Unexpected '<' in attribute value at [row,col {unknown-source}]

[Manpreet Singh]

Hi All

I have integrated Robot Framework with Jenkins 1.651.2 and running 3 simple tests in parallel om Chrome and Firefox. The tests run but while publishing the test results, no stats are appearing. While checking the Console Output log, I have found the following error, 

Output:  C:\ArriveAutomation\Output\output.xml
[ ERROR ] Reading XML source 'C:\ArriveAutomation\Output\output.xml' failed: ParseError: not well-formed (invalid token): line 152, column 207

Try --help for usage information.
Build step 'Execute Windows batch command' marked build as failure
Robot results publisher started...
-Parsing output xml:
Failed!
java.io.IOException: Parsing of output xml failed!

The same tests run fine if run in a sequential manner. Has anybody faced this issue? Please help me to fix this issue.

Thanks in advance...
