Uccx java xml document NodeList command

[phwang1234]

I am trying to write script for a callback application which will check if the caller has already left a call for a callback recently. 

The xml will be something like

<CallBack>
<Filename>CB.xml</Filename>

<CB>
<DATE>07/02/2020</DATE>
<TIME>12:00</TIME>
<NUM>0400000000</NUM>
<Done>True</Done>
</CB>

<CB>
<DATE>08/02/2020</DATE>
<TIME>11:00</TIME>
<NUM>0288888888</NUM>
<Done>True</Done>
</CB>

<CB>
<DATE>09/02/2020</DATE>
<TIME>13:00</TIME>
<NUM>0388888888</NUM>
<Done>True</Done>
</CB>

<CB>
<DATE>12/02/2020</DATE>
<TIME>12:00</TIME>
<NUM>0400000000</NUM>
<Done>False</Done>
</CB>
</CallBack>

I have this set step

try {
javax.xml.parsers.DocumentBuilderFactory factory = javax.xml.parsers.DocumentBuilderFactory.newInstance();
javax.xml.parsers.DocumentBuilder builder = factory.newDocumentBuilder();
org.w3c.dom.Document domDoc = builder.parse(doc_InputFile);
javax.xml.xpath.XPath XPath = javax.xml.xpath.XPathFactory.newInstance().newXPath();
String XpathEval = str_XPATH;
String RESULT = XPath.evaluate("/CallBack/CB[NUM=0400000000]",domDoc);
return RESULT;
}
catch (java.lang.Exception e) {
e.printStackTrace();
}

But it only returns the first node from the xml.

U"\n\t07/02/2020\n 12:00\n\t0400000000\n\tTrue\n "

So I tried to change it to return a nodelist as below

try {
javax.xml.parsers.DocumentBuilderFactory factory = javax.xml.parsers.DocumentBuilderFactory.newInstance();
javax.xml.parsers.DocumentBuilder builder = factory.newDocumentBuilder();
org.w3c.dom.Document domDoc = builder.parse(doc_InputFile);
javax.xml.xpath.XPath XPath = javax.xml.xpath.XPathFactory.newInstance().newXPath();
String XpathEval = str_XPATH;

NodeList nodeList = (NodeList) xPath.compile("/CallBack/CB[NUM=0400000000]").evaluate(domDoc, XPathConstants.NODESET);
for (int i = 0; i < nodeList.getLength(); i++) {
String RESULT = RESULT + (nodeList.item(i).getFirstChild().getNodeValue());
}

return RESULT;
}
catch (java.lang.Exception e) {
e.printStackTrace();
}

I am getting an error on the NodeList line "Unable to parse expression; invalid identifier: NodeList.

It maybe I need to declare these but I am not sure of the syntax required

org.w3c.dom.Node;

org.w3c.dom.NodeList;

Understood. Thought that too...

This is the code I used that returns the values for each element that matches a node in the xml.

{

try {

      javax.xml.parsers.DocumentBuilderFactory factory = javax.xml.parsers.DocumentBuilderFactory.newInstance();

      javax.xml.parsers.DocumentBuilder builder = factory.newDocumentBuilder();

      org.w3c.dom.Document domDoc = builder.parse(doc_InputFile);

      javax.xml.xpath.XPath XPath = javax.xml.xpath.XPathFactory.newInstance().newXPath();

      org.w3c.dom.NodeList nodeList = (org.w3c.dom.NodeList) XPath.compile("/CallBack/CB[NUM=0400000000]").evaluate(domDoc, javax.xml.xpath.XPathConstants.NODESET);

                                int i = 0;

                                for (i = 0; i < nodeList.getLength(); i++) {

                                       org.w3c.dom.Node node = nodeList.item(i);

                                       org.w3c.dom.Element eElement = (org.w3c.dom.Element) node;

                                       String Date = eElement.getElementsByTagName("DATE").item(0).getTextContent();

                                       String Time = eElement.getElementsByTagName("TIME").item(0).getTextContent();

                                       String Num = eElement.getElementsByTagName("NUM").item(0).getTextContent();

                                       String Done = eElement.getElementsByTagName("Done").item(0).getTextContent();

                                       RESULT = RESULT +  Date + Time + Num + Done;

                                                                                                     } 

                                return RESULT;

  }

  catch (java.lang.Exception e) {

      e.printStackTrace();

      return null;

  }
