出于某种原因,iTunes决定将非标准XML格式与其文件一起使用......因此我无法使用SimpleXMLElement阅读它......
iTunes XML示例:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

我遇到了问题,因为如果缺少信息,数组键会不一致。在一个语音中它可能有8个整数值,在另一个语音上它可能有5个......对我来说读这些数据的更好的方法是什么?

这是plist XML file。 Apple使用它们很多。我建议找一个将plist文件解析成适当的本机数据结构的库。 plistParser看起来很有用。
plistParser示例:
<?php
include("PlistParser.inc");
$parser = new plistParser();
$plist = $parser->parse(dirname(__FILE__) . "/iTunes.xml");
var_dump($plist);
?>
输出:
array(8) {
["Major Version"]=>
int(1)
["Minor Version"]=>
int(1)
["Application Version"]=>
string(5) "8.0.1"
["Features"]=>
int(5)
["Show Content Ratings"]=>
bool(true)
["Music Folder"]=>
string(60) "file://localhost/Users/testUser/Music/iTunes/iTunes%20Music/"
["Library Persistent ID"]=>
string(15) "C39203948AF3D3E"
["Tracks"]=>
array(1) {
[1]=>
array(25) {
["Track ID"]=>
int(1)
["Name"]=>
string(8) "My Track"
["Artist"]=>
string(9) "My Artist"
["Album"]=>
string(8) "My Album"
["Genre"]=>
string(8) "My Genre"
["Kind"]=>
string(15) "MPEG audio file"
["Size"]=>
int(123456)
["Total Time"]=>
int(123456)
["Track Number"]=>
int(1)
["Year"]=>
int(2008)
["Date Modified"]=>
string(20) "2008-03-03T03:33:33Z"
["Date Added"]=>
string(20) "2008-03-03T03:33:33Z"
["Bit Rate"]=>
int(128)
["Sample Rate"]=>
int(44100)
["Comments"]=>
string(20) "All Rights Reserved."
["Release Date"]=>
string(20) "2007-03-12T04:01:37Z"
["Persistent ID"]=>
string(14) "C3E339393939E3"
["Track Type"]=>
string(4) "File"
["Podcast"]=>
bool(false)
["Unplayed"]=>
bool(true)
["File Type"]=>
int(123456)
["File Creator"]=>
int(123456)
["Location"]=>
string(66) "file://localhost/Users/testUser/Music/iTunes/iTunes%20Music/my.mp3"
["File Folder Count"]=>
int(4)
["Library Folder Count"]=>
int(1)
}

有点晚了,但是我对我的项目使用了这个确切的建议,我使用了plist解析器近一年。最大的问题是它是一种通用的Plist解析解决方案,非常适合配置和二进制文件,但它不使用数百兆字节的RAM就无法处理大型iTunes库。我最近为php创建了一个基于SAX的解析器,它可以正确地通过iTunes文件流,在每个歌曲条目上提供格式正确的数组。
