I have some basic code with which I am trying to select a data element from a document.

I cannot figure out what I'm doing wrong why it is only returning null values.


import org.jdom.input.SAXBuilder;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.xpath.XPath;
import org.jdom.output.XMLOutputter;
import com.boomi.execution.ExecutionUtil;
logger = ExecutionUtil.getBaseLogger();
InputStream is = dataContext.getStream(0);
Properties props = dataContext.getProperties(0);

// Build XML Document
SAXBuilder builder = new SAXBuilder();
Document doc =;
XMLOutputter xmOut = new XMLOutputter();

logger.warning("DOC + " + xmOut.outputString(doc));

XPath xMatrixManager = XPath.newInstance("//person");
XPath xManagerID = XPath.newInstance("//manager_id");

// Select a single node and grab the actual value
matrixManagerElement = xMatrixManager.selectSingleNode(doc);
managerIDElement = xManagerID.selectSingleNode(doc);




Both elements are returning null.


The XML (with PII removed) returned when I output doc is:


<?xml version="1.0" encoding="UTF-8"?>
<person xmlns="">
