            View and edit the office docs on your phone. Quickly and easily cut through
            the clutter to see only the unread, urgent, or flagged messages in your
            Outlook inbox. And use SharePoint, when you need a little bit of help from
            your team to crack the project.The slide and tilt screen on the HTC 7 Pro
            angles perfectly to reveal a dedicated QWERTY keyboard. The keys are raised
            and nicely spaced for fast and comfortable typing. And because the screen
            tilts, the HTC 7 Pro is perfect for watching videos - hands free - when you
            have a brief moment to kick back and relax.

Answer 1

Ну, у вас есть несколько ошибок.

• Вы неправильно закрыли свои метки доставки. Они должны быть:

<shipping>
    <cost>$0.00</cost>
    <speed>Expedited Shipping</speed> 
</shipping>

• Вы пропустили последний закрывающий тег:

</phones>

• Я считаю, что Chrome дает очень полезные сообщения об ошибках, чтобы помочь исправить ошибки XML. Например, прежде чем я исправил закрывающий тег </phones>, сообщение об ошибке в Chrome показало:

This page contains the following errors:

error on line 129 at column 10: Extra content at the end of the document
Below is a rendering of the page up to the first error.

Answer 2

В дополнение к ошибкам корректности, уже упомянутым manishie, необходимо исправить некорректное объявление типа документа:

<?DOCTYPE ... >

читать

<!DOCTYPE ... >

Когда я исправляю это, а также ошибки WF, страница отображается нормально, и стиль CSS, кажется, используется, как и следовало ожидать.

При плохом объявлении DOCTYPE анализатор идентифицирует - таким образом проглатывая вашу инструкцию xml-stylesheet. Я понятия не имею, почему вы видели первую часть документа, а не весь документ.
