Filtering XML content for publication and presentation on the web

In this paper we describe a tool for imposing constraints in the content of webpages. This tool can be used in one of two ways, by imposing constraints on content previously to its dissemination on a website or by imposing constraints on content which is being presented to users inside a local area network. The tool allows the composition of constraints either visually or manually for removing, replacing or even blocking content from publication and presentation. This tool relies on a highly declarative and flexible approach enabling an agile implementation of constraints.
