AppleScript click on Safari  link
Don't use getElementById. Its a pain in the a** and almost never works for what you want.  Additionally none of your elements actually have id's so theres no point in use it. Instead use JavaScripts beautiful and helpful querySelector.  You can use CSS selectors to selector a single element and do what ever you want from there.

The element you are trying to select has a unique data attribute. The data attribute is data-auto-test-id= and the content of that attribute is ViewTrustedMachines so we can select it simply with document.querySelector('a[data-auto-test-id="ViewTrustedMachines"]'). Finally we just add the .click() to...well...click it.

tell application "Safari"
   do JavaScript "document.querySelector('a[data-auto-test-id=\"ViewTrustedMachines\"]').click();"
end tell


Also correct your HTML:

&lt;table&gt;


    &lt;tbody&gt;
        &lt;tr&gt;
            &lt;th&gt;Geo&lt;/th&gt;
            &lt;td&gt;USA&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;th&gt;Download Queue&lt;/th&gt;
            &lt;td&gt;0&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;th&gt;Wish List&lt;/th&gt;
            &lt;td&gt;0&lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
            &lt;th&gt;Something else&lt;/th&gt;
            &lt;td&gt;
                &lt;a data-auto-test-id="ViewSomethingelse" href="/WebObjects/support.woa/wo/iKK52GLbH8yXxkrGGvN4M/4.4.5.15.1.7.0.142.0.0.1"&gt;View&lt;/a&gt;
            &lt;/td&gt;
        &lt;/tr&gt;

        &lt;tr&gt;
            &lt;th&gt;Trusted Machines&lt;/th&gt;
            &lt;td&gt;
                &lt;a data-auto-test-id="ViewTrustedMachines" href="/WebObjects/support.woa/wo/iKK52GLbH8yXxkrGGvN4M/4.4.5.53.7.5.0.447.0.0.1"&gt;View&lt;/a&gt;
            &lt;/td&gt;
        &lt;/tr&gt;
        &lt;/tbody&gt;
        &lt;/table&gt;


Finally, here's a fiddle to show it in action.
