How do I use genshi.builder to programmatically build an HTML document? | 112,564 | <p>I recently discovered the genshi.builder module. It reminds me of Divmod Nevow's Stan module. How would one use genshi.builder.tag to build an HTML document with a particular doctype? Or is this even a good thing to do? If not, what is the <em>right</em> way?</p>
| 3 | 2008-09-21T23:37:58Z | 112,659 | <p>Genshi.builder is for "programmatically generating markup streams"[1]. I believe the purpose of it is as a backend for the templating language. You're probably looking for the templating language for generating a whole page.</p>

| 3 | 2008-09-21T23:37:58Z | 112,860 | <p>It's not possible to build an entire page using just <code>genshi.builder.tag</code> -- you would need to perform some surgery on the resulting stream to insert the doctype. Besides, the resulting code would look horrific. The recommended way to use Genshi is to use a separate template file, generate a stream from i... | 4 | 2008-09-22T02:12:07Z | [
