MATLAB: Please help me.. I want to import two data in string.

dataimportregexpstringworkspace

code is

————————————————————————————–

Str = [' <data seq="0"  <temp8.0</temp  <data seq="1"   <temp6.9</temp '];
Str(strfind(Str, '>')) = [];
Key_1   = '<temp';
Index_1 = strfind(Str, Key_1);
Value_1 = sscanf(Str(Index_1 + length(Key_1):end),'%f');

————————————————————————————–

In workspace, Value_1 = 8.0.

But I want to express Value_2 = 6.9

Use for… etc function

Finally,

In workspace,

I want to express

Value_1 = 8.0
Value_2 = 6.9
.

value_n = x.x

MATLAB: Extract 2 data(temperature) from string

Use regexp to match strings which

follow after the string "<temp"
consist of (digit,period,digit)
are followed by "</temp"

str = [' <data seq="0"  <temp8.0</temp  <data seq="1"   <temp6.9</temp '];
cac = regexp( str, '(?<=<temp)\d\.\d(?=</temp)', 'match' );
temp_2 = str2double(cac{2})
temp_1 = str2double(cac{1})

outputs

temp_2 =
    6.9000
temp_1 =
     8

Or use sscanf. The format_string is a copy of Str, in which the "numbers" you want to extract are replaced by the specifier, %f

num = sscanf( Str, '<data seq="0"  <temp%f</temp  <data seq="1"   <temp%f</temp' )

which outputs

num =
    8.0000
    6.9000

MATLAB: Extract numbers from mixed string.

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....
