ya tengo todo cluster, ahora lo q quisiera q me ayudaras es el lo siguiente:
el script q consegui originalmente muestra todo ,osea, el titulo y el contenido completo de la noticia, lo unico q quiero es q muestre solo los titulares, ya lo modifique y logre q solo muestre los titulares pero ahora el problema y ahi si no se como hacerle hasta ahora es q me deje por lo menos una linea entre titular y titular y poder restringir el numero de tutilares a mostrar, osea, no los quiero mostrar todos porq son demasiados y descuadraria la página...
En mi archivo donde quiero mostrar estas noticias hago un include de la siguiente manera:
Inicio.php
Código PHP:
<?php
include_once("XmlParser.class.php");
$FeedUrl="http://www.rnv.gov.ve/noticias/index.php?act=ShowRSS";
$XMLpar = new SimpleXmlParser($FeedUrl);
?>
El archivo q estoy incluyendo es XmlParser.class.php
Código PHP:
<?php
class SimpleXmlParser{
// @ Variable Holding Parser
var $SimpleParser;
//@ Feed Source URL
var $feedUrl;
//@ Variables to Hold the Data
var $title = "";
var $description = "";
var $link = "";
var $author="";
var $pubDate="";
var $insideitem = false;
var $tag = "";
// Purpose : Constructor, Which will initialize the XML Parser
function SimpleXmlParser($MyFeed){
//To begin, I create an instance of the XML parser
$this->SimpleParser = xml_parser_create(); // creates a new XML parser and returns a reousurce handle referencing
$this->feedUrl=$MyFeed; // Assigns the Feed Source to the Member Variable
xml_set_object($this->SimpleParser,&$this); // allows to use parser inside object
xml_set_element_handler($this->SimpleParser, "XmlParserFirstElement", "XmlParserendElement"); // Sets the element handler functions for the XML parser parser
xml_set_character_data_handler($this->SimpleParser, "characterData"); // Sets the character data handler function for the XML parser parser
$this->ParseFeed(); // Call to Parser Function
}
function XmlParserFirstElement($parser, $tagName, $attrs) {
//The Function Will be called, when ever the XML_PARSER Encounters a start Tag, in the XML File
if ($this->insideitem) {
$this->tag = $tagName;
} elseif ($tagName == "ITEM") {
$this->insideitem = true;
}
}
function XmlParserendElement($parser, $tagName) {
//The Function Will be called, when ever the XML_PARSER Encounters a end Tag, in the XML File
if ($tagName == "ITEM") {
printf("<dt><b><a href='%s'>%s</a></b></dt>",
trim($this->link),htmlspecialchars(trim($this->title))); //Display the Title Element from the XML file to HTML
// Description element is made to display in HTML. AQUI LE ELIMINE EL CONTENIDO
// Deallocation of all Global Variables
$this->title = "";
$this->description = "";
$this->link = "";
$this->insideitem = false;
}
}
//Function will be called by the Parser when the end tage of the element is processed. Requires Two Permeters
function characterData($parser, $data) {
//Permeters: the parser instance and the string containing the data.
if ($this->insideitem) {
switch ($this->tag) {
case "TITLE":
$this->title .= $data;
break;
case "DESCRIPTION":
$this->description .= $data;
break;
case "LINK":
$this->link .= $data;
break;
}
}
}
function ParseFeed(){
// This is the Place we need to Do error Handling for the XML file, which is not done in this class
$fp = fopen($this->feedUrl,"r") // Open the XML file for reading.
or die("Oops!!! Unexpected Error While Reading the Feed"); // This part will be executed when we compiler is Unable to Open the XML Feed
//Starts reading the contents of the file, 4K at a time, and put it in the variable “$data”
while ($data = fread($fp, 4096)){
xml_parse($this->SimpleParser, $data, feof($fp));
}
//Perform Some Clean Up Work Before Closing the File.
//Closing the XML File
fclose($fp);
//Release the XML Parser
xml_parser_free($this->SimpleParser);
}
}
?>
Gracias..
