Extensible HTML/XML generator
XIST is an extensible HTML and XML generator. XIST is also a XML parser 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 XSLT’.
XIST also includes the following modules:
- ll.astyle can be used for colored terminal output (via ANSI escape sequences).
- ll.color provides classes and functions for handling RGB color values. This includes the ability to convert between different color models (RGB, HSV, HLS) as well as to and from CSS format, and several functions for modifying and mixing colors.
- ll.make is an object oriented make replacement. Like make it allows you to specify dependencies between files and actions to be executed when files don’t exist or are out of date with respect to one of their sources. But unlike make you can do this in a object oriented way and targets are not only limited to files, but you can implement e.g. dependencies on database records.
- ll.misc provides several small utility functions and classes.
- ll.sisyphus provides classes for running Python scripts as cron jobs.
- ll.daemon can be used on UNIX to fork a daemon process.
- ll.url provides classes for parsing and constructing RFC 2396 compliant URLs.
- ll.xpit is a module that makes it possible to embed Python expressions in text (as XML style processing instructions).
- ll.xml_codec contains a complete codec for encoding and decoding XML.
Changes in 3.2.4 (released 04/02/2008)
The following functions have been added to ll.xist.css: parsestring, parsestream, parsefile, parseurl and write. They parse CSS resources and are similar to the XML/HTML parsing function in that they apply the specified base URL to all URLs in the style sheet.
cssutils 0.9.5b2 is required now.
ll.xist.css.iterrules and ll.xist.css.applystylesheets now support specifying whether the preferred stylesheets or an alternate stylesheet group should be used.
ll.xist.xsc.ProcInst.__mul__ and ll.xist.xsc.ProcInst.__rmul__ now return a fragment containing the node repeated a number of times instead of one processing instruction node containing repeated content.
The constructor for ll.xist.parsers.ExpatParser now takes two additional arguments:
If this is true the XML declaration will appear in the resulting XIST tree.
If this is true the doctype declaration will appear in the resulting XIST tree (however any interal DTD subset will be dropped).
