用php解析SPML响应文件

我试图解析一个4GB+xml（spml）文件，格式如下。我可以使用SimpleXML解析格式类似的测试文件[当然有一些警告]；但是当我尝试使用XMLReader解析相同的内容时，我没有得到任何输出。如果有人知道任何解决办法，请帮助我

解析4Gb XML可能会导致内存不足，除非您有足够的内存，
您可以使用修复所有格式错误的XML

$ops = array();
$ops['input-xml']  =
$ops['output-xml'] = TRUE;

$tidy = new Tidy($source_file, $ops);
$tidy->isXML();
$tidy->cleanRepair();

// output the fixed xml
ob_start();
echo $tidy;
$buf = ob_get_clean();
file_put_contents($target_file, $buf);

// if you can run from console
// then you can skip the above
// php -q parse.php > new.xml

请在调用XMLReader时添加代码，并说明如何获取输出。否则就很难说了。请重新粘贴您的XML示例，因为没有任何标记是visisble$reader=new XMLReader（）；如果（！$reader->open（“xml_file.xml”）{die（“无法打开文件”）；}如果（！$reader->read（））die（“无法准备”）；虽然（$reader->read（）{die（“sdfsdf”）；}嗯，我在10GB刀片上运行它：），但问题是我想让它更有效率。你能建议最好的方法吗？我已经检查过了，几乎每个人都建议XMLReader用于大文件，尽管它很难处理——我指的是它的代码。不管怎样，我正在尝试你的建议，非常感谢你的回答。嗨，ajreal，我尝试了你整理xml然后阅读的方法。还没有运气。知道吗？哪一部分不走运？新修复的XML是否仍然出现解析错误？确切地说，我仍然收到相同的警告：S

$ops = array();
$ops['input-xml']  =
$ops['output-xml'] = TRUE;

$tidy = new Tidy($source_file, $ops);
$tidy->isXML();
$tidy->cleanRepair();

// output the fixed xml
ob_start();
echo $tidy;
$buf = ob_get_clean();
file_put_contents($target_file, $buf);

// if you can run from console
// then you can skip the above
// php -q parse.php > new.xml
