Xpath query depenedent on new line chars

Question

Hi,
I am trying to run an XPath query against a String which contains the XML. I am using Apache Commons IOUtils
to convert String to InputStream
If the String contains new line chars in it then I get unexpected results. However if XML is one looong string then there
is no problem.
What can I do to avoid this problem.
     public static void main(String[] args)
               throws XPathFactoryConfigurationException,
               XPathExpressionException, ParserConfigurationException,
               SAXException, IOException {
          // System.out.println(XML);
          XPathFactory xpathFactory = XPathFactory
                    .newInstance(XPathFactory.DEFAULT_OBJECT_MODEL_URI);
          XPath xpath = xpathFactory.newXPath();
          DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance()
                    .newDocumentBuilder();
                // Use XML_STRING as the xml to reproduce the error
          Document document = documentBuilder.parse(IOUtils.toInputStream(XML_STRING));
          NodeList xpathResult = (NodeList) xpath.evaluate("/Envelope/Body",
                    document, XPathConstants.NODESET);
          Node node = xpathResult.item(0).getFirstChild();
          String requestName = node.getNodeName();
          requestName = requestName.split(":",-1)[1];
          System.out.println(requestName);
          String sessionIdXqry = "/Envelope/Body/" + requestName + "/sessionId";
          System.out.println(sessionIdXqry);
          String sessionId = (String)xpath.evaluate(sessionIdXqry, document, XPathConstants.STRING);
          System.out.println("SessionID = " + sessionId);
     }

You can't call methods in EL like that - write a custom tag that transforms the data in the way you want (replacing newlines with "<br>"). Then:
<something:yourNewTag text="${row.description}" />
