Recent manually built Extended CHM has a corrupt index page.

Hi, phpdoc/htmlhelp/filter_files.php has a problem creating the new _index.html file. The output currently is ... <a id="user_notes"></a><div id="pageNotes"></div><script type="text/javascript" language="JavaScript1.2"> function displayNotes() { _displayNotes(); } if (typeof loadNotes == "function") { loadNotes(); } </script><div id="pageNav"><table width="100%" border="0" cellspacing="10" cellpadding="0" class="navigation"><tr align="left" valign="middle"><td width="30%"></td><td align="center" width="40%"><span id="navPath">Main</span></td><td align="right" width="30%"><span id="navNext"><a accesskey="n" href="preface.html">Preface &gt;&gt;</a></span></td></tr><tr align="center" valign="middle"><td colspan="3"><span id="navOnline"><span id="navThisOnline"><a href="javascript:thisPageOnline();">This page online</a></span> &nbsp; <span id="navReportBug"><a href="javascript:bugOnPage();">Report a bug</a></span></span></td></tr></table></div></div></body></html> The code causing the problem is bizarre. filter_files.php // $Id: filter_files.php,v 1.17 2005/07/01 22:27:04 techtonik Exp $ Lines 240-247 (Part of function newIndex ($content)) // Get contents we need to build the _index.html file preg_match("!^(.+)<hr>!s", $content, $_index1); preg_match("!</div></div>(<a id=\"user_notes\">.+</html>)!s", $content, $_index2); // Write out the two components to form a complete file $fp = fopen("$HTML_TARGET/_index.html", "w"); fwrite($fp, $_index1[1] . $_index2[1]); fclose($fp); Even though the $content DOES containt <hr>, then value in $_index1[1] is blank. This is going to be one of those REALLY obvious problems which has stumped me for ages. I can redo the code using string manipulation, but why the regex doesn't work,I don't know. I'm using PHPV5.2.0-dev and am just downloading the latest snapshot. I can confirm that the expression works in my editor (I added a file_put_contents('test.html', $content); and used that with the expression - worked fine!). Regards, Richard Quadling.
