09f869a98149 Add reStructuredText documentation files. cmlenz parents: diff changeset	65 One important feature of markup streams is that you can apply filters to the
230 24757b771651 Renamed Markup to Genshi in repository. cmlenz parents: 226 diff changeset	66 stream, either filters that come with Genshi, or your own custom filters.

09f869a98149 Add reStructuredText documentation files. cmlenz parents: diff changeset	68 A filter is simply a callable that accepts the stream as parameter, and returns
508 cabd80e75dad Enable syntax highlighting (with Pygments) on doc page. cmlenz parents: 438 diff changeset	69 the filtered stream:

09f869a98149 Add reStructuredText documentation files. cmlenz parents: diff changeset	78 Filters can be applied in a number of ways. The simplest is to just call the

09f869a98149 Add reStructuredText documentation files. cmlenz parents: diff changeset	85 The ``Stream`` class also provides a ``filter()`` method, which takes an
508 cabd80e75dad Enable syntax highlighting (with Pygments) on doc page. cmlenz parents: 438 diff changeset	86 arbitrary number of filter callables and applies them all:

508 cabd80e75dad Enable syntax highlighting (with Pygments) on doc page. cmlenz parents: 438 diff changeset	93 which allows a syntax similar to pipes on Unix shells:

230 24757b771651 Renamed Markup to Genshi in repository. cmlenz parents: 226 diff changeset	99 One example of a filter included with Genshi is the ``HTMLSanitizer`` in
24757b771651 Renamed Markup to Genshi in repository. cmlenz parents: 226 diff changeset	100 ``genshi.filters``. It processes a stream of HTML markup, and strips out any

438 6fd7e4dc0318 Added documentation page on the builtin stream filters. cmlenz parents: 394 diff changeset	131 Serialization means producing some kind of textual output from a stream of

6fd7e4dc0318 Added documentation page on the builtin stream filters. cmlenz parents: 394 diff changeset	135 The ``Stream`` class provides two methods for serialization: ``serialize()`` and
6fd7e4dc0318 Added documentation page on the builtin stream filters. cmlenz parents: 394 diff changeset	136 ``render()``. The former is a generator that yields chunks of ``Markup`` objects
