optimization suggestion for results words (lower case)

[leonardo0014]

Hi I think the program is great and I have a suggestion for improvement. For lack of rights/knowledge I can only post it as an issue.

I have reports here, for example, they write "pass" and in others they write "Pass". In the output, this is then interpreted as 2 different values. The results from the XML files such as "unknown", "temperror", "softfail", "pass" and so on should be converted to lower case by the parser.

That was it. Thank you and keep it up!
