Function that has a text file as input

Hi I somehow know how to create a new function in matlab, while the function has NUMBERS as input. How can I define a Text file as input for my Matlab function? your answers really makes my life easier.

What exactly do you mean by "text file"? The name or the contents of the file?

Both possibilities mean, that the input is a string, but in the first case, the input is treated as file name.

I will explain more,

I have a script , that I used the function fopen and text scan to open and read a text file. then i used the numbers inside the text file and created a XML file.

Now I want to do something like this

function xmlFilename=rob2xml(name of text file)

fid=fopen(text file)

textscan

fclose

some mathematical experesion

xmlFilename=[tempname,'.xml']

but it does not work

What did you do exactly and what does "it does not work" mean explicitely? Currently the description of the problems is too vague to allow a specific answer.
