[英]validate a xml file against a xsd using php
how to validate a xml file against a xsd?如何根据 xsd 验证 xml 文件? there is domdocument::schemaValidate() but It does not tell where are the errors.
有 domdocument::schemaValidate() 但它没有告诉错误在哪里。 is there any class for that?
有什么课程吗? does it have any worth making that parser from scratch?
从头开始制作该解析器是否值得? or is it just reinventing he wheel,
或者只是重新发明他的轮子,
This code does the business:此代码执行以下操作:
$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。

For more detailed feedback from DOMDocument::schemaValidate, disable libxml errors and fetch error information yourself.
如需来自 DOMDocument::schemaValidate 的更详细反馈,请禁用 libxml 错误并自行获取错误信息。 See http://php.net/manual/en/ref.libxml.php for more info.
有关详细信息,请参阅http://php.net/manual/en/ref.libxml.php 。

This is a complete code snippet for displaying xsd validation errors:这是显示 xsd 验证错误的完整代码片段:
$xml = '<test/>';
$xsd = '/path/to/xsd';
// needed for getting errors
libxml_use_internal_errors(true);
$domDocument= new DOMDocument();
$domDocument->loadXML($xml);
if (!$domDocument->schemaValidate($xsd)) {
$errors = libxml_get_errors();
foreach ($errors as $error) {
print_r($error);
}
libxml_clear_errors();
}
