How to convert Selenese (html) to Python programmatically?

How would I convert test cases made by Selenium IDE to Python without exporting every test case by hand? Is there any command line converter for that job?

In the end I want to use Selenium RC and Pythons build in unittest to test my websites.

Thanks a lot.

Update:

I started to write a converter but its too much work to implement all the commands. Is there any better way?

from xml.dom.minidom import parse

class SeleneseParser:

        self.dom = parse(selFile)

    def getBaseUrl(self):
        return self.dom.getElementsByTagName('link')[0].getAttribute('href')

    def getNodes(self):
        cmds = []
        nodes = self.dom.getElementsByTagName('tbody')[0].childNodes

        for node in nodes:
            if node.nodeType == node.TEXT_NODE and "\n" in node.data:
                continue
            if node.nodeType == node.COMMENT_NODE:
                cmds.append(node.data)
            if node.nodeType == node.ELEMENT_NODE:
                cmd = []
                for c in node.childNodes:
                    if c.nodeType == node.ELEMENT_NODE:
                        if len(c.childNodes) == 1:
                            cmd.append(c.childNodes[0].data)
                        else:

I've started building a Selenese-to-Python parser, PySelenese, which I've posted on Github. Feel free to fork/clone the repository and give it a try: http://github.com/jpstacey/PySelenese .

No there isn't a way but in theory it shouldn't be too difficult to do as all you need to do is have something that uses the python-rc.js to convert the file.
