标题几乎说明了一切。
如果我有类似的东西(来自 PHP 站点示例):
$xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<movies></movies>
XML;
$sxe = new SimpleXMLElement($xmlstr);
$sxe->addAttribute('type', 'documentary');
$movie = $sxe->addChild('movie');
$movie->addChild('title', 'PHP2: More Parser Stories');
$movie->addChild('plot', 'This is all about the people who make it work.');
$characters = $movie->addChild('characters');
$character = $characters->addChild('character');
$character->addChild('name', 'Mr. Parser');
$character->addChild('actor', 'John Doe');
$rating = $movie->addChild('rating', '5');
$rating->addAttribute('type', 'stars');
echo("<pre>".htmlspecialchars($sxe->asXML())."</pre>");
die();
我最终会像这样输出一个长字符串:
<?xml version="1.0" standalone="yes"?>
<movies type="documentary"><movie><title>PHP2: More Parser Stories</title><plot>This is all about the people who make it work.</plot><characters><character><name>Mr. Parser</name><actor>John Doe</actor></character></characters><rating type="stars">5</rating></movie></movies>
这对于程序使用者来说很好,但对于调试/人工任务,有谁知道如何将其转换为良好的缩进格式?
PHP manual page for SimpleXMLElement 的评论中有多种解决方案.不是很有效,但肯定很简洁,是 Anonymous 的解决方案
$dom = dom_import_simplexml($simpleXml)->ownerDocument;
$dom->formatOutput = true;
echo $dom->saveXML();
PHP 手册页注释通常是满足常见需求的好来源,只要您先过滤掉明显错误的内容。
我是一名优秀的程序员,十分优秀!
