I don't understand what this patch is attempting to fix, or how it does so. Best I can tell, it will do nothing.

After line 329, rawXML contains the first 500 characters in path, or the entire contents of the file, whichever is smaller.

The only thing the .Trim() will do is remove leading and trailing whitespace for the subsequent <api>/<package check (line 331) or package/; check (lines 333-334).

I fail to see how the .Trim() will change the behavior.

Now I do: https://github.com/xamarin/xamarin-android/pull/982/files#diff-32de99b7f2c580b2994a04fa8f2e1948R1
