Question

我有两个php变量： 1）$item1 = "baking"; 2）$item2 = "fun";

这些变量需要插入到下面的DOM结构中。

<random>
      <li>
          I also think <star item="1"/> can be <star item="2"/> sometimes.
      </li>
  </random>

我使用以下代码获取“li”元素。

$elements = $dom->getElementsByTagName('li');

foreach ($elements as $node) {

  $sentence = $node->nodeValue;
// This will currently print "I also think can be sometimes."
}

如何将baking插入<star item="1"/>所在位置fun插入<star item="2"/>所在位置，以便最终结果为： < / p>

I also think baking can be fun sometimes.

这是一个快速实施配合，根据您的需要进行调整：

<?php
$xml = <<< XML
<?xml version="1.0" encoding="utf-8"?>
<random>
      <li>
          I also think <star item="1"/> can be <star item="2"/> sometimes.
      </li>
  </random>
XML;

$dom = new DOMDocument;
$dom->loadXML($xml);
$liElements = $dom->getElementsByTagName('li');

$starElements = $dom->getElementsByTagName('star');
$i = $starElements->length - 1; 
while ($i > -1) { 
$starElement = $starElements->item($i);
            if ( $starElement->nodeName == 'star' ) {
                if ($starElement->getAttribute('item') == 1) {
                 $newelement = $dom->createTextNode('baking'); 
                 $starElement->parentNode->replaceChild($newelement, $starElement);
                } else if ($starElement->getAttribute('item') == 2) {
                 $newelement = $dom->createTextNode('fun'); 
                 $starElement->parentNode->replaceChild($newelement, $starElement);
                }
            }
        $i--;
    }

foreach ($liElements as $node) {
  echo $node->nodeValue;
}
?>

PHP：将变量插入到DOM结构中＆lt; tag item =“＃”/＆gt;找到了
