Examples of net.sf.saxon.s9api.XPathSelector.evaluate()

net.sf.saxon.s9api.XPathSelector.evaluate()

Evaluate the expression, returning the result as an XdmValue (that is, a sequence of nodes and/or atomic values).

Note: Although a singleton result may be represented as an XdmItem, there is no guarantee that this will always be the case. If you know that the expression will return at most one node or atomic value, it is best to use the evaluateSingle method, which does guarantee that an XdmItem (or null) will be returned.

@return An XdmValue representing the results of the expression. @throws SaxonApiException if a dynamic error occurs during the expression evaluation.


  private static XdmValue evaluate(XPathExecutable exec, XdmNode xdm) throws SaxonApiException {
    Activator.logInfo("Evaluating XPath");
    XPathSelector selector = exec.load();
    selector.setContextItem(xdm);
    return selector.evaluate();
  }


  public static String transformResult(XdmValue xdm, boolean isPrettyPrint) throws Exception {
    Activator.logInfo("Transforming result");

      if (node == null)
        throw new RuntimeException("Found node is not in AST: " + item);
      if (outputBeforeSelector != null) {
        outputBeforeSelector.setContextItem(item);
        outputBeforeSelector.setVariable(CONTEXT_VARIABLE, item);
        valueToInsertBefore = outputBeforeSelector.evaluate().toString();
      }
      result.put(node, valueToInsertBefore);
    }


    return result;
