description:dom处理标签script闭合时会将script标签里的数据丢失一部分

Description:
------------
使用DOMDocument对一段字符串进行标签闭合处理时，如果字符串包含有script标签，在<script></script>标签里的其他的标签会在进行标签闭合处理时，会出现丢失。如字符串：<b>aaaaa<div
         
ID="te<te"st>st">&nbsp;startstartstartenhao好开始测<b>试编辑器\n提交的数据<br>呵\n呵<br>哈哈<br>嗯endendendend\n\n<br></div><script><span>111</span>alert("<span>你好！</span>")</script>。
其中<script><span>111</span>alert("<span>你好！</span>")</script>这段字符串会在经过：
$dom = new DOMDocument();

$dom->loadHTML('<html><head><meta http-equiv="Content-Type"
content="text/html; charset=utf-8"></head><body>' . $html .
'</body></html>');

$html = $dom->saveHTML();
这些函数处理后，变成：
<script><span>111alert("<span>你好！")</script>
不知为什么会是这样的结果


Test script:
---------------
完整的测试代码段为：

$html = '<b>aaaaa<div          
ID="te<te"st>st">&nbsp;startstartstartenhao好开始测<b>试编辑器\n提交的数据<br>呵\n呵<br>哈哈<br>嗯endendendend\n\n<br></div><script><span>111</span>alert("<span>你好！</span>")</script>';


libxml_clear_errors();

$libxml_use_errors = libxml_use_internal_errors(true);

$dom = new DOMDocument();

$dom->loadHTML('<html><head><meta http-equiv="Content-Type"
content="text/html; charset=utf-8"></head><body>' . $html .
'</body></html>');

$html = $dom->saveHTML();

$body_start = strpos($html, '<body>');
$body_end = strrpos($html, '</body>');
$new_string = str_replace("\n", '', substr($html, $body_start + 6,
$body_end - $body_start - 6));

libxml_use_internal_errors($libxml_use_errors);

echo $html . "\n" . $new_string . "\n";


Expected result:
----------------
测试字符串：
<script><span>111</span>alert("<span>你好！</span>")</script>

经过:$dom = new DOMDocument();

$dom->loadHTML('<html><head><meta http-equiv="Content-Type"
content="text/html; charset=utf-8"></head><body>' . $html .
'</body></html>');

$html = $dom->saveHTML();处理后，

希望还应该是：
<script><span>111</span>alert("<span>你好！</span>")</script>


Actual result:
--------------
如字符串：
<script><span>111</span>alert("<span>你好！</span>")</script>

现在的返回结果是：
<script><span>111alert("<span>你好！")</script>
