Tips for Valid XHTML Snippets for External Tracking

A few tips for valid XHTML code:

  1. Each element must be a single element. For example, the following code will not validate:

    <script>...</script>
    <script>...</script>

    In order to make the code validate, you must add a <div> tag around the non-single elemnets, as shown below.

    <div>
    <script>...</script>
    <script>...</script>
    </div>
  2. With the newer XHTML standards, you cannot just include JavaScript between the script tags without potentially breaking validation. To fix this problem, use the tag <![CDATA[ ...]]> around the JavaScript code, as shown below.

    <script>
    <![CDATA[
    ...
    ]]>
    </script>
