Research Abstract |
We studied regular hedge languages (RHLs) as specification models of valid XML documents, and the possibility to use nonlinear regular hedge expression patterns to define a pattern-based query language for XML. We proposed new representations of RHLs, and algorithms for the computation of intersection, quotient, product derivative, and factors of RHLs. We have shown how to use RHL factorization to define a sound and complete type inference algorithm for the tuple of all variables in a nonlinear regular hedge expression pattern.
