## XmlValidatingReader class


Represents a reader that provides document type definition (DTD), XML-Data Reduced (XDR) schema, and XML [Schema](../../system.xml.schema/) definition language (XSD) validation.

```cpp
class XmlValidatingReader : public System::Xml::XmlReader,
                            public System::Xml::IXmlLineInfo,
                            public System::Xml::IXmlNamespaceResolver
```

## Typedefs

| Typedef | Description |
| --- | --- |
| [Ptr](./ptr/) | An alias for shared pointer to an instance of this class. |
## Remarks


## Deprecated
This class is obsolete. It is recommended to use the XmlReaderSettings class and the XmlReader::Create method to create a validating XML reader. 

Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instances of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.
