使用PHP的DOMDocument时，避免使用百分比编码的href属性 [英] Avoid percent-encoding href attributes when using PHP's DOMDocument
问题描述
我能找到的关于此问题的最佳答案是使用XSLT，但我不确定如何将这些答案应用于我的问题.
The best answers I was able to find for this issue are using XSLT, but I'm just not sure how to apply those answers to my problem.
基本上，DOMDocument在转义传入的URL(在 href 属性中)方面做得很好，但实际上我正在使用它来构建Twig/Django样式模板，d宁愿让他们一个人呆着.这是一个具体的示例，说明了问题":
Basically, DOMDocument is doing a fine job of escaping URLs (in href attributes) that are passed in, but I'm actually using it to build a Twig/Django style template, and I'd rather it leave them alone. Here's a specific example, illustrating the "problem":
<?php
$doc = new DOMDocument();
$doc->loadHTML('<html><body>Test<br><a href="{{variable}}"></a></body></html>');
echo $doc->saveHTML();
输出以下内容:
<html><body>Test<br><a href="%7B%7Bvariable%7D%7D"></a></body></html>
是否可以不对 href 属性进行百分比编码?
Is it possible to NOT percent-encode the href attribute?
如果不可能直接 ，您能提出一种简洁可靠的解决方法吗?我正在做其他处理，因此必须保留DOMDocument的用法.那么也许是前/后处理的把戏?
If it's not possible directly, can you suggest a concise and reliable workaround? I'm doing other processing, and the DOMDocument usage will have to stay. So perhaps a pre/post processing trick?
推荐答案
我对'hack'/duct-tape解决方案不满意，但这是我目前正在解决的问题:
I'm not happy with the 'hack'/duct-tape solution, but this is how I'm currently solving the problem:
function fix_template_variable_tokens($template_string)
{
$pattern = "/%7B%7B(\w+)%7D%7D/";
$replacement = '{{$1}}';
return preg_replace($pattern, $replacement, $template_string);
}
$html = $doc->saveHTML();
$html = fix_template_variable_tokens($html);
