spif:regex(?localname, "^\\D?(\\d+)([\\w -]*)", "$1") as ?name) Examples of local name inputs are: E4120-30 -> 4120 8500-TAGP -> 8500 DENISON -> No Match (unbound) Regards, Mark. -- You received this message because you are subscribed to the GoogleGroup "TopBraid Suite Users", the topics of which include Enterprise Vocabulary Network (EVN), TopBraid Composer,TopBraid Live, TopBraid Ensemble, SPARQLMotion and SPIN.
