Need some Regular Expressions (PHP) to find and parse Script Codes on HTML website

Hello! Please find my detailed project description in the additional information area. Here is not enough space for it. Marc ## Deliverables What I need are regular expressions in PHP to find Google Adsense script codes on websites to parse them and to replace them. I build some regular expressions which work fine if the Adsense scripts are inserted regularly but - god knows why - a lot of users add some comments here, delete the new line commands or something else. So I need some more flexible regular expressions. Let me start with a typical standard adsense script: <script type="text/javascript"><!-- google_ad_client = "pub-7676581854075673"; /* 300x250, Erstellt 11.11.10 */ google_ad_slot = "7343419665"; google_ad_width = 300; google_ad_height = 250; //--> </script> <script type="text/javascript" src="<[login to view URL]>"> </script> The RegEx I already use to find this script and parse some values is this one: if( preg_match_all('|(<script type="text/javascript">[^>]*google_ad_client[^<]*</script>)|i', $content, $match) ){ foreach( $match[1] as $content){ if( preg_match('|google_ad_client\s*=\s*"[^"]*".*?google_ad_slot\s*=\s*"\d+"|i', $content, $temp) ){ $pub = get_hash($content, "google_ad_client"); $pub = str_replace("ca-","",$pub); $ads = get_hash($content, "google_ad_slot"); $wid = get_hash($content, "google_ad_width"); $hgt = get_hash($content, "google_ad_height"); [...] and the RegEx to find the Adsense script to replace/delete it completly I use is this one: $this->response_body = preg_replace('/<script type="text\/javascript"><\!\-\-[\r\n\t ]*google_ad_client = "'.$pub_id.'pub\-[^>]+>[\r\n\t ]*<\/script>[\r\n\t ]*<script[^>]+show_ads\.js">[\r\n\t ]*<\/script>/is', '', $this->response_body); ($pub_id is known here) Okay. That scripts work fine if the Adsense script is implemented reguarly. Now please find some irregular implementations I found and please build a RegEx as flexible as possible to find such irregular codes. With "flexible" I mean that your RegEx should not be able only to work together with the here listed individual examples. What I mean is: If for example in an example script a comment is placed like <script type="text/javascript"><!--// <![CDATA[ [...] your script should be flexible enough also to find <script type="text/javascript"><!--// <![CDATA2[ [...] Okay, but I this this point is clear anyway. ;-) And now please find here 8 irregular inplemented Adsense scripts: <div style="padding-bottom:14px;"><script type="text/javascript"><!-- google_ad_client = "pub-1126182868641892"; /* GifMixde_468x15-5:Start Haupt */ google_ad_slot = "2751397243"; google_ad_width = 560; google_ad_height = 15; //--> </script> <script type="text/javascript" src="<[login to view URL]>"> </script></div> <div style="padding-bottom:14px;"><script type="text/javascript"><!-- google_ad_client = "pub-1126182868641892"; /* GifMixde_468x15-5:Start Haupt */ google_ad_slot = "2751397243"; google_ad_width = 560; google_ad_height = 15; //--> </script> <script type="text/javascript" src="<[login to view URL]>"> </script></div> <script type="text/javascript"><!-- google_ad_client = "pub-9794464753711083"; /* 160x600, Erstellt 31.03.10 */ google_ad_slot = "3120995982"; google_ad_width = 160; google_ad_height = 600; //--></script> <script type="text/javascript" src="<[login to view URL]>"> </script> <script type="text/javascript"><!--// <![CDATA[ google_ad_client = "pub-3153097597200094"; /* 468x60, created 3/5/08 Pascal */ google_ad_slot = "3756691810"; google_ad_width = 468; google_ad_height = 60; //--> </script> <script type="text/javascript" src="<[login to view URL]>"> </script> <script type="text/javascript" src="[[login to view URL]"></script][1]> <div class="adsense250 right"><script type="text/javascript"><!-- google_ad_client = "pub-8678763012128123"; google_ad_slot = ""; google_ad_width = 250; google_ad_height = 250; </script> <script type="text/javascript" src="[[login to view URL]"></script></div][1]> <script type="text/javascript"><!-- google_ad_client = "pub-4693662170792965"; google_ad_width = 120; google_ad_height = 600; google_ad_format = "120x600_as"; google_ad_channel =""; google_ad_type = "text"; google_color_border = "006699"; google_color_bg = "ECF8FF"; google_color_link = "0000CC"; google_color_url = "008000"; google_color_text = "6F6F6F"; //--></script>&nbsp;<script type="text/javascript" src="<[login to view URL]>"> </script> <div style="text-align: center;margin: 5px;"><script type="text/javascript"> google_ad_client = "pub-9794464753711083"; google_alternate_color = "FFFFFF"; google_ad_width = 468; google_ad_height = 60; google_ad_format = "468x60_as"; google_ad_type = "text_image"; google_ad_channel =""; google_color_border = "#000000"; google_color_link = "#FFFFCC"; google_color_bg = "#940C0E"; google_color_text = "#FFCC66"; google_color_url = "#E6E6E6"; google_ui_features = "rc:10"; //--> </script> <script type="text/javascript" src="<[login to view URL]>"> </script></div><p> <script type="text/javascript">google_ad_client = "pub-7676581854075673";/* 300x250, Erstellt 11.11.10 */google_ad_slot = "7343419665";google_ad_width = 300;google_ad_height = 250;</script><script type="text/javascript" src="<[login to view URL]>"> </script> That's it! :-) Thank you!
