The POI project contains several components for dealing with popular OLE 2 formats in Java. POIFS is a pure Java implementation of the OLE 2 Compound document format. HSSF is a pure Java implementation of Excel 97-2003 XLS file format based on POIFS. HSSF Serializer is a pure Java serializer for Cocoon 2 that uses the Gnumeric XML format to output XLS. Full documentation of the POIFS file format is included. It is useful if you wish to output reports in the Excel file format, or if you have existing XML documents that you need to get into Excel. HSLF provides initial support for PowerPoint 97-2003 and HWPF provides limited support for Word 97-2003. POIFS can be used to read any OLE2 stream.
Youhp3 (Youpee's One Unlimited HTML PreProcessor) is an HTML preprocessor that allows you to embed code of any script language, as well as calling any external program to generate text files. It is specifically designed to work with HTML/XML documents, and provide traditional features, such as define, include, macro, conditional tests, and loop.
UWOBO is a XSLT stylesheet processor running as an HTTP server. In can be contacted with a proper URL which gives the URI of an XML document and a list of stylesheets to be applied. The processor will then apply the stylesheets in the given sequence, and will return the processed document as the result of the invocation.
The Styler Ant Task makes useful combinations of XSLT and other transformations easy to specify in an Ant build file. Styler can handle multiple transformations, in parallel or pipelined, split or merge files, process non-XML files such as HTML (based on JTidy), apply non-XSLT transformation, such as "regular fragmentations" and use any custom XMLReader or XMLFilter class to handle new file formats and transformation techniques.
SharedExpenses is a web-based expense manager. It's based on the idea of a group of people living in one house, needing to have common items purchased for both the house and individual members. It supports a number of useful features including group aliases, credits, receipts, and automatic expense dividing. It has been written in Perl using XML::Twig and CGI.
XMLPublication is a set of tools to generate Web pages from (possibly large) desktop documents or other structured documents, such as books with paragraphs, or tabular data. It cuts documents into Web pages, and creates customizable multi-indices. All this is done through a repeatable process in which data is separated from presentation and user settings. It uses XML techniques, particularly XSLT and Ant.
Qexo (Query Expressions for XML Objects aka Kawa-XQuery) is an implementation of W3C's draft XML query language XQuery. XQuery is a high-level expression language whose values are sequences of nodes (as in DOM) and simple values. It includes syntax for embedding XML or HTML results, and a 'for' statement comparable to SQL's 'select'. This implementation uses the Kawa tools to compile XQuery programs to Java bytecodes that can run on any JVM. XQuery programs can run as servlets, as standalone applications, or from the command-line.
