Example 3

The following htmlTable.xml file has CDATA section. We need to parse this XML file.

<htmlTable>
<![CDATA[         <table>]]> - HTML table tag.
</htmlTable>

The Java getTextTrim() method returns CDATA section if available inside the XML element.

import java.io.File;
import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.input.SAXBuilder;

public class GetTextContent {
   public static void main(String args[]) {
      try {	
    	 //Reading the document
    	 SAXBuilder saxBuilder = new SAXBuilder();
    	 File inputFile = new File("htmlTable.xml");
    	 Document doc = saxBuilder.build(inputFile);
	     //Get the root
	     Element root = doc.getRootElement();
	     //Get text content
	     String textContent = root.getTextTrim();
	     System.out.println("Text Content: "+textContent);       
      } catch (Exception e) {
    	 e.printStackTrace();
      }
   }
}

The trimmed text content along with CDATA section is displayed.

Text Content: <table> - HTML table tag.
