我正在尝试使用 xsl 样式表显示 xml 文件。我似乎无法让它工作。
我正在使用的提要是这样的：http ://screamingdeals.tdn.travelscream.com/atom.xml
这是它的 xml 的缩写副本：
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:ts="http://www.travelscream.com">

加载样式表并告诉它转换 xml 的 php 页面是这样编码的：
$xp = new XsltProcessor();
// create a DOM document and load the XSL stylesheet
$xsl = new DomDocument;
$xsl->load('deals_stylesheet.xsl');
// import the XSL styelsheet into the XSLT process
$xp->importStylesheet($xsl);
// create a DOM document and load the XML datat
$xml_doc = new DomDocument;
$xml_doc->load('http://screamingdeals.tdn.travelscream.com/atom.xml');
// transform the XML into HTML using the XSL file
if ($html = $xp->transformToXML($xml_doc)) {
echo $html;
} else {
trigger_error('XSL transformation failed.', E_USER_ERROR);
} // if
到目前为止，一切都很好。我没有收到错误。这是 xsl 文件的内容：
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>Facebook Deals Page</title>
<style type="text/css">
<![CDATA[
<!--
-->
]]>
</style>
</head>
<body>
<table border="1">
<tr>
<td><b>Title</b></td>
<td><b>ID</b></td>
</tr>
<xsl:for-each select="feed/entry">
<tr>
<td><xsl:value-of select="title"/></td>
<td><xsl:value-of select="id"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
这是它不起作用的显示：http: //www.margaretpickarddesign.com/clients/travelscream/facebook_deals/facebook_rss.php
查看 xml 结构，节点“feed”之后是节点“entry”，该节点具有子节点“title”和“id”。那么为什么它不起作用呢？我错过了什么？
