Description
As was reported in the thread http://groups.google.com/group/jenkinsci-users/browse_thread/thread/1f269f9ccad08fd9# the XML API is broken as of 1.399ish:
When I try to use the XML API to fetch some information about aproject's latest build i.e.http://jenkins/job/foo/lastSuccessfulBuild/api/xml?xpath=//artifact/displayPath&wrapper=top I get an error:

If I try to use a more basic URL: http://jenkins/job/foo/lastSuccessfulBuild/api/xml I get:
This page contains the following errors: error on line 1 at column 162: error parsing attribute name Below is a rendering of the page up to the first error. Started by an SCM change
yet the JSON and Python APIs for the same URL work just fine: http://jenkins/job/foo/lastSuccessfulBuild/api/xml
{"actions":[{"causes":[{"shortDescription":"Started by an SCM
change"}]},{},{"buildsByBranchName":{"...":
...
,"changeSet":{"items":[],"kind":null},"culprits":[]}

added a comment - Brian, there is no 'displayPath' element below 'artifact' in your example. So the xml API is IMO working correct.
Probably this is some Matrix project specific thing that displayPath is not rendered.
Are you sure that matrix projects used to render it?

added a comment - kutzi,
Yes, it works with matrix jobs and in fact will work with a different axis value on the same job as it fails with a different axis value! But first I have to confess that to keep the examples simple, in my examples above, I reduced the number of matrix values. So to further illustrate:
Yields artifacts, yet:
does not. And yes, when I look at the XML from those two URLs (without the xpath), indeed, one job has it's artifacts section looking like:
<artifact>
<displayPath>filelists.xml.gz
</displayPath>
<fileName>filelists.xml.gz
</fileName>
<relativePath>artifacts/repodata/filelists.xml.gz
</relativePath>
</artifact>
<artifact>
and the other is simply:
<artifact>
<fileName>filelists.xml.gz
</fileName>
<relativePath>artifacts/repodata/filelists.xml.gz
</relativePath>
</artifact>
But these are two jobs from the exact same matrix job!
In any case, I seem to be able to work around the problem by using an xpath of fileName instead of displayPath.

added a comment - I guess that's an issue with matrix jobs in general, that the displayPath is not generated for all matrix values.
Please open a bug report against the matrix component, if this is an issue for you.

Log:
JENKINS-8988 picking up new Stapler that fies the XML API issue.
We are at 1.423 now and this issue is still reproducible. From the URL:
http://jenkins/job/foo/arch=x86_64,distro=el5/lastSuccessfulBuild/api/xml?xpath=//artifact/displayPath&wrapper=top
all I get is:
However from
http://jenkins/job/foo/arch=x86_64,distro=el5/lastSuccessfulBuild/api/xml
I get the job's full XML output:
