Extract and plot from .txt file

Hi! I want to build a script that is able to extract points from a .txt file and do a 3D plot. The text file looks like this:

Element            Real         Nominal        Desviac.       Tol. sup.       Tol. inf.      Dent./Fue.
                                                       (Desv TP)        (Tol TP)                                
Point: Point-2[1,1](ID:1, from 1 point) 
     Coord. X =       183,250100                                                                                
     Coord. Y =       253,308300                                                                                
     Coord. Z =        25,185977                                                                                

Point: Point -2[1,2](ID:2, from 1 point) 
     Coord. X =       183,250200                                                                                
     Coord. Y =       251,308200                                                                                
     Coord. Z =        25,177848                                                                                

NOT VALID ELEMENT: POINT-2[1,4](ID:3, from 1 point) 
         ****  
         ****  
         ****  
Point: Point -2[1,3](ID:4, from 1 point) 
     Coord. X =       183,250200                                                                                
     Coord. Y =       249,308200                                                                                
     Coord. Z =        25,171169  
...

I tried different ways but my code is not working. How can I do it?

Thank you in advance!

fid = fopen('sample.txt'); % name of your text file
f = textscan(fid,'%s','delimiter','\n');
fclose(fid);
z = f{:};
Z=regexprep(z(contains(z,'=')),',','.'); % interpreting comma as dot
func = @(x) regexp(x,'\d+[\.?]\d*','match','once');
Datas = reshape(str2double(cellfun(func,Z,'un',0)),3,[]); % 3 represents x,y,z so three rows
plot3(Datas(1,:),Datas(2,:),Datas(3,:))
