XSL - неизвестная ошибка на носителе FF: content / @ url

Question

Я продолжаю получать сообщение «Произошла неизвестная ошибка», когда я пытаюсь сделать это в своем XSLT:

<table class="TEDtalks">

    <xsl:for-each select="/rss/channel/item">
    <tr>

    <td><xsl:value-of select="title"/></td>

    <td>

    <xsl:value-of select="media:content/@url" />
    </td>

    </tr>
    </xsl:for-each>
</table>

XML

<rss>
<channel>
<item>

Определили ли вы префикс media: xml namespace? E.g.:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:media="http://search.yahoo.com/mrss/"
                ...
