Method

StringgetValueByXPath(Document document, String xpath)
Get a value by xpath. 
String value = "";
try {
    value = xPathFactory.newXPath().evaluate(xpath, document).trim();
} catch (Exception e) {
return value;
intgetValueByXPathAsInt(Document document, String xpath)
Get a value by xpath and return as an int. 
int x = 0;
try {
    x = Integer.parseInt(getValueByXPath(document, xpath));
} catch (Exception e) {
return x;
StringgetValueFromXPath(Document document, String xpathString)
Returns the string value of evaluated xpath
