wx.lib.pubsub.utils.xmltopicdefnprovider

Contributed by Joshua R English, adapted by Oliver Schoenborn to be consistent with pubsub API.

An extension for pubsub (http://pubsub.sourceforge.net) so topic tree specification can be encoded in XML format rather than pubsub’s default Python nested class format.

To use:

xml = ‘’’

<topicdefntree> <description>Test showing topic hierarchy and inheritance</description> <topic id=”parent”>

<description>Parent with a parameter and subtopics</description> <listenerspec>

<arg id=”name” optional=”true”>given name</arg> <arg id=”lastname”>surname</arg>

</listenerspec>

<topic id=”child”>

<description>This is the first child</description> <listenerspec>

<arg id=”nick”>A nickname</arg>

</listenerspec>

</topic>

</topic> </topicdefntree>

‘’’

These topic definitions are loaded through an XmlTopicDefnProvider:

pub.addTopicDefnProvider( XmlTopicDefnProvider(xml) )

The XmlTopicDefnProvider also accepts a filename instead of XML string:

provider = XmlTopicDefnProvider(“path/to/XMLfile.xml”, TOPIC_TREE_FROM_FILE) pub.addTopicDefnProvider( provider )

Topics can be exported to an XML file using the exportTopicTreeSpecXml function. This will create a text file for the XML and return the string representation of the XML tree.
