PHP DomDocument::schemaValidateSource方法代码示例

 /**
  * That validate function takes an XSD to valid against `$this->_xml`
  * returning boolean. Optionally, a second parameter `$xml` can be
  * passed that will be used instead of `$this->_xml`.
  *
  * @since Symphony 2.3
  * @param string $xsd
  *  The XSD to validate `$this->_xml` against
  * @param string $xml (optional)
  *  If provided, this function will use this `$xml` instead of
  *  `$this->_xml`.
  * @return boolean
  *  Returns true if the `$xml` validates against `$xsd`, false otherwise.
  *  If false is returned, the errors can be obtained with `XSLTProcess->getErrors()`
