If you want Semantic XML to re-use your existing classes and properties, then you need to "annotate" those classes with sxml:attribute and sxml:element values. In order to see which triples are needed, open your XML file in TBC-ME (using Semantic XML- double click on the .xml should do it), and analyze the resulting ontology. The generated classes should have sxml:element values on them, and the importer will try to re-use existing classes if they already have those tags.
