From: icewavestone at gmail dot com Operating system: all PHP version: 5.3.18 Package: DOM XML related Bug Type: Bug Bug 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> -- Edit bug report at https://bugs.php.net/bug.php?id=63417&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63417&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63417&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63417&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63417&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63417&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63417&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63417&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63417&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63417&r=support Expected behavior: https://bugs.php.net/fix.php?id=63417&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63417&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63417&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63417&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63417&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63417&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63417&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63417&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63417&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63417&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63417&r=mysqlcfg
