Filter by content type?

Um, vocabs are assigned to content types through the taxonomy admin page.
A vocab applies to one or more content type. You then choose the vocab to export.
Not sure what can be done there.

To do more would mean filtering by nodes that are in use or something, I don't know what that would look like. Sounds a bit advanced.

Hi Sinan,

The following is an excerpt from the sample.xml that comes with the module:

<?xml version="1.0" standalone="no"?>
<!DOCTYPE taxonomy SYSTEM "taxonomy.dtd">
<vocabulary>
  <vid>5</vid>
  <name>Editorial sections</name>
  <description/>
  <help/>
  <relations>0</relations>
  <hierarchy>1</hierarchy>
  <multiple>0</multiple>
  <required>0</required>

  <nodes>blog,page,story</nodes>

  <weight>0</weight>
  <term>
    <tid>83</tid>
    <vid>5</vid>
    <name>Analysis</name>
    <description>Examines the connections between known facts.</description>
    <weight>0</weight>
    <depth>0</depth>
    <parent>0</parent>
  </term>
   ...
</vocabulary>

You see that the nodes the vocabulary applies to are registered in the aptly named tag "nodes". So at least you could filter your terms after exporting, using XSLT for example.

That's for the old Drupal-only-XML format.
The RDF format tagged here does not insert platform-specific data like that. At least it won't unless there are good standards-compliant ways to notate something like that.
