cooldude832 Posted November 13, 2007 Share Posted November 13, 2007 I want to use preg_split to split a page about its <div><table><tr><td> tags, so I need a pattern that will match <div> or <table> or <tr>< or <td> any ideas and it has to be able to also handle the fact that a tag could have a styling on it or a class etc Ithink i need something like <div*> but I don't know the rest of it Quote Link to comment Share on other sites More sharing options...
Lumio Posted November 13, 2007 Share Posted November 13, 2007 <?php $code = "Hello\n<div align=\"center\">foo=bar</div>"; $matches = preg_split('/(\<.*?div.*?\>|\<.*?table.*?\>|\<.*?tr.*\>|\<.*?td.*\>)/', $code, -1, PREG_SPLIT_DELIM_CAPTURE); print_r($matches); ?> A thanks would be nice Quote Link to comment Share on other sites More sharing options...

cooldude832 Posted November 13, 2007 Author Share Posted November 13, 2007 that is working great, but now my issue is I somehow have to clear out all the css and all the <script> tags as these are carrying over with junk data. Any ideas? Quote Link to comment Share on other sites More sharing options...
effigy Posted November 13, 2007 Share Posted November 13, 2007 Loop through the array and: 1. Remove <script...>...</script>. 2. Remove style="..." . Quote Link to comment Share on other sites More sharing options...
cooldude832 Posted November 13, 2007 Author Share Posted November 13, 2007 well my first issue was I wanted to remove all the info pre the body tag, I did it using explode, but not all body tags are all lower case, and some had some issues, again a regex issue I tried "\<body*>\"; no good, if you got an idea to do a preg_split at that I'd love to see it, that clears up some of it, but then in body <script> tags also are need to remove, my goal is to strip a page of everythign but container elements (<div>,<table><tr><td>)) whcih that pattern is doing for me, but then also kill all the script/css tags as those are special cases so I guess I need to find a replace ment for <script*>*</script> and <style*>*</style> Quote Link to comment Share on other sites More sharing options...
effigy Posted November 13, 2007 Share Posted November 13, 2007 What about something like this? <pre> <?php $data = <<<DATA <html> <head> <title>Title</title> </head> <body> <font>Font Tag</font> <div>Div Content</div> <div id="1">More Div Content</div> <b>Bold</b> <table> <tr> <td>A Cell</td> </tr> </table> <hr> </body> </html> DATA; ### Split on the begin/end tags of what is desired ### and pull some content along. $matches = preg_split( '%(</?(?:div|t(?:able|[rd]))[^>]*>[^<]*)%', $data, -1, PREG_SPLIT_DELIM_CAPTURE ); ### For each match... $num_matches = count($matches); for ($i = 0; $i < $num_matches; $i++) { ### Strip unwanted tags. $matches[$i] = strip_tags($matches[$i], '<div><table><tr><td>'); ### If the entry doesn't start with a "<" (tag) it wasn't ### included in our split; thus, not desired. if (strpos($matches[$i], '<') !== 0) { unset($matches[$i]); } ### Otherwise, escape it for viewing purposes. else { $matches[$i] = htmlspecialchars($matches[$i]); } } ### Display. print_r($matches); ?> </pre> Quote Link to comment Share on other sites More sharing options...
cooldude832 Posted November 13, 2007 Author Share Posted November 13, 2007 that is working, now I just want to build some sort of multi dimensonal array of the data based on tag depth which I can figrue out, note I subbed back in the < > for the < and > as its easier to type, but i did it post your thing, I'll pm you with the final result if you interested in it.
