public class HTMLScanner
extends Object
implements XMLDocumentSource, XMLLocator, HTMLComponent
```
A simple HTML scanner. This scanner makes no attempt to balance tags or fix other problems in the source document — it just scans what it can and generates XNI document "events", ignoring errors of all kinds.
This component recognizes the following features:

- Method Detail
  - pushInputSource
```
public void pushInputSource(XMLInputSource inputSource)
```
    Pushes an input source onto the current entity stack. This enables the scanner to transparently scan new content (e.g. the output written by an embedded script). At the end of the current entity, the scanner returns where it left off at the time this entity source was pushed.
    Note: This functionality is experimental at this time and is subject to change in future releases of NekoHTML.
    
    Parameters:
    
    inputSource - The new input source to start scanning.
    
    See Also:
    
    evaluateInputSource(XMLInputSource)
  - evaluateInputSource
```
public void evaluateInputSource(XMLInputSource inputSource)
```
    Immediately evaluates an input source and add the new content (e.g. the output written by an embedded script).
    
    Parameters:
    
    inputSource - The new input source to start evaluating.
    
    See Also:
    
    pushInputSource(XMLInputSource)
  - cleanup
```
public void cleanup(boolean closeall)
```
    Cleans up used resources. For example, if scanning is terminated early, then this method ensures all remaining open streams are closed.
    
    Parameters:
    
    closeall - Close all streams, including the original. This is used in cases when the application has opened the original document stream and should be responsible for closing it.
