Como un feed<\/em> no es m\u00e1s que un documento XML<\/abbr>, podemos recorrerlo gracias a las extensiones de DOM<\/abbr> de PHP<\/abbr><\/a>.<\/p>\n

B\u00e1sicamente lo que hay que hacer es asignar a una variable un nuevo DomDocument<\/code> en el que cargamos el feed<\/em>, despu\u00e9s s\u00f3lo hay que obtener una lista de los nodos que contienen la informaci\u00f3n de las entradas, y por \u00faltimo crear un bucle que extraiga los datos que nos interesan y cree el marcado que queremos mostrar en la p\u00e1gina:<\/p>\n

<ul>\r\n<?php\r\n$xml = new DomDocument();\r\n$xml->load('http:\/\/la-url-del-blog\/?feed=rss2');\r\n$raiz = $xml->documentElement;\r\n$entradas = $raiz->getElementsByTagName('item');\r\nfor($i=0;$i<10;$i++){\r\n\u00a0\u00a0 \u00a0$titulo = $entradas->item($i)->getElementsByTagName('title')->item(0)->nodeValue;\r\n\u00a0\u00a0 \u00a0$vinculo = $entradas->item($i)->getElementsByTagName('link')->item(0)->nodeValue;\r\n\u00a0\u00a0 \u00a0$fecha = $entradas->item($i)->getElementsByTagName('pubDate')->item(0)->nodeValue;\r\n\u00a0\u00a0 \u00a0$fecha_unix = strtotime($fecha);\r\n\u00a0\u00a0 \u00a0$fecha = strftime(\"%d\/%m\/%Y\",$fecha_unix);\r\n\u00a0\u00a0 \u00a0echo '<li><a href=\"'.$vinculo.'\">'.$titulo.'<\/a> '.$fecha.'<\/li>';\r\n}\r\n?>\r\n<\/ul><\/pre>\n
