Abstract The following paper presents a solution resolving inconsistencies in processing XML data-structures with SBQL objectoriented query and programming language. SBQL is based on Stack-Based Architecture (SBA) a formal approach reconstructing query languages’ concepts from the point of view of programming languages (Pls). The basic data store model AS0 defined in SBA can describe complex hierarchical data structures implied by XML. Nevertheless, in the classical approach to processing XML some use-case scenarios cannot be solved in satisfactory manner. In such cases SBQL queries return results either typologically obscure from the point of view of SBA or invalid from the point of view of expected XML tags formatting. The paper illustrates this problem on comprehensive examples, presents its cause and the solution.
