In the web services environment software development can involve writing both object-oriented programs and XML transformations. This can be seen in the popular Web Services architecture. In this architecture, crosscutting concerns are often manifest as transformations on XML messages; encrypting messages, adapting between schemas types or adding extrafunctional elements such as transaction contexts can be seen as prime examples. Some existing middleware platforms provide support for Handlers where crosscutting message transformation concerns can be addressed. Although handlers localize some concerns, they do not support the sound software-engineering principle of "programming to an interface". This prevents a clean mapping from design to implementation and inhibits useful static checking which could take advantage of a well specified interface. To address this and similar design challenges, we have developed Doxpects, which solve many problems with the existing handler approach to implementing these new crosscutting concerns. We describe an AOP abstraction called the content-based pointcut which integrates support for XML transformation to enable implementation of crosscutting concerns with good modularity properties. We present examples based on XML encryption and service interoperability implemented on top of the Apache Axis Web Services middleware. 1 JAX-RPC

The popularity of XML has motivated the development of novel XML processing tools many of which embed the XPath language for XML querying, transformation, constraint specification, etc. XPath developers (as well as less technical users) have access to commercial tools to help them use the language effectively. Example tools include debuggers that return the result of XPath subexpressions visualized in the context of the input XML document.This paper introduces XPlainer, a language that provides explanations of why XPath expressions return a specific answer. An explanation returns precisely the nodes in the input XML document that contribute to the answer. We provide a complete formalization for explanation queries based on the semantics of XPath. This enables the use of XPath engines for the evaluation of explanation queries.We describe a tool that uses XPlainer queries to provide visual explanations. The XPlainer-Eclipse tool is built on an extensible development environment that includes editors for visualizing both XML documents and XPath expressions as trees together with the explanation of the answers.
