formasfunction Posted May 18, 2007 Share Posted May 18, 2007 I'm trying to write a regular expression that will take a chunk of html and modify the body tag but I'm having trouble as this is my first regex attempt. Here's what I have: $_response_body = whatever html I'm feeding in $pattern = '<body \b[^>]*>'; $replacement = '\\1 <div id="top_frame"><div id="nav_bar">text</div><div id="sub_bar">text</div></div>'; echo $_response_body = preg_replace($pattern, $replacement, $_response_body); So I'm hoping that this would take something like <body class="home"> or <body class="main"> and turn them into: <body class="home"><div id="top_frame"><div id="nav_bar">text</div><div id="sub_bar">text</div></div> or <body class="main"><div id="top_frame"><div id="nav_bar">text</div><div id="sub_bar">text</div></div> Thanks in advance.

taith Posted May 18, 2007 Share Posted May 18, 2007 wow... theres alot of confusion for such a simple switch! lol <?php if(empty($bodytag)) $bodytag='main'; ?> <body class="<?=$bodytag?>"> then on any page you want to change the class, just give $bodytag a value...

formasfunction Posted May 18, 2007 Author Share Posted May 18, 2007 Sorry, I don't think I was clear enough. I don't want to change the class of the body, I want to find the opening body tag regardless of whether or not it has a class attached to it and add a chunk of code after it. If it was always a predictable tag (like always just <body> with no class) then I'd use a str_replace and append my new code at the end.

effigy Posted May 18, 2007 Share Posted May 18, 2007 /<body[^>]*>/ Quote Link to comment Share on other sites More sharing options...
formasfunction Posted May 18, 2007 Author Share Posted May 18, 2007 Thanks effigy, that works great. Am I doing my backreference correctly in $replacement? Quote Link to comment Share on other sites More sharing options...
effigy Posted May 18, 2007 Share Posted May 18, 2007 Ah, I didn't catch that; you'll need /(<body[^>]*>)/. You don't need both backslashes in the replace, but it'll work. Quote Link to comment Share on other sites More sharing options...
