xml api broken in 1.399?

[Brian J. Murrell]

Hi,

When I try to use the XML API to fetch some information about a
project's latest build (i.e.
http://jenkins/job/foo/lastSuccessfulBuild/api/xml?xpath=//artifact/displayPath&wrapper=top
I get an error:

Status Code: 500

Exception:
Stacktrace:
hudson.util.IOException2: Error on line 1 of document : Element type
"origin" must be followed by either attribute specifications, ">" or
"/>". Nested exception: Element type "origin" must be followed by either
attribute specifications, ">" or "/>".

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":[]}

The XML API was working up until recently. Is this something that has
broken recently?

Cheers,
b.

I've improved error diagnostics toward 1.401 so that we can see how
XML is broken in the error message.

Can you run it without the 'xpath' parameter and report back what
(broken) XML you get?

That was included in my original message...
