Therefore it provides a full featured tag library to define all properties of the chart (colors, strokes, legend, etc.). Thus the JSP which embedds the chart is not polluted with any java code. Everything is described with XML conform tags.

The output files produced by LaTeX2e and DocBook can in turn be used to produce PDF, text, HTML, PostScript, and more.

Java 在 XML API 上也有很好的支援，除了有來自標準規範、神奇的傑克家族(JAXP、JAXB、JAXR...)可用，Third Party 廠商在這方面的支援也是不遑多讓，如 Jdom, Dom4j...

XML Processing API:

• JDom
• XOM: Here is a introduction of XOM.
• JRom from IBM: means Java Record Object Model
• XMLPull API
  • Home page of XML Pull Parser (XPP): Xml Pull Parser (in short XPP) is a streaming pull XML parser and should be used when there is a need to process quickly and efficiently all input elements (for example in SOAP processors). Pull parsing is just one level up from tokenizing XML (and that is actually how XPP2 default implementation is done). This means that XPP is representing the simplest way of processing XML that you can get (working with tokenizer would be even lower level but is not simple and most of applications would be much more complex to extract useful information from XML tokens ...). With XPP pull parser it is easy to build a next layer on top of it such as standard SAX2 push model (a prototype SAX2 driver for XPP2 is available). Every SAX2 parser has a tokenizer and a pull interface buried inside and XPP2 exposes this layer allowing for faster XML processing - and that is what I wanted to achieve in XPP2 and what makes this project interesting :-)
  • XML Pull Parsing Common API: It is a minimalist API: very easy to implement standalone or on top of existing parser. The API allows both fast high level iteration (using next() method) and low level tokenizing (using nextToken() token) and is designed for easy building on top of it SAX, XML pull parsers that uses iterators with event objects, or even DOM implementations. To to support J2ME and real small implementation parsing of DOCDECL is optional (but DOCDECL can be reported if requested).
  • kObjects.org: kXML 2: "kXML 2 is a small XML pull parser, specially designed for constrained environments such as Applets, Personal Java or MIDP devices. In contrast to kXML 1, kXML 2 is based on the common XML pull API"
• Apache Xalan: XPath & XSLT Processor
• Apache XTags: Base on Dom4j
• JAXP from Sun: Java XML Pack, 內建W3C XML Schema Language支援, 包括:
  • Java API for XML Processing (JAXP)
  • Java API for XML Messaging (JAXM)
  • Java API for XML Registries (JAXR)
