Hi,
I am getting parsing error in xpath transformation


String s = "if (/blah/text()!='') then blah/text() else ''";
XPathExpression expression = xpath.compile(s);

Object o = expression.evaluate(target, XPathConstants.NODESET);

I am using normal core java and xml packages to parse
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathExpression;
import javax.xml.xpath.XPathFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Node;

import org.w3c.dom.NodeList;


Exception:
