是的，这是重复的。投票结束。 - Eli

大家好，

标题几乎全都说。 b

如果我有类似的东西（从php站点的例子）：

  $ xmlstr =< << XML 
<？xml version ='1.0'standalone ='yes'？> 
<电影>< /电影> 
 XML; 
 
 $ sxe = new SimpleXMLElement（$ xmlstr）; 
 
 $ sxe-> addAttribute（'type'，'documentary'）; 
 
 $ movie = $ sxe-> addChild（'movie'）; 
 $ movie-> addChild（'title'，'PHP2：More Parser Stories'）; 
 $ movie-> addChild（'plot'，'这是所有关于使它工作的人。'）; 
 
 $ 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'）; 
 
 $ b echo（< pre>。htmlspecialchars（$ sxe-> asXML（））。< / pre>）; 
 
 die（）; 
  

最后输出一个长字符串如下：

 <？xml version =1.0standalone =yes？> 
< movie type =documentary>< movie>< title> PHP2：更多解析器故事< / title>< plot>< / plot> ;<字符><字符><名称>先生。 < / movies>< / rating>< / actor> John Doe< / actor>< / character>< / characters>< rating type =stars> 5< / rating>< / movie>< / movies> 
  

这对程序使用者来说是好的，但是对于调试/人工任务，没有人知道如何获得这到一个很好的缩进格式？

解决方案

在 SimpleXMLElement的PHP手册页面。不是非常有效率，但肯定是简洁，是一个由匿名解决方案

  $ dom = dom_import_simplexml（$ simpleXml） - > ownerDocument; 
 $ dom-> formatOutput = true; 
 echo $ dom-> saveXML（）; 
  

PHP手册页面注释通常是常见需求的良好来源，只要您明确地过滤掉错误的东西先。

Hi All,

The title pretty much says it all.

If I have something like (from the php site examples):

 $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();

I end up outputing a long string like so:

<?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>

This is fine for a program consumer, but for debugging/human tasks, does anyone know how to get this into a nice indented format?

解决方案

There's a variety of solutions in the comments on the PHP manual page for SimpleXMLElement. Not very efficient, but certainly terse, is a solution by Anonymous

$dom = dom_import_simplexml($simpleXml)->ownerDocument;
$dom->formatOutput = true;
echo $dom->saveXML();

The PHP manual page comments are often good sources for common needs, as long as you filter out the patently wrong stuff first.
