Read datas with different extension in a loop

Hi i wrote code to read text files and it works properly.The Problem is from test device i get results with different ending. sometimes with '.*erg' sometimes another Option.I think that i should write a function and Combine with Loop. Could you recommend me something ? Thanks

I want to add this Kind of thing to read my files dynamically which have different extension.

clear all 
clc
function einlesen= ergebnisfiles(i)
if ergebnisfiles(i)=dir('*.erg')
    daten=fopen('ergebnisfiles(i)','r')
zeile = textscan(daten,formatSpec1,181,'delimiter',';','headerLines',4)
fclose(daten);
else if ergebnisfiles(i)=dir('*txt')
daten=fopen('ergebnisfiles(i)','r')
zeile = textscan(daten,formatSpec1,181,'delimiter',';','headerLines',4)
fclose(daten);
    else ergebnisfiles(i)=dir('*pdf')
daten=fopen('ergebnisfiles(i)','r')
zeile = textscan(daten,formatSpec1,181,'delimiter',';','headerLines',4)
fclose(daten);
    end
end
end

Please format your code correctly to make it readable. You can edit the original question instead of hiding important information in a comment, where it vanishes as soon as some other comments are posted.

Omit the "clear all" to allow the usage of the debugger.

I do not understand the connection between your question and the code. But a comment:

for i=1:length(zeile{1,1})
  tmp=zeile{1,1}{i}
  tmp=strrep(tmp,'.','_dot')
  zeile{1,1}(i)=cellstr(tmp);
end

Smarter without a loop:

zeile{1} = strrep(zeile{1}, '.', '_dot');

   function einlesen= ergebnisfiles(i)
ergebnisfiles={};
if ergebnisfiles(i)=dir('*.erg')
    daten=fopen('ergebnisfiles(i)','r')
einlesen = textscan(daten,formatSpec1,181,'delimiter',';','headerLines',4)
fclose(daten);
else if ergebnisfiles(i)=dir('*.txt')
daten=fopen('ergebnisfiles(i)','r')
zeile = textscan(daten,formatSpec1,181,'delimiter',';','headerLines',4)
fclose(daten);
    else ergebnisfiles(i)=dir('*.pdf')
daten=fopen('ergebnisfiles(i)','r')
zeile = textscan(daten,formatSpec1,181,'delimiter',';','headerLines',4)
fclose(daten);
    end
end
end
