Hi Matiam, if you're using Maven, you'd just need to declare the following dependency:
<dependency> <groupId>org.openrdf.sesame</groupId> <artifactId>sesame-queryresultio-sparqlxml</artifactId> <version>2.7.13</version> <scope>runtime</scope> </dependency> and then the parser factory should be automatically registered. I've just pushed the patch for the current 3.4.0-SNAPSHOT. So from the next release this would not be necessary.
