I have an XML as Java String:
String abc = "<Tags Value = '635' Type = 'Number'/>";
I am trying to extract the Value
of such an XML object using Xpath
What I tried until now is something like this:
InputSource doc = new InputSource(abc);
XPath xPath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xPath.compile("/Tags[@Value]");
System.out.println(expr.evaluate(doc));
InputSource doc = new InputSource(abc);
XPath xPath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xPath.compile("/Tags/@Value");
System.out.println(expr.evaluate(doc));
try it
public class Example {
public static void main(String[] args) throws FileNotFoundException, XPathExpressionException {
String abc = "<Tags Value = '635' Type = 'Number'/>";
InputSource doc = new InputSource(new StringReader(abc));
XPath xPath = XPathFactory.newInstance().newXPath();
XPathExpression expr = xPath.compile("/Tags/@Value");
System.out.println(expr.evaluate(doc)); // 635
}
}
