Problema con saltos de linea de XML en PHP 
.Llevo mucho tiempo buscando una solución para este problema y no la he podido encontrar.
Intento sacar el contenido de un archivo XML para mostrarlo en un web. En concreto, quiero obtener letras de canciones a través de la API de lyricwiki.org.
Llevo poco tiempo programando en PHP, por eso busqué algun código ya realizado para obtener los datos de XML, y lo adapté a mis necesidades:
Código PHP:
<?php
$myFile="h t t p : / / lyricwiki . o r g /api.php?artist=$artista&song=$nom&fmt=xml";
$theData = file_get_contents($myFile);
$xml=( xml2array($theData));
print '<p>';
print("\n".$xml['LyricsResult']['lyrics']['value']);
print '</p>';
$xml = ereg_replace("<br>","\r",$acti);
function xml2array($contents, $get_attributes=1) {
if(!$contents) return array();
if(!function_exists('xml_parser_create')) {
//print "'xml_parser_create()' function not found!";
return array();
}
//Get the XML parser of PHP - PHP must have this module for the parser to work
$parser = xml_parser_create();
xml_parser_set_option( $parser, XML_OPTION_CASE_FOLDING, 0 );
xml_parser_set_option( $parser, XML_OPTION_SKIP_WHITE, 1 );
xml_parse_into_struct( $parser, $contents, $xml_values );
xml_parser_free( $parser );
if(!$xml_values) return;//Hmm...
//Initializations
$xml_array = array();
$parents = array();
$opened_tags = array();
$arr = array();
$current = &$xml_array;
//Go through the tags.
foreach($xml_values as $data) {
unset($attributes,$value);//Remove existing values, or there will be trouble
extract($data);//We could use the array by itself, but this cooler.
$result = '';
if($get_attributes) {//The second argument of the function decides this.
$result = array();
if(isset($value)) $result['value'] = $value;
//Set the attributes too.
if(isset($attributes)) {
foreach($attributes as $attr => $val) {
if($get_attributes == 1) $result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr'
/** :TODO: should we change the key name to '_attr'? Someone may use the tagname 'attr'. Same goes for 'value' too */
}
}
} elseif(isset($value)) {
$result = $value;
}
//See tag status and do the needed.
if($type == "open") {//The starting of the tag '<tag>'
$parent[$level-1] = &$current;
if(!is_array($current) or (!in_array($tag, array_keys($current)))) { //Insert New tag
$current[$tag] = $result;
$current = &$current[$tag];
} else { //There was another element with the same tag name
if(isset($current[$tag][0])) {
array_push($current[$tag], $result);
} else {
$current[$tag] = array($current[$tag],$result);
}
$last = count($current[$tag]) - 1;
$current = &$current[$tag][$last];
}
} elseif($type == "complete") { //Tags that ends in 1 line '<tag />'
//See if the key is already taken.
if(!isset($current[$tag])) { //New Key
$current[$tag] = $result;
} else { //If taken, put all things inside a list(array)
if((is_array($current[$tag]) and $get_attributes == 0)//If it is already an array...
or (isset($current[$tag][0]) and is_array($current[$tag][0]) and $get_attributes == 1)) {
array_push($current[$tag],$result); // ...push the new element into that array.
} else { //If it is not an array...
$current[$tag] = array($current[$tag],$result); //...Make it an array using using the existing value and the new value
}
}
} elseif($type == 'close') { //End of tag '</tag>'
$current = &$parent[$level-1];
}
}
return($xml_array);
} Código PHP:
h t t p : / / lyricwiki . o r g /api.php?artist=$artista&song=$nom&fmt=xml
h t t p : / / lyricwiki . o r g /api.php?artist=Coldplay&song=Clocks&fmt=xml
Hasta aquí, todo va bien. El problema es que el código XML tiene saltos de línea, y al cargar los datos por php se pierden.
¿Alguien conoce alguna solución?
