使用php的SimpleXMLItterator按顺序打印子元素

Question

我正在处理以下问题XML：

<Paragraph>This is a test. This is a test.
<Italic>This is an italicized test</Italic>
This is more tests
 </Paragraph>

我正在尝试拉入 XML，将其修改为文本字符串或 HTML 代码，然后将其吐出。我运行遇到了一个问题，我认为没有办法让所有这些文本保持正确的顺序。这是我的代码：

$xml = "<Paragraph>This is a test. This is a test.
<Italic>This is an italicized test</Italic>
This is more tests
 </Paragraph>";
$itterator = new SimpleXmlIterator($xml);
$non_italicized = $itterator->__toString();
for ($itterator->rewind(); $itterator->valid(); $itterator->next()) {
  $italicized = $itterator->current()->__toString();
}

$non_italicized的输出：

 This is a test. This is a test.
 This is more tests

$斜体的输出：

This is an italisized test

这让我无法将它们组合成一个常规段落，中间使用斜体文本。我怎样才能做到这一点？

Answer 1

您可以使用 DOM 执行此操作：

$doc = new DOMDocument();
$doc->loadXML($xml);

foreach ($doc->childNodes->item(0)->childNodes as $i) {
    echo "Element is: " . $i->nodeName . " Value is: " . trim($i->nodeValue) . "\n";
}

输出将是：

Element is: #text Value is: This is a test. This is a test.
Element is: Italic Value is: This is an italicized test
Element is: #text Value is: This is more tests

但是，如果将常规文本包含在某些标签中，会更容易。
