在 SimpleXML for PHP 中关闭自闭合标签? [英] Turn OFF self-closing tags in SimpleXML for PHP?

问题描述

我正在构建一个带有 PHP 的 SimpleXML 扩展的 XML 文档，我正在向文件中添加一个标记:

I'm building an XML document with PHP's SimpleXML extension, and I'm adding a token to the file:

$doc->addChild('myToken');

这会生成(我所知道的)一个自闭合标签或单个标签:

This generates (what I know as) a self-closing or single tag:

<myToken/>

但是，我正在与之通信的老化网络服务正在被自闭标签绊倒，所以我需要有一个单独的开始和结束标签:

However, the aging web-service I'm communicating with is tripping all over self-closing tags, so I need to have a separate opening and closing tag:

<myToken></myToken>

问题是，除了通过 preg_replace 运行生成的 XML 之外，我该怎么做?

The question is, how do I do this, outside of running the generated XML through a preg_replace?

推荐答案

来自 SimpleXMLElement->__construct 和 LibXML 预定义常量，我认为这应该有效:

From the documentation at SimpleXMLElement->__construct and LibXML Predefined Constants, I think this should work:

<?php
$sxe = new SimpleXMLElement($someData, LIBXML_NOEMPTYTAG);

// some processing here

$out = $sxe->asXML();
?>

试试看是否有效.否则，恐怕就是 preg_replace-land.

Try that and see if it works. Otherwise, I'm afraid, it's preg_replace-land.
