LEESA: A new way of typed XML programming in C++

Some of my recent research work has focused on developing a highly generic and reusable library for complex object structure traversal, which is best exemplified by schema driven XML programming. I'm glad to present a research paper called LEESA: Embedding Strategic and XPath-like Object Structure Traversals in C++, which will be published in the proceedings of IFIP Working Conference on Domain Specific Languages (DSL WC), 2009 at Oxford, UK. LEESA stands for Language for Embedded quEry and traverSAl. LEESA has advanced the state-of-the-art of the typed XML programming in standard C++ to a level where many benefits of static type analysis can be maintained while enjoying a succinct syntax similar to that of XPath. Below, a quick motivating example of LEESA that sorts and prints the names of the authors in a XML book catalog is shown.

Catalog() >> Book() >> Author() >> Sort(Author(), LastNameComparator) >> ForEach(Author(), print);

The key thing to be noted he…
