You need to escape some of these characters in your data.

For & use &amp; instead.

For < and > use &lt; and &gt;

Inside attribute values, for " and ' use &quot; and &apos;
(you can quote them in other places too but it is not necessary)

For example,
    <activity whose="Susan's">R & D budget < 30000</activity>
might be quoted as
    <activity whose="Susan's">R &amp; D budget ^lt; 30000</activity>

You only need to quote " in attribute values if " was used for the
quotes and the same with ', like this
    <activity whose='Susan&apos;s'>....

You do not need to use a DTD for any of this.
