phpXMLWriter类的简单示例

代码很简单,如下所示:

query("SELECT * FROM post");
$xml = new XMLWriter();
$xml->openUri(&＃39;hello.xml&＃39;); //  or &＃39;php://output&＃39;
$xml->setIndentString(&＃39;   &＃39;);
$xml->setIndent(true);
// start
$xml->startDocument(&＃39;1.0&＃39;, &＃39;UTF-8&＃39;);
// 
$xml->startElement(&＃39;rss&＃39;);
$xml->writeAttribute(&＃39;version&＃39;, &＃39;2.0&＃39;);
// 
$xml->startElement(&＃39;channel&＃39;);
// title
$xml->startElement(&＃39;title&＃39;);
$xml->text(&＃39;title&＃39;);
$xml->endElement();
// link
$xml->startElement(&＃39;link&＃39;);
$xml->text(&＃39;http://foodstory.me/post/&＃39;);
$xml->endElement();
// description
$xml->startElement(&＃39;description&＃39;);
$xml->text(&＃39;&＃39;);
$xml->endElement();
// language
$xml->startElement(&＃39;language&＃39;);
$xml->text(&＃39;zh-cn&＃39;);
$xml->endElement();
// category
$xml->startElement(&＃39;category&＃39;);
$xml->text(&＃39;IT&＃39;);
$xml->endElement();
// copyright
$xml->startElement(&＃39;copyright&＃39;);
$xml->text(&＃39;copyright 2011 foodstory.me&＃39;);
$xml->endElement();
// for item
while ($row = $mysql->fetch()) {
    $xml->startElement(&＃39;item&＃39;);
    // title
    $xml->startElement(&＃39;title&＃39;);
    $xml->text($row[&＃39;title&＃39;]);
    $xml->endElement();
    // link
    $xml->startElement(&＃39;link&＃39;);
    $xml->text(&＃39;http://foodstory.me/post/&＃39; . $row[&＃39;id&＃39;] . &＃39;.html&＃39;);
    $xml->endElement();
    // description
    $xml->startElement(&＃39;description&＃39;);
    $xml->text($row[&＃39;text&＃39;]);
    $xml->endElement();
    // pubDate
    $xml->startElement(&＃39;pubDate&＃39;);
    $xml->text(date(&＃39;D, d M Y H:i:s T&＃39;, $row[&＃39;time&＃39;]));
    $xml->endElement();
    // category tag author need to write .over
    $xml->endElement(); // item
    
}
$xml->endElement(); // channel
$xml->endElement(); // rss
$xml->endDocument();
// $xml->flush();
?>

openUri(&＃39;&＃39;) 方法的参数可以是一个文件,那么xml数据就写入到这个文件或者 php://output 输出到缓冲区,然后 flush方法输出到页面.
