使用php根据xsd验证xml文件

how to validate a xml file against a xsd? there is domdocument::schemaValidate() but It does not tell where are the errors. is there any class for that? does it have any worth making that parser from scratch? or is it just reinventing he wheel,

如何根据xsd验证xml文件?有domdocument::schemaValidate()，但它不知道错误在哪里。有这方面的课程吗?是否有必要从头开始创建解析器?或者只是重新发明*，

This code does the business:

这个代码的业务是:

$xml= new DOMDocument();
$xml->loadXML(<A string goes here containing the XML data>, LIBXML_NOBLANKS); // Or load if filename required
if (!$xml->schemaValidate(<file name for the XSD file>)) // Or schemaValidateSource if string used.
{
   // You have an error in the XML file
}

See the code in http://php.net/manual/en/domdocument.schemavalidate.php To retrieve the errors.

请参阅http://php.net/manual/en/domdocument.schemavalidate.php中的代码，以检索错误。

I.e.

For more detailed feedback from DOMDocument::schemaValidate, disable libxml errors and fetch error information yourself. See http://php.net/manual/en/ref.libxml.php for more info.

有关DOMDocument::schemaValidate的更详细反馈，请禁用libxml错误并自己获取错误信息。更多信息请参见http://php.net/manual/en/ref.libxml.php。
