[1919]Using SJSXP to Parse XML Documents
By Anonymous on 2007/08/14 16:28:09  Rate
Reading in XML documents with the SJSXP  ( SUN JAVA STREAMING XML PARSER )  is fairly easy. Most of the work is done through an object that implements the javax.xml.stream.XMLStreamReader interface. This interface represents a cursor that's moved across an XML document from beginning to end. A few things to keep in mind: the cursor always points to a single item, such as an element start-tag, a processing instruction, or a DTD declaration. Also, the cursor always moves forward  ( not backward ) , and you cannot perform any "look aheads" to see what's upcoming in the document. You can obtain an XMLStreamReader to read in XML from a file with the following snippet of code: 
  
  
    URL url = Class.forName ( "MyClassName" ) .getResource (  
            "sample.xml" ) ;             
    InputStream in = url.openStream (  ) ; 
    XMLInputFactory factory = XMLInputFactory.newInstance (  ) ; 
    XMLStreamReader parser = factory.createXMLStreamReader ( in ) ; 
  
  
 You can then iterate through the XML file with the following code: 
  
  
    while ( parser.hasNext (  )  )   {  
               
          eventType = parser.next (  ) ; 
          switch  ( eventType )   {  
  
  
               case START_ELEMENT: 
               // Do something 
               break; 
               case END_ELEMENT: 
               // Do something 
               break; 
               // And so on ... 
           }  
       }  
  
  
 The hasNext (  )  method in XMLStreamReader checks to see if there is another item available in the XML file. If there is one, you can use the next (  )  method to advance the cursor to the next item. The next (  )  method returns an integer code that indicates the type of grammatical construct  ( the item )  that it encountered.
