Since the UUID data in this case is returned as an ElementTree instance, Since the UUID data in this case is returned as an ElementTree instance,
one can use ElementTree from the standard library to access the data. one might first turn to ElementTree from the standard library. There's
For example, to extract the **CreatorTool** attribute value, the following a better solution though, particularly if you need to create XMP, and that
would work:: is to Use the Python XMP Toolkit instead (make sure you use version 2.0 and
not 1.0.2).::
>>> xmp = j.box[3].data.packet
>>> rdf = '{http://www.w3.org/1999/02/22-rdf-syntax-ns#}'
>>> ns2 = '{http://ns.adobe.com/xap/1.0/}'
>>> name = '{0}RDF/{0}Description/{1}CreatorTool'.format(rdf, ns2)
>>> elt = xmp.find(name)
>>> elt
<Element '{http://ns.adobe.com/xap/1.0/#}CreatorTool' at 0xb50684a4>
>>> elt.text
'Google'
Yes, that's painful. A better solution is to install the Python XMP Toolkit
(developer branch)::
>>> from libxmp import XMPMeta >>> from libxmp import XMPMeta
>>> from libxmp.consts import XMP_NS_XMP as NS_XAP >>> from libxmp.consts import XMP_NS_XMP as NS_XAP
