compare text contents of xml element and add child element to a particular node in Java

i have an arraylist which contains title and fullname in the following format

Dr.|ricardo bettati
Prof. Dr.-Ing.|Helmut sperling
miss|angela link

First i am splitting the contents with |.I will get the title and fullnames. Then i split fullnames with space to get firstname and familyname.

Now i have 3 strings

String title\which contains title from above list String firstname; String familynames;

The next task is i have check the text contents of existed xml with the above strings firstname and familyname.Here is the existed xml

<person>
 <name>
   <firstname>Jean-Luc</firstname>
   <familyname>DeLorme</familyname>
 </name>
</person>
<person>
 <name>
   <firstname>Dave</firstname>
   <familyname>Sperling</familyname>
 </name>
</person>
<person>
 <name>
    <firstname>Helmut</firstname>
    <familyname>sperling</familyname>
 </name>
</person>

If the firstname and familyname contets matches with the text content of above xml elements <firstname>,<familyname> then i have to create an element named <title> and append the corresponding title from my list.My XML supposed to look like the following

<person>
 <name>
   <firstname>Jean-Luc</firstname>
   <familyname>DeLorme</familyname>
 </name>
</person>
<person>
 <name>
   <firstname>Dave</firstname>
   <familyname>Sperling</familyname>
 </name>
</person>
<person>
 <name>
    **<title>Prof. Dr.-Ing.>/title>**
    <firstname>Helmut</firstname>
    <familyname>sperling</familyname>
 </name>
</person>

I have tried with the following code

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        dbf.setValidating(false);
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document doc = db.parse(new FileInputStream(new File("Final-Results.xml")));
        Element element =  doc.getDocumentElement();
        NodeList list = doc.getElementsByTagName("person");
        for (int i=0;i<titles.size();i++) { //Title is my arraylist
            String names = (String) titles.get(i);
            String[] content=names.split("\\|");
            String title=content[0];
            String[] fullname=content[1].split("\\s+");
            String firstname=fullname[0];
            String familyname=fullname[1];
            for (int n = 0; n < list.getLength(); n++) {

                   Node node = list.item(n);
                   if ("firstname".equals(node.getNodeName()) && node.getTextContent().equals(firstname)) {
                    System.out.println("haii");
                   }
            }
        }

But how do i get the children and check the text contents and create node at particular place?

Child node appending:
    Element childElement = doc.createElement("title");
    // set attributes, etc
    node.appendChild(childElement);

Code can be simplified with xPath, like:

    String xPathExpression = "*/person/name[firstname/text() = 'Helmut' and familyname/text() = 'sperling']";
    XPath path = XPathFactory.newInstance().newXPath();
    NodeList nl = (NodeList) path.evaluate(xPathExpression, doc, XPathConstants.NODESET);
    for (int i = 0; i < nl.getLength(); i++) {
        Element childElement = doc.createElement("title");
        childElement.appendChild(doc.createTextNode("Dr."));
        nl.item(i).insertBefore(childElement,((Element)nl.item(i)).getFirstChild());
    }

If run code on specified example, result is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><result>
<person>
 <name>
   <firstname>Jean-Luc</firstname>
   <familyname>DeLorme</familyname>
 </name>
</person>
<person>
 <name>
   <firstname>Dave</firstname>
   <familyname>Sperling</familyname>
 </name>
</person>
<person>
 <name><title>Dr.</title>
    <firstname>Helmut</firstname>
    <familyname>sperling</familyname>
 </name>
</person>
</result>
