Genshi is a template engine for XML-based vocabularies written in Python. Genshi is used to easily insert generated output into XML-based languages, usually HTML, and reuse elements between documents. Genshi is based on Kid and aims to implement some of its functionality while processing templates faster.[1]

Genshi can be used with several Python web frameworks, such as CherryPy,[2][3] TurboGears,[4] Pylons[5] and web2py.[6] Genshi has replaced Kid in the TurboGears 2.x web framework.[7]

Genshi markup[edit]

Genshi makes use of namespaces to embed instructions into HTML. A typical instruction is given as an attribute, with a Python expression inside the quotes. For example, the following will render a paragraph that shows 4:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:py="http://genshi.edgewall.org/">
    <body>
        <p py:content="2 + 2">This will be replaced with 4</p>
    </body>
</html>

Because of the use of namespaces, Genshi can be used in WYSIWYG HTML editors.[8][9]

Differences between Kid and Genshi[edit]

  • Genshi directly interprets templates (unlike Kid, which generates Python code)[10]
  • Genshi uses XInclude for template reuse[10]
  • Genshi adds attributes Kid does not have, like py:choose[10]
