SAXHandler (zk 8.5.1 API)

java.lang.Object
- org.xml.sax.helpers.DefaultHandler
- - org.zkoss.idom.input.SAXHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.ext.DeclHandler, org.xml.sax.ext.LexicalHandler
```
public class SAXHandler
extends org.xml.sax.helpers.DefaultHandler
implements org.xml.sax.ext.LexicalHandler, org.xml.sax.ext.DeclHandler
```
The SAX Handler. It implements ContentHandler, LexicalHandler and DeclHandler. It is the caller's job to set up this handler properly if required.
This class doesn't depend on SAXBuilder, so it can be used in any other place, e.g., javax.xml.transform.sax.SAXResult.

- Method Detail
  - isIgnoringElementContentWhitespace
```
public final boolean isIgnoringElementContentWhitespace()
```
    Tests whether to ignore whitespaces in element content.
  - setIgnoringElementContentWhitespace
```
public final void setIgnoringElementContentWhitespace(boolean ignore)
```
    Sets whether the parser should eliminate whitespace in element content. They are known as "ignorable whitespace". Only whitespace which is contained within element content that has an element only content model will be eliminated (see XML Rec 2.10).
    For this setting to take effect requires that validation be turned on.
    Default: false.
    
    Parameters:
    
    ignore - Whether to ignore whitespaces in element content.
