我在DotNetNuke中安装了一个RSS阅读器模块。我必须配置XSL以便以可读格式获取输出。 RSS如下：

我使用的XSL文件如下：
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<table border="1">

<th>Title</th>
<th>Author</th>
<th>Updated</th>

<xsl:for-each select="feed/entry">

</xsl:for-each>

我收到以下错误。
System.Xml.Xsl.XslLoadException XSLT编译错误。有什么帮助吗？
答案 0 :(得分：0)
这是因为您尚未定义xsl名称空间。变化
<xsl:stylesheet version="1.0" xmlns="http://www.w3.org/1999/XSL/Transform">
到
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
您还需要添加一个'atom'命名空间，以使'for-each'和'value-of'指令有效，并且您可能希望禁用标题字段上的输出转义以在其中生成标记显示为标记。我建议这个：
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
