regex - How to parse <a name and <image src= inside <li tag using php? -
i got html string lots of <li> .. </li> sets. want parse following data each set of <li> ...</li> :
1: call.php?category=fruits&fruitid=123456 2: mango season 3: http://imagehosting.com/images/fru_123456.png i used preg_match_all first value how second , third value ? happy if show me second , third item .thanks in advance.
php:
preg_match_all('/getit(.*?)detailfruit/', $code2, $match); var_dump($match); // iterate new array for($i = 0; $i < count($match[0]); $i++) { $code3=str_replace('getit(\'', '', $match[0]); $code4=str_replace('&\',detailfruit', '', $code3); echo "<br>".$code4[$i]; } sample <li> ..</li> data:
<li><a id="fr123456" onclick="setfood(false);setseasonfruitid('123456');getit('call.php?category=fruits&fruitid=123456&',detailfruit,false);">mango season</a><img src="http://imagehosting.com/images/fru_123456.png"> </li> edit: used dom got 2 , 3 value how first value using dom ?
libxml_use_internal_errors(true); $dom = new domdocument; $dom->loadhtml($code2); $xpath = new domxpath($dom); // empty array hold links return $result = array(); //loop through each <li> tag in dom foreach($dom->getelementsbytagname('li') $li) { //loop through each <a> tag within li, extract node value foreach($li->getelementsbytagname('a') $links){ $result[] = $links->nodevalue; echo $result[0] . "\n"; } $imgs = $xpath->query("//li/img/@src"); foreach ($imgs $img) { echo $img->nodevalue . "\n"; } }
interesting question :-) following solution uses combination of domdocument/simplexml values 2 & 3 easily. domdocument used html snippet corrupted. link (value 1) javascript content, simple regex used:
~getit\('([^']+)'\)~ # search getit( , singlequote literally # capture (but not including) new single quote # saved in group 1 a complete walkthrough can found below (obviously made banana part):
<?php $html = '<ul> <li><a id="fr123456" onclick="setfood(false);setseasonfruitid(\'123456\');getit(\'call.php?category=fruits&fruitid=123456&\',detailfruit,false);">mango season</a><img src="http://imagehosting.com/images/fru_123456.png"></li> <li><a id="fr7890" onclick="setfood(false);setseasonfruitid(\'7890\');getit(\'call.php?category=fruits&fruitid=7890&\',detailfruit,false);">bananas</a><img src="http://imagehosting.com/images/fru_7890.png"></li> </ul>'; $dom = new domdocument; $dom->stricterrorchecking = false; $dom->loadhtml($html); $xml = simplexml_import_dom($dom); # xpath find list items $items = $xml->xpath("//ul/li"); $regex = "~getit\('([^']+)'\)~"; # loop on items foreach ($items $item) { $title = $item->a->__tostring(); $imglink = $item->img["src"]; $jslink = $item->a["onclick"]; preg_match_all($regex, $jslink, $matches); $jslink = $matches[1][0]; echo "title: $title, imglink: $imglink, jslink: $jslink\n"; // output: title: mango season, imglink: http://imagehosting.com/images/fru_123456.png, jslink: call.php?category=fruits&fruitid=123456& // title: bananas, imglink: http://imagehosting.com/images/fru_7890.png, jslink: call.php?category=fruits&fruitid=7890& } ?>
