xml - PHPUnit 中的测试结构 XML

Question

我看到 assertEqualXMLStructure 能够在 PHPUnit 中使用测试结构 XML。但是我遇到了案例问题：当 2 个结构 XML 具有不同的子标签数量时，尽管结构相同，但它失败了。有没有办法通过 PHPUnit 的支持来做到这一点？谢谢

通过编辑 assertEqualXMLStructure 以忽略检查标签子项的数量，我解决了我的问题：

public static function assertEqualXMLStructure(DOMElement $expectedElement, DOMElement $actualElement, $checkAttributes = FALSE, $message = '') {
  self::assertEquals($expectedElement->tagName, $actualElement->tagName, $message);

  if ($checkAttributes) {
    self::assertEquals($expectedElement->attributes->length, $actualElement->attributes->length, sprintf('%s%sNumber of attributes on node "%s" does not match', $message, !empty($message) ? "\n" : '', $expectedElement->tagName));

    for ($i = 0; $i < $expectedElement->attributes->length; $i++) {
      $expectedAttribute = $expectedElement->attributes->item($i);
      $actualAttribute = $actualElement->attributes->getNamedItem($expectedAttribute->name);

      if (!$actualAttribute) {
        self::fail(sprintf('%s%sCould not find attribute "%s" on node "%s"', $message, !empty($message) ? "\n" : '', $expectedAttribute->name, $expectedElement->tagName));
      }
    }
  }

  PHPUnit_Util_XML::removeCharacterDataNodes($expectedElement);
  PHPUnit_Util_XML::removeCharacterDataNodes($actualElement);



  for ($i = 0; $i < $expectedElement->childNodes->length; $i++) {
    self::assertEqualXMLStructure($expectedElement->childNodes->item($i), $actualElement->childNodes->item($i), $checkAttributes, $message);
  }
}
