XSLT：

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:template match="feed"> 
<html> 
<body> 
    <h2>My Videos</h2> 
    <table border="1"> 
    <tr bgcolor="#9acd32"> 
     <th style="text-align:left">Title</th> 
     <th style="text-align:left">Image URL</th> 
    </tr> 
    <xsl:for-each select="entry"> 
    <tr> 
     <td><xsl:value-of select="title"/></td> 
     <td><xsl:value-of select="media:thumbnail/@url"/></td> 
    </tr> 
    </xsl:for-each> 
    </table> 
</body> 
</html> 
</xsl:template> 
</xsl:stylesheet>

想通了。您需要重命名XSLT文件中源XML文件的名称空间（默认或其他名称空间）。

所以在源文件中，你的命名空间：xmlns:yt="http://www.youtube.com/xml/schemas/2015" xmlns:media="http://search.yahoo.com/mrss/" xmlns="http://www.w3.org/2005/Atom"

所以这些添加到您的XSLT文件，以及...但是....你必须给默认xmlns明确的前缀。所以我给它一个d，如默认。所以在XSLT，该命名空间，你必须xmlns:d="http://www.w3.org/2005/Atom"

最终XSLT：

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:media="http://search.yahoo.com/mrss/" xmlns:d="http://www.w3.org/2005/Atom" > 
<xsl:template match="d:feed"> 
<html> 
<body> 
    <h2>My Videos</h2> 
    <table border="1"> 
    <tr bgcolor="#9acd32"> 
     <th style="text-align:left">Title<xsl:value-of select="d:id"/></th> 
     <th style="text-align:left">Image URL</th> 
    </tr> 
    <xsl:for-each select="d:entry"> 
    <tr> 
     <td><xsl:value-of select="d:title"/></td> 
     <td><img> 
      <xsl:attribute name="src"> 
       <xsl:value-of select='media:group/media:thumbnail/@url'/> 
      </xsl:attribute> 
      </img> 
     </td> 
    </tr> 
    </xsl:for-each> 
    </table> 
</body> 
</html> 
</xsl:template> 
</xsl:stylesheet>
