There are probably better ways to do this but if this is always going to be the string and only the numbers are going to change, you can use strfind() to get the locations of "temp"
Something like this:
xStr = strfind(Str, 'temp');
temp_1 = str2double(Str(xStr(1)+4:xStr(1)+6));
You should then be able to figure out temp_2....

Use regexp to match strings consisting of (digit,period,digit), and which follow after the string "temp"
Str = ['<data seq="0"<temp8.0</temp<data seq="1"<temp6.9</temp'];
cac = regexp( Str, '(?<=temp)\d\.\d', 'match' );
temp_2 = str2double(cac{2});
temp_1 = str2double(cac{1});
