Question

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Feed是：http://screamingdeals.tdn.travelscream.com/atom.xml

以下是xml的缩写副本：

<feed xmlns="http://www.w3.org/2005/Atom" xmlns:ts="http://www.travelscream.com">
    <title type="text">Travelscream Deal Alerts</title>

加载样式表并告诉它转换xml的php页面如此编码：

$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......太好了。我没有收到错误。这是xsl文件内容：

<?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>

这是显示它不起作用：http://www.margaretpickarddesign.com/clients/travelscream/facebook_deals/facebook_rss.php

查看xml结构，节点“feed”后跟节点“entry”，其中包含子节点“title”和“id”。那为什么不工作呢？我错过了什么？

添加评论作为实际答案......

ts前缀命名空间不是问题，因为您没有访问该命名空间中的任何元素。问题是默认命名空间（没有前缀的xmlns）。

您需要做的是将xmlns:a="http://www.w3.org/2005/Atom"添加到xsl:stylesheet并在您的选择中使用该前缀。（select="a:feed/a:entry"，select="a:title"和select="a:id"）

另请注意，您可以使用任何前缀，而不仅仅是“a”。唯一必须相同的是命名空间本身（http://www.w3.org/2005/Atom）。

为什么xsl：for-each select =“”不能使用这个xml文件？
