parsing of an unknown XML, getting node names without XPATH

本文关键字：XPATH 节点获取未知 XML | 更新日期: 2024-05-01

我使用简化的SQL编写简单的XML解析器。我有一个类似的东西

`<catalog>
    <library><room id="1">
    <book id="bk101">
      <author>Gambardella, Matthew</author>
      <title>XML Developer's Guide</title>
      <genre>Computer</genre>
      <price>44.95</price>
      <publish_date>2000-10-01</publish_date>
      <description>An in-depth look at creating applications 
      with XML.</description>
   </book></room>
   <room id="2">
   <book id="bk102">
      <author>Ralls, Kim</author>
      <title>Midnight Rain</title>
      <genre>Fantasy</genre>
      <price>5.95</price>
      <publish_date>2000-12-16</publish_date>
      <description>A former architect battles corporate zombies, 
      an evil sorceress, and her own childhood to become queen 
      of the world.</description>
   </book></room>
   </library>`

我需要得到这个：

`<Books><book id="bk101">
  <author>Gambardella, Matthew</author>
  <title>XML Developer's Guide</title>
  <genre>Computer</genre>
  <price>44.95</price>
  <publish_date>2000-10-01</publish_date>
  <description>An in-depth look at creating applications 
  with XML.</description>
  </book><book id="bk102">
  <author>Ralls, Kim</author>
  <title>Midnight Rain</title>
  <genre>Fantasy</genre>
  <price>5.95</price>
  <publish_date>2000-12-16</publish_date>
  <description>A former architect battles corporate zombies, 
  an evil sorceress, and her own childhood to become queen 
  of the world.</description>

我真的不知道该怎么办…你能给我建议吗我不能使用xpath。

首先打开要处理元素的文档：

$doc = new DOMDocument();
$doc->recover = true;
$doc->loadXML($buffer);

然后创建一个新文档，将元素添加到其中：

$books = new DOMDocument();
$books->preserveWhiteSpace = false;
$books->formatOutput = true;
$books->loadXML('<Books/>');

然后将<book>元素节点从第一个文档导入第二个文档，然后将它们附加到文档元素：

foreach ($doc->getElementsByTagName('book') as $book) {
    $book = $books->importNode($book, true);
    $books->documentElement->appendChild($book);
}

然后，您可以重新加载文档以进行格式化并输出它：

$books->loadXML($books->saveXML());
$books->save('php://output');

输出：

<?xml version="1.0"?>
