Bug #78129 [Com]: DOMDocument removes whitespace between nodes

Edit report at https://bugs.php.net/bug.php?id=78129&edit=1 ID: 78129 Comment by: nospam at unclassified dot de Reported by: nospam at unclassified dot de Summary: DOMDocument removes whitespace between nodes Status: Open Type: Bug Package: *General Issues Operating System: Linux PHP Version: 7.3.6 Block user comment: N Private report: N New Comment: Can somebody please have a quick look at this? To me this looks like a simple fix, just edit that one line that sets the option for the Linux build. Previous Comments: ------------------------------------------------------------------------ [2019-06-08 14:41:14] nospam at unclassified dot de It seems Linux always adds the LIBXML_NOBLANKS option whereas Windows does not. I can get the same result on Windows as on Linux when I use this code: $dom->loadHTML($html, LIBXML_NOBLANKS); But there is not option that inverts that option. To me it looks like the Linux build of PHP has the bug that the LIBXML_NOBLANKS option is always added while it should not. I couldn't find information about that option because the libxml documentation has no description of this option. It's just empty. ------------------------------------------------------------------------ [2019-06-08 14:31:05] nospam at unclassified dot de Description: ------------ The DOMDocument removes whitespace between HTML elements when loading and saving HTML content. This leads to wrong display of content. The bug only affects Linux, it works correctly in Windows (same version). Test script: --------------- <?php $html = '<html> <body> <p> Text </p> <lang>Logged in as</lang> <strong>user</strong> <script src="jquery-3.4.1.min.js"></script> <script src="site.js"></script> </body> </html>'; libxml_use_internal_errors(true); $dom = new DOMDocument(); $dom->loadHTML($html); header('Content-Type: text/plain'); echo $dom->saveHTML(); Expected result: ---------------- This is the output on Windows: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html> <body> <p> Text </p> <lang>Logged in as</lang> <strong>user</strong> <script src="jquery-3.4.1.min.js"></script> <script src="site.js"></script> </body> </html> Actual result: -------------- This is the output on Linux: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html><body> <p> Text </p> <lang>Logged in as</lang><strong>user</strong> <script src="jquery-3.4.1.min.js"></script><script src="site.js"></script></body></html> There is no space between "Logged in as" and "user". The <lang> element is a custom element that my PHP script will resolve into plain HTML. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78129&edit=1
