How to look for spaces in an extract file in order to trigger a MOVE_IT rule

Question

In studio I am defining a variable field on a section and I want to pull information from my extract file using a simple MOVE_IT rule. 
I am trying to pull information from a record that has spaces in columns 10-14.  How do I enter the information required in the DATA field to request this? 
For example, if I was pulling the information from a record that had "XXXXX" in column 10-14 I know the DATA field would be 10,XXXXX
I cant seem to figure out how to look for spaces at a particular offset.
Thanks.

Using XPath to locate the elements you are after is very easy.
Try something like this:
import java.io.File;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathFactory;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;
public class BasicXMLReplaceWithDOM4J {
     static String inputFile = "C:/student.xml";
     static String outputFile = "C:/studentRenamed.xml";
     public static void main(String[] args) throws Exception {
          // Read xml and build a DOM document
          Document doc = DocumentBuilderFactory.newInstance()
                    .newDocumentBuilder().parse(new InputSource(inputFile));
          // Use XPath to find all nodes where student is named 'Suresh'
          XPath xpath = XPathFactory.newInstance().newXPath();
          NodeList nodes = (NodeList)xpath
               .evaluate("//stud_name[text()='Suresh']", doc, XPathConstants.NODESET);
          // Rename these nodes
          for (int idx = 0; idx < nodes.getLength(); idx++) {
               nodes.item(idx).setTextContent("Suresh-Renamed");
          // Write the DOM document to the file
          Transformer xformer = TransformerFactory.newInstance().newTransformer();
          xformer.transform(new DOMSource(doc), new StreamResult(new File(outputFile)));
