filter paragraphs from a XML using PHP and HTMLPurifier, SimpleXmlElement or DOM -
i'm trying remove social media buttons, leaving paragraphs, description field of xml here (it's big post here).
edit: since of couldn't access xml, follow part of 1 of description tags:

here how did @ end (following puggan se's suggestion):
$i=0; $feed= '<xml string>'; //the whole xml string here $dom = new domdocument(); //declaring domdocument $dom->preservewhitespace = false; //removing spaces $dom->loadxml($feed, libxml_parsehuge); //libxml_parsehuge long xmls $dom->formatoutput = true; // nice output ?? $xml = new domxpath($dom); //declaring xpath $xml->registernamespace('a','http://purl.org/dc/elements/1.1/'); //getting namespace xml //evaluates $source = $xml->evaluate("//channel/title"); $titles = $xml->evaluate("//item/title"); $links = $xml->evaluate("//item/link"); $dates = $xml->evaluate("//item/dc:date"); $descriptions = $xml->evaluate("//item/description"); //echoing channel's title if($source->length > 0) { $source= $source->item(0)->nodevalue; echo $source. '<br /><br />'; } //echoing items foreach($titles $title) { echo "{$titles->item($i)->nodevalue}<br /><br />"; echo "{$links->item($i)->nodevalue}<br /><br />"; echo "{$dates->item($i)->nodevalue}<br /><br />"; //filtering <p><span> text <description> $description = "{$descriptions->item($i)->nodevalue} "; $description = mb_convert_encoding($conteudo, 'html-entities', 'utf-8'); unset($domtmp); $domtmp = new domdocument(); $domtmp->loadhtml($description ); $xmltmp = new domxpath($domtmp); $desc= $xmltmp->evaluate("//p/span"); foreach($desc $node) { echo "<p>{$node->nodevalue}</p>"; } $i++; } do know how improve it?
thank much, help!
