The Gnome DOM Engine

Paolo Casarini, Luca Padovani


The widespread use of Web technologies and, in particular, the ever growing number of applications adopting XML as the standard language for the encoding of any piece of structured information, naturally calls for efficient implementations of DOM, the standard interface to access the internal structure of documents. The DOM level 2 API, which has been conceived as a suitable hierarchy of classes, has its most natural mapping in object-oriented languages such as C++ and Java. This is also testified by the already existing implementations in those languages. However, as of today, most applications are commonly developed in C, because of its standardization, flexibility, efficiency and availability. In this paper we describe the current state of Gdome2, which provides a DOM implementation for the C programming language. The library is meant to become a key module of the Gnome architecture, supplying a range of facilities for an efficient, portable, and easy management of XML documents in the Gnome way. We conclude with a comparison between Gdome2 and Xerces, one of the more advanced and actively developed DOM implementations.
