DoctypeInterpolator (Starjava TTOOLS API)

java.lang.Object
- uk.ac.starlink.ttools.votlint.DoctypeInterpolator

```
public class DoctypeInterpolator
extends java.lang.Object
```
Attempts to check that a DOCTYPE declaration is present in an input stream representing XML. If it is not, one is inserted. The algorithm used here isn't bulletproof, but should work in most sensible cases, and fail noisily if it can't do it. It copes with a number of not-too-weird XML encodings.
