如何在RSS中显示图像? [英] How to display image in RSS?

问题描述

我正在尝试编写一个非常简单的RSS频道，该频道将显示sinfest.net上当日的漫画，但是我不能强迫它显示除链接标题以外的任何内容. 链接到其中一个代码版本:

I am trying to write a very simple RSS channel which would display the current day's comic strip from sinfest.net, but I cannot force it to display anything but the linked title. Link to one of the code versions:

<?php
$page = file_get_contents('http://www.sinfest.net/index.php');
$title = '';
$description = '';
$link = '';
$date = date("Y-m-d");
if (preg_match('~<img src="(http://sinfest\\.net/comikaze/comics/.*\\.gif)" alt="(.*)" border="0" />~isU', $page, $match)) {
        $title = $match[2];
        $description = "<img src='{$match[1]}'/>";
}
if (preg_match('~<a href="http://sinfest\\.net/archive_page\\.php\\?comicID=([0-9]*)"><img src="images/prev_a.gif"~isU', $page, $match)) {
        $link = 'http://sinfest.net/archive_page.php?comicID=' . ($match[1]+1);
}
$ok = $title && $description && $link;
$image = "http://www.sinfest.net/comikaze/comics/" . $date . ".gif";
echo '<?xml version="1.0" encoding="ISO-8859-1" ?>';
echo '<rss version="2.0">
        <channel>
                <title>Latest Sinfest</title>
                <link>http://www.sinfest.net/</link>
                <description>Latest Sinfest</description>
                <image>
                      <url>' . $image . '</url>
                      <title>' . htmlspecialchars($title) . '</title>
                      <link>' . htmlspecialchars($link) . '</link>
                </image>';
if ($ok):
echo '               <item>
                        <title>' . htmlspecialchars($title) . '</title>
                        <link>' . htmlspecialchars($link) . '</link>
                        <description><img src="' . $image . '" /></description>
                        <enclosure url="' . $image . '" type="image/jpeg" />
                </item>';
elseif (!isset($_GET['noerror'])): 
echo '                <item>
                        <title>Error parsing news.' . date('Y-m-d H:i:s') . '</title>
                        <link>about:blank</link>
                        <description>Error parsing news.</description>
                </item>';
endif;
echo '        </channel>
</rss>';
?>

仅RSS的代码(我没有删除PHP变量):

The RSS-only code (I didn't remove the PHP variables):

<?xml version="1.0" encoding="ISO-8859-1" ?>
<rss version="2.0">
    <channel>
        <title>Latest Sinfest</title>
        <link>http://www.sinfest.net/</link>
        <description>Latest Sinfest</description>
        <image>
            <url>' . $image . '</url>
            <title>' . htmlspecialchars($title) . '</title>
            <link>' . htmlspecialchars($link) . '</link>
        </image>
        <item>
            <title>' . htmlspecialchars($title) . '</title>
            <link>' . htmlspecialchars($link) . '</link>
            <description><img src="' . $image . '" /></description>
            <enclosure url="' . $image . '" type="image/jpeg" />
        </item>
    </channel>
</rss>

有什么主意我在做错什么，也许有一些建议吗?谢谢，谢谢.

Any idea what am I doing wrong and some piece of advice maybe? Thank is advance.

推荐答案

您最好的选择是CDATA该图像部分(或者，您也可以"htmlentities()"它，但这更好！)

Your best bet is to CDATA that image section (alternatively you can "htmlentities()" it, but this is better!)

<description><![CDATA[<img src="' . $image . '" />]]></description>
