i have huge html document has different tables unique table ids. like:
<table class="my_table" id="table_id1"> <tr class="odd"><td>line 1</td></tr> <tr class="even"><td>line 2</td></tr> <tr class="odd"><td>line 3</td></tr> <tr class="even"><td>line 4</td></tr> </table> <table class="my_table" id="table_id2"> <tr class="odd"><td>line 1</td></tr> <tr class="even"><td>line 2</td></tr> <tr class="odd"><td>line 3</td></tr> </table> is possible using preg_match find html of rows of specific table?
i tried following code:
preg_match('/<table[^>]*id="table_id2">(<tr[^>]*><td>[^>]*<\/td><\/tr>)+/', $html, $matches); //$html variable contains html. but returns output like:
array ( [0] => array ( [0] => <table class="my_table" id="table_id2"><tr class="odd"><td>line 1</td></tr><tr class="even"><td>line 2</td></tr><tr class="odd"><td>line 3</td></tr> ) [1] => array ( [0] => <tr class="odd"><td>line 3</td></tr> ) ) but need output this:
array ( [0] => array ( [0] => <table class="my_table" id="table_id2"><tr class="odd"><td>line 1</td></tr><tr class="even"><td>line 2</td></tr><tr class="odd"><td>line 3</td></tr> ) [1] => array ( [0] => <tr class="odd"><td>line 1</td></tr> [1] => <tr class="odd"><td>line 2</td></tr> [2] => <tr class="odd"><td>line 3</td></tr> ) ) is possible? please help.
you should not use regex parsing html. php has great tool - domdocument. using it, can many things, impossible/near impossible regex. sample like:
$shtml = '<table class="my_table" id="table_id1"> <tr class="odd"><td>line 1</td></tr> <tr class="even"><td>line 2</td></tr> <tr class="odd"><td>line 3</td></tr> <tr class="even"><td>line 4</td></tr> </table> <table class="my_table" id="table_id2"> <tr class="odd"><td>line 1</td></tr> <tr class="even"><td>line 2</td></tr> <tr class="odd"><td>line 3</td></tr> </table>'; $rdoc = new domdocument(); $rdoc->loadhtml($shtml); $sid = 'table_id2'; //found table: $rtable = $rdoc->getelementbyid($sid); foreach($rtable->childnodes $ritem) { //do item: //var_dump($ritem); }
