download xml text into struct

Hi there, I want to download data and save it in an struct file. Unfortunately my solution doesn't look clean: Data example: OSM Data

   function x = download(input)
    x = webread(strcat('https://www.openstreetmap.org/api/0.6/relation/', num2str(input)));
    fileID = fopen('temp.txt','w');
    fprintf(fileID,x);
    fclose(fileID);
    x = xml2struct('temp.txt');
    delete temp.txt

Is there a way without creating and deleting an text file?

Edit: After i had some other Problems with using xml, i decided i wont consider this solution anymore. I am now working with strfind() instead.

What's xml2struct? Not ML function...
