Class XMLDataExtractor

java.lang.Object

com.identity4j.util.xml.XMLDataExtractor

public class XMLDataExtractor
extends Object

This is a simple utility class which tries to extract node values and attributes from an XML.
This will extract nodes with character value only, a node with children node will result in null.
A node with children or character with attributes will always shows attributes in node instance.
e.g.

 
 <item date="February 2014">
      <mode>2</mode>
      <unit>400</unit>
      <current>2</current>
      <interactive>5</interactive>
 </item>
 
 

When we extract nodes.

• For unit it would extract node value as 400.
• For item it would extract node value as null, as no character data is present, but it will show attributes
