Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php 你使用了libxml_use_internal_errors静默了错误提示. 实际上PHP已经告诉了你: PHP Warning: DOMDocument::loadHTML(): Unexpected end tag : span in Entity // I'd like to mark this as a Nab, since PHP will warning you about the abnormal html like: PHP Warning: DOMDocument::loadHTML(): Unexpected end tag : span in Entity but you used libxml_use_internal_errors to suppress it. thanks ------------------------------------------------------------------------ [2012-11-02 07:27:44] icewavestone at gmail dot com 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> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63417&edit=1
