Publish JUnit test result report containing multiple testsuites

[CB]

I have cxxtest unit tests publishing JUnit-like output using a custom 
XmlPrinter.  A few test files contain multiple testsuites, causing an xml 
output with multiple <testsuite> elements, example;

<?xml version="1.0" encoding="UTF-8" ?>
    <testsuite name="FooTest" file="CombinedTest.h" line="20">
        <testcase name="testCtor1" line="25">
        </testcase>
        <!-- snip -->
    </testsuite>
    <testsuite name="BarTest" file="CombinedTest.h" line="390">
        <testcase name="testCtor1" line="395">
        </testcase>
        <!-- snip -->
    </testsuite>

However, Jenkins Junit publisher chokes on these files, with 

Caused by: 
org.dom4j.DocumentException<http://stacktrace.jenkins-ci.org/search?query=org.dom4j.DocumentException>:

Is there an easy way around this without restructuring my test files?
