How to get the 2nd head line in the chart generated by the Tester ?

 
After testing an EA, let's click the button "Open Chart" in the Tester window.
For this chart, using a script, how to get the second string line in top-left of this chart.
The line with the EA's filename.
This line is not a text object, so it's not in the list object.

EXAMPLE OF THIS 2ND LINE:
EMA_CROSS testing with ....

Thanks
