Question

我为我写了这个RSS阅读器，它实际上工作得非常好，但遗憾的是我不了解PHP如何输出。有人可以帮我吗？

我的PHP代码：

$reader = new XMLReader();

$reader->open("articles.xml");

while ($reader->read())
{
  if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "title")
    echo "<h1>Pøehled aktuálních zpráv ze serveru
      <a href='" . htmlspecialchars($reader->readString(), ENT_QUOTES) . "'>" .
      $title . "</a></h1>";

  // obsluha názvu kanálu
  if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "link")
    $title = htmlspecialchars($reader->readString());

  if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "article")
  {
    echo "<dl>";
    while ($reader->read())
    {

      if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "link")
                echo "<dt><a href='" . htmlspecialchars($reader->readString(), ENT_QUOTES) . "'>" .
                    $title . "</a></dt>";

      if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "title")
                $title = htmlspecialchars($reader->readString());

      if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "description")
                echo "<dd>" .  htmlspecialchars($reader->readString()) . "</dd>";

    }

    echo "</dl>";
  }
}

这是输出 1.它使用desc显示该部分，然后显示作为链接的标题。但它应该是相反的顺序。

这可能是非常愚蠢的事情，但我对这段代码的关注时间太长而无法找到问题。

如果有人可以帮助我，我会很高兴。感谢

锚标记<a>的echo语句错误。我将$title与htmlspecialchars($reader->readString(), ENT_QUOTES)交换。

这应该是你想要的：

$reader = new XMLReader();
$reader->open("http://blog.omer.london/feed/");

$title = '';
while ($reader->read()) {
    if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "title") {
        echo "<h1>Pøehled aktuálních zpráv ze serveru
      <a href='" . $title . "'>" . htmlspecialchars($reader->readString(), ENT_QUOTES) . "</a></h1>";
    }

    // obsluha názvu kanálu
    if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "link") {
        $title = htmlspecialchars($reader->readString());
    } elseif ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "article") {
        echo "<dl>";
        while ($reader->read()) {
            if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "link") {
                echo "<dt><a href='" . $title . "'>" . htmlspecialchars($reader->readString(), ENT_QUOTES) . "</a></dt>";
            } elseif ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "title") {
                $title = htmlspecialchars($reader->readString());
            } elseif ($reader->nodeType == XMLReader::ELEMENT && $reader->name == "description") {
                echo "<dd>" . htmlspecialchars($reader->readString()) . "</dd>";
            }
        }
        echo "</dl>";
    }
}
