XIST 2.6 has been released!


What is it?
===========

XIST is an extensible HTML/XML generator written in Python. XIST is
also a DOM parser (built on top of SAX2) with a very simple and
Pythonesque tree API. Every XML element type corresponds to a Python
class, and these Python classes provide a conversion method to transform
the XML tree (e.g. into HTML). XIST can be considered "object oriented XSL".


What's new in version 2.6?
==========================

  * A new API named XFind has been added for iterating through XML
     trees. XFind expressions look somewhat like XPath expressions but
     are pure Python expressions. For example finding all images inside
     links in an HTML page can be done like this:

         from ll.xist import parsers
         from ll.xist.ns import html
         node = parsers.parseURL("http://www.python.org/", tidy=True)
         for img in node//html.a/html.img:
            print img["src"]

  * ToNode now tries iterating through the value passed in, so it's
     now possible to pass iterators and generators (and generator
     expressions in Python 2.4) to Frag and Element constructors.

  * Parsing broken HTML is now done with the HTML parser from libxml2.

  * The parser now has the option to ignore illegal elements,
     attributes, processing instructions and entities.

  * A new class ll.xist.xsc.NSPool has been added. An NSPool contains
     a pool of namespaces from which the parser selects the appropriate
     namespace once an xmlns attribute is encountered.

   * Other minor changes and updates.
