How Powerful Is Your StAX Parser?
This tip is a simple application that demonstrates the possibilities of your StAX parser by setting the XMLInputFactory properties to true/false. The StAX parser tested in this example is the BEA and JCP parser.

import javax.xml.stream.*;
public class XMLInputFactoryProperties{
public static void main(String[] args)
{
String[] properties={"javax.xml.stream.isValidating",
"javax.xml.stream.isNamespaceAware",
"javax.xml.stream.isCoalescing","javax.xml.stream.isReplacingEntityReferences",
"javax.xml.stream.isSupportingExternalEntities","javax.xml.stream.supportDTD"};
XMLInputFactory XMLif=null;
System.setProperty("javax.xml.stream.XMLInputFactory","com.bea.xml.stream.MXParserFactory");
//get an XMLInputFactory instance
XMLif=XMLInputFactory.newInstance();
//testing
System.out.println("Case 1:");
for(int i=0;i<properties.length;i++)
{
try{
XMLif.setProperty(properties[i],Boolean.TRUE);
System.out.println("---OK-"+properties[i]+"-OK---\n");
}catch(java.lang.IllegalArgumentException e)
{
System.out.println("---NO-"+properties[i]+"-NO---");
System.out.println(e.getMessage()+"\n");
}
}
System.out.println("Case 2:");
for(int i=0;i<properties.length;i++)
{
try{
XMLif.setProperty(properties[i],Boolean.FALSE);
System.out.println("---OK-"+properties[i]+"-OK---\n");
}catch(java.lang.IllegalArgumentException e)
{
System.out.println("---NO-"+properties[i]+"-NO---");
System.out.println(e.getMessage()+"\n");
}
}
}
}

If you have a hot tip and we publish it, we'll pay you. However, due to accounting overhead we no longer pay $10 for a single tip submission. You must accumulate 10 acceptable tips to receive payment. Be sure to include a clear explanation of what the technique does and why it's useful. If it includes code, limit it to 20 lines if possible. Submit your tip here.
