然后我需要把然后在另一个XML文件：第一个进入“艺术家”，第二个进入“称号”。例如：

块引用

<?xml version="1.0" encoding="UTF-8"?> 
<allchannels count="1"> 
<ilr_trackinfo channel="1"> 
<artist> 
<![CDATA[ Post Malone ]]> 
</artist> 
<title> 
<![CDATA[ Congratulations (feat. Quavo) ]]> 
</title> 
<image src="http://95.154.254.129:17618/playingart?sid=1"/> 
</ilr_trackinfo> 
</allchannels> 

“ilr_trackinfo通道=” 1 “”， “allchannels计数=” 1 “”， “图像” 是静态的。 这可能吗？

下面是一个例子：

<?php 

$songs = []; 

$channels = range(1,3); 

// Download current songs (from 1 to 3) 
foreach ($channels as $sid) { 
    $song = file_get_contents(sprintf('http://95.154.254.129:17618/currentsong?sid=%s', $sid)); 
    list($artist, $title) = explode('-', $song, 2); 
    $songs[] = [ 
     'sid' => $sid, 
     'image' => sprintf('http://95.154.254.129:17618/playingart?sid=%s', $sid), 
     'song' => $song, 
     'artist' => trim($artist), 
     'title' => trim($title) 
    ]; 
} 
unset($song); 
//print_r($songs); 

// Write new xml file 
$doc = new DOMDocument('1.0', 'UTF-8'); 
$doc->preserveWhiteSpace = false; 
$doc->formatOutput = true; 

$allChannels = $doc->createElement("allchannels"); 
$allChannels->setAttribute('count' , count($channels)); 
$doc->appendChild($allChannels); 

$trackInfo = $doc->createElement("ilr_trackinfo"); 
$trackInfo->setAttribute('channel' , $song['sid']); 

foreach ($songs as $song) { 
    $trackInfo = $doc->createElement("ilr_trackinfo"); 
    $trackInfo->setAttribute('channel' , $song['sid']); 
    $allChannels->appendChild($trackInfo); 

    $artist = $doc->createElement("artist"); 
    $trackInfo->appendChild($artist); 

    $artistCdata = $doc->createCDATASection($song['artist']); 
    $artist->appendChild($artistCdata); 

    $title = $doc->createElement("title"); 
    $trackInfo->appendChild($title); 

    $titleCdata = $doc->createCDATASection($song['title']); 
    $title->appendChild($titleCdata); 

    $image = $doc->createElement("image"); 
    $image->setAttribute('src', $song['image']); 
    $trackInfo->appendChild($image); 
} 

header("Content-type: text/xml"); 
echo $doc->saveXML();
