Question

请帮我处理以下XSL模板。我正在使用iframe来显示视频，但我不断收到错误。

<xsl:template match="Row">
    <div id="listitem-{@ID}">
            <div class="row">
            <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
            <div class="catalog-item">                  
               <img height="70" width="70" class="catalog-icon pull-left"><xsl:attribute name="src"><xsl:value-of select="@Picture" /></xsl:attribute></img>                  
               <span class="catalog-item-title"><xsl:value-of select="@Title" disable-output-escaping="yes"/></span>
               <div class="aliases">Aliases: <xsl:value-of select="@Aliases" disable-output-escaping="yes"/> </div>
            </div> 
            </div>
            </div>
            <div class="row">
            <div class="col-lg-8 col-md-8 col-sm-12 col-xs-12">    
               <div class="catalog-descr"><xsl:value-of select="@Description" disable-output-escaping="yes"/></div> 
            </div>
             <div class="col-lg-4 col-md-4 col-sm-12 col-xs-12">
                <div class="video-responsive">
                <iframe width="420" height="315" src="{@Youtube}"></iframe>
                </div>                   
            </div>
            </div>
