## DtdProcessing enum


Specifies the options for processing DTDs. The [DtdProcessing](./) enumeration is used by the [XmlReaderSettings](../xmlreadersettings/) class.

```cpp
enum class DtdProcessing
```

### Values

| Name | Value | Description |
| --- | --- | --- |
| Prohibit | 0 | Specifies that when a DTD is encountered, an [XmlException](../xmlexception/) is thrown with a message that states that DTDs are prohibited. This is the default behavior. |
| Ignore | 1 | Causes the DOCTYPE element to be ignored. No DTD processing occurs, and the DTD/DOCTYPE is lost on output. |
