任何人都可以提供任何帮助/建议解析HTML标记出现在<body>...</body>标记旁边

Answer 1

我想你想用PHP解析HTML文档。我建议你阅读 http://www.php.net/manual/en/book.dom.php

提供的示例

<?php

$html = '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" dir="ltr">
<head>
<title>PHPRO.ORG</title>
</head>
<body>
