Question

试图找出解析无效XML的最有效方法（在php中）。

我尝试解析的元素包含嵌套的，我希望输出到自己的xml文档。

我尝试过简单的XML，但我一直遇到错误。尝试使用DOM，它似乎运作良好，但只能导致能够输出文本。非常感谢您的帮助。

示例XML：

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

简单，只需将元素节点附加到新文档即可。

$source = new DOMDocument();
$source->loadXml($sampleXml);
$xpath = new DOMXpath($dom);

$target = new DOMDocument();
$target->appendChild(
  $target->importNode($xpath->evaluate('//VAST')->item(0), TRUE)
);

echo $target->saveXml();

PHP - 解析无效的XML并输出到自己的xml文档
