Strange behaviour of ET under TG

Description (last modified by mgood)

Seeing strange behaviour with ET under TurboGears trunk (2216):

Here's the traceback:

    tag_name = QName(element.tag.lstrip('{'))
AttributeError: 'Stream' object has no attribute 'tag'

This has been around for a while. I assume it's peculiar to my setup otherwise someone else would have reported it. I have a workaround which is to switch the ET for XML: 

<head profile="http://www.w3.org/2003/g/data-view"  py:match="head" py:attrs="select('@*')">
    <title py:replace="''">Your title goes here</title>
    <link py:for="js in tg_js_head" py:replace="XML(js.display())" />
    <link py:for="css in tg_css" py:replace="ET(css.display())" />
    <meta py:replace="select('*')" />
</head>

The problem doesn't seem to be related to the profile attribute in that it persists even when the profile attribute-value pair is removed.

AttributeError?: 'Stream' object has no attribute 'tag'

Same workaround fixes the problem.

Last piece of info:

Genshi settings in TG's project/config/app.cfg are:

genshi.outputformat = "xml"

genshi.assume_encoding="utf-8"

genshi.encoding="utf-8"

  • Cc needinfo added
  • Description modified (diff)

What happens if you just use js.display() and css.display() without using the ET() method? It sounds like you're passing a Genshi Stream object to the ET method instead of an ElementTree element. If that's the case then you don't need to wrap it with either the XML or ET calls.

comment:6 Changed 18 years ago by cmlenz

  • Resolution set to worksforme
  • Status changed from new to closed

Closing due to lack of information, which would be required to find out whether the problem is in Genshi.
