#7624 closed defect (bug) (fixed)

Export blog feature produces invalid XML file

Reported by: rjwalsh Owned by:
Milestone: 2.7 Priority: high
Severity: major Version: 2.6.1
Component: Export Keywords: has-patch commit dev-feedback
Focuses: Cc:


The WXR output is not valid XML. Using minidom in Python (which uses Expat) to read the file can produce an error like this:

xml.parsers.expat.ExpatError: unbound prefix: line 90, column 0

Looking at the line in question, we see something like this:


The excerpt namespace is not defined. We need to add something like this to the rss attributes near the top of the file:


or some similar URL.

  • Priority changed from normal to high
  • Severity changed from normal to major
  • Version changed from 2.5.1 to 2.6.1

I can confirm that this also triggers errors in Firefox 3 and xml star, and prevents successful importation into Movable Type. I exported from WP 2.6 and 2.6.1.

As well as defining the namespace, A file needs to exist at the URL which describes the except namespace. Not something most people understand how to create..

DD32, only if you're using a validating parser. Quite rare.

The rest of the namespaces don't have files anyways.
