Edicion de un XML desde un PHP - ayuda u.u Nuestra pagina donde podemos editar el xml:
pagina1.php
Código PHP:
<?php
require dirname(__FILE__).'functions.php';
// get menu.xml file
$p =& new xmlParser();
$p->parse('pagina1.xml');
$settings = $p->output[0]['child'];
?>
<h1>Pagina 1</h1>
<hr />
<table width="700" border="0">

<td width="294" valign="top"><?php
$xml = "";
$f = fopen( 'pagina1.xml', 'r' );
while( $data = fread( $f, 4096 ) ) { $xml .= $data; }
fclose( $f );
preg_match_all( "/\<news\>(.*?)\<\/news\>/s",
$xml, $bookblocks );
foreach( $bookblocks[1] as $block )

preg_match_all( "/\<header\>(.*?)\<\/header\>/",
$block, $header );

?> pagina.xml
Código PHP:
<news>
<header>Don Quijote</header>
<content>Empieza la historia...</content>
<comment>Primer Capitulo</comment>
<author>damian trejo</author>
</news>
El problema de todo, (creo que me excedi de informacion....) es cuando abro pagina1.php, en los campos que me muestran los datos del xml, solamente me muestra a partir del ultimo acento, por ejemplo si pongo: "hola, necesito tener información de un libro", solamente me aparece: "ón de un libro".
Creo que el problema viene de este codigo que aparece en functions:
Código PHP:
function endHandler($parser, $name){
if(count($this->output) > 1) {
$_data = array_pop($this->output);
$_output_idx = count($this->output) - 1;
$this->output[$_output_idx]['child'][] = $_data;
}
Gracias por todo¡¡
