Either

<a
  ><b
     ><c>C</c
     ></b
  ></a
>

or (ugh)

<a
  ><b
     ><c>C</c></b></a>

or any number of other variations. These don't add white space. Careful
about the whitespace rules in XML you cannot break up "<a" or "</a".

If you have a DTD and i) you define it correctly; and ii) I remember
correctly, then this:

<a>
  <b>
    <c>C</c>
  </b>
</a>

does not introduce white space unless <a> and <b> are defined to have mixed
content.
