The Butterfly XML Editor and IDE is an XML editing environment built on top of a real-time incremental XML parsing algorithm. It features syntax and error highlighting, incremental validation, intelligent code completion (based on XML Schema, DTD, or document analysis), XSLT Debugging, XSLT pipelines, Docbook Rendering, XSL:FO Rendering, and side-by-side DOM and source viewing. Built-in support for Docbook, XSL:FO, XHTML, XSL, Xforms, XML Schemas, XSP, and Cocoon sitemaps is included. Support for other XML types can also easily be added. It is capable of parsing documents that are not well-formed, and shows the source of the errors, allowing for the easy conversion of HTML to well-formed XML. XSLT pipelines simplify the process of building up and visualizing complex transformations.
NekoHTML is a simple HTML scanner and tag balancer that enables Java application programmers to parse HTML documents and access the information using standard XML interfaces. The parser can scan HTML files and "fix up" many common mistakes that human (and computer) authors make in writing HTML documents. NekoHTML is written using the Xerces Native Interface (XNI) that is the foundation of the Xerces2 implementation. This enables application programmers to use the NekoHTML parser with existing XNI tools without modification or rewriting code.
NekoStyle is a simple and flexible framework for automating XML transformations. With NekoStyle, you can parse XML and HTML documents, perform XSLT transformations, output documents in different formats, and much more. An Ant build task is also included to allow batch XML processing to be run during a build.
NekoXNI is a collection of small, useful XML tools written for the Xerces Native Interface (XNI) that is the foundation of the Xerces2 implementation. The NekoXNI tools are written to illustrate the power and flexibility of the XNI framework, as well as provide useful tools for XML application developers. The current collection of XNI tools includes an HTML Parser, DTD Converter, a Style Processor, a RelaxNG Validator parser configuration, and an XML Pull Parser.
