The article explores the complexities inherent to automated testing for XML processors, emphasizing the vulnerabilities in XPath expression evaluations. Through a detailed running example involving an XML document and various XML processors, the authors illustrate how discrepancies can arise in query results, specifically showing how BaseX differs from other processors. The paper further delves into XML's structure and the critical role of XPath in navigating XML data, establishing a basis for understanding automated testing's implications in achieving accurate data retrieval across diverse XML processors.
This example highlights the challenges of automated testing with XML processors, illustrating how different processors return divergent results for the same XPath query.
XML serves as a highly structured format, enabling data representation through nodes and attributes, requiring precise navigation using XPath for effective querying.
