- <title>Pre-release of PXP, the XML parser for O'Caml</title>
-
- <p>PXP is the new, completely revised and partly rewritten
-validating XML parser
-for O'Caml; the old name, "Markup", has been dropped. The current version
-of PXP is still a bit experimental because it is not fully tested; however,
-it is now stable enough to be used in experimental applications.
-</p>
-
- <p>PXP will retain most parts of Markup's API; the name PXP
-emphasizes the strengths of the API: it is the Polymorphic XML Parser.
-The document objects representing the parsed file have an interesting
-polymorphism which allows that the user of the parser can control
-which kind of objects are actually created. The current API supports
-the element type as criterion for object/class selection; future APIs will
-extend this concept such that arbitrary criterions are possible
-(e.g. you may want to have different classes for different namespaces).
-</p>
-
- <p>The current development goals of PXP are:</p>
-
- <ul>
- <li><p><em>Full XML-1.0 conformance:</em> The current pre-release
-is now very close to strict XML-1.0 conformance. The only bigger
-difference to the standard is that PXP sometimes accepts DTDs as legal
-while the standard forbids them (non-deterministic content models).</p>
-
-<p>One of the more important improvements since 0.2.10 is the possibility to
-represent XML documents internally as UTF-8 strings, not only as ISO-8859-1
-strings. Thanks to Claudio Sacerdoti Coen who contributed a special lexer
-preprocessor hiding the details of the UTF-8 encoding in the lexer definitions.
-</p>
- </li>
-
- <li><p><em>Correctness of validation:</em> The well-formedness
-and valididity constraints must be implemented as correct as possible.
-The last stable release had already a regression test covering many
-aspects of XML. The test suite will be extended.</p>
- </li>
-
- <li><p><em>Parsing performance:</em> It should be possible to
-process large amounts of data in a reasoable period of time. The last
-stable release had many stages of processing that wasted time.</p>
-
- <p>The current pre-release is already 30 per cent faster than
-0.2.10.</p>
- </li>
-
- <li><p><em>Simplicity of usage:</em> Unlike parsers basing on
-imperative languages and DOM, the usage of PXP should be simple, even
-for complex tasks. The current parser API has already many advantages
-over DOM; especially it is well integrated into the functional and
-object-oriented language O'Caml. You do not have to deal with
-artificial representations like "node lists" while the programming
-environment already provides good support for list structures. The
-fact that O'Caml allows a functional programming style is interesting
-for programs transforming XML trees.</p>
- </li>
- </ul>

- <title>Download the PXP pre-release</title>
-
- <p>The current pre-release is available under
-<a href="&url.gps-ocaml-download;/pxp-pre-0.99.8.tar.gz">
-&url.gps-ocaml-download;/pxp-pre-0.99.8.tar.gz</a>. There is currently no
-documentation for this version of the software; it is recommended to use the <a
-href="&url.markup-manual;">Markup manual</a> and compare it with the current
-module interfaces.</p>
-
- <p>Please note that this is work in progress; it may still contain bugs
-and irregularities.</p>
-
- <p>The parser works only with OCaml-3. The parser needs the <a
-href="&url.netstring-project;">netstring package</a>, at least version 0.9.1.
-</p>
-
- <p>I am very interested in your opinion to PXP; please <a
