Staroffice/Openoffice to HTML Converter converts a Staroffice/Openoffice.org document to HTML, using xsltproc for the XML conversion and ImageMagick's convert to convert images. It creates a table of contents with links, and handles tables, styles, spans, and many other XML elements from a writer file.
The GCC XML Tree Node Introspector project consists of a patch to the gcc compiler to output the internal compiler tree nodes in RDF/XML and programs to process that RDF/XML. The tree nodes are complex data structures which represent the source code inside the compiler. Through these tree nodes, users are able to extract information from their programs that would be otherwise very difficult to obtain. Modules exist to store these nodes in Redland RDF using a Berkley database. The long-term goal of the project is create a high-level API that will make the programmatic manipulation of programs easier than it is now.
The XCB library provides an interface to the X Window System protocol, designed to replace the Xlib interface. It has several advantages over Xlib, including size (small library and lower memory footprint), latency hiding (batch several requests and wait for the replies later), direct protocol access (one-to-one mapping between interface and protocol), thread support (access XCB from multiple threads, with no explicit locking), and easy creation of new extensions (automatically generates its interface from machine-parsable XML protocol descriptions). Xlib can also use XCB as a transport layer, allowing software to make requests and receive responses with both, which eases porting to XCB. However, client programs, libraries, and toolkits will gain the most benefit from a native XCB port.
xcb-proto contains descriptions of the X Window System core protocol and selected extensions in an XML-based data format. They are used by the X C Binding (XCB) library to generate much of its code, but you can also use these descriptions for other purposes, such as decoding the X protocol or building X Window System bindings for other languages.
