I solved in this way:

result = result.replaceAll("(<rdf:type rdf:resource=\"([^<]*)\"/>)", "<process:valueType rdf:datatype=\"http://www.w3.org/2001/XMLSchema#anyURI\">$2</process:valueType>");

I would use lookbehind to find rdf:datatype and select everything other than " which is actually the end of the value, something like this:

(?<=datatype=\")[^\"]*

you can do that with lookahead to:

(?<=datatype=\").*(?=\")
