Hi Gurus,
I have an importstructure which can be enhanced dynamiccaly hence not all fields are defined and available in the mapping. Now there is a field which is not defined in the importstructure that contains a value I want to read.
I'm trying to create an UDF which reads a value from a structure dynamically. The path of this field is given as an inputparameter (KVK).
public String Bepaal(Container container) throws StreamTransformationException{
Document doc = null;
String value = null;
try { String inParam = container.getInputParameters().getString("KVK"); //Bouw document op o.b.v. intpustream DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(false); DocumentBuilder builder = factory.newDocumentBuilder(); doc = builder.parse(<How do I get the inputstream??>); //Bouw xpath expressie t.b.v. het ophalen van de base64 gecodeerde waarde XPathFactory xFactory = XPathFactory.newInstance(); XPath xpathExpr = xFactory.newXPath(); XPathExpression expr = xpathExpr.compile(inParam); Object result = expr.evaluate(doc, XPathConstants.NODESET); //Bepaal gevonden node(s) en bepaal de waarde van de eerstgevonden waarde in de lijst NodeList nlList = (NodeList) result; value = nlList.item(0).getNodeValue();
}
catch (Exception e) { container.getTrace().addWarning(e.toString()); return "";
}
return value;
}
return value
;The problem is, how do I get the inputstream? I only have a container element.
