使用Java从XML检索文本和标签

Question

I have an xml file as follows:

<extended>
   <p>text A</p>
   <p>text B</p>
   <p>text C</p>
</extended>

Using Java I would like to extract the text and the tags from the extended node. So my expected output would be:

<p>text A</p>
<p>text B</p>
<p>text C</p>

Here's my code so far:

String textString;
NodeList extendedNodeList = XYZ.getElementsByTagName("extended");
if(extendedNodeList !=null && extendedNodeList.getLength() == 1) {
    Node subChildNode = extendedNodeList.item(0);
    if(subChildNode.getNodeType() == Node.ELEMENT_NODE)
        textString = subChildNode.getTextContent();
}

However, this strips the tags, leaving me with:

text A
text B
text C

How to leave in the <p> tags? Any help would be greatly appreciated :).

This will solve your problem

NodeList extendedNodeList = XYZ.getElementsByTagName("extended");
if(extendedNodeList !=null && extendedNodeList.getLength() == 1) {
    Node extendedNode = extendedNodeList.item(0);
    if (extendedNode.hasChildNodes()) {
        NodeList childNodes = extendedNode.getChildNodes();
        for (int i = 0; i < childNodes.getLength(); i++) {
            Node pNode = childNodes.item(i);
            if(pNode.getNodeType() == Node.ELEMENT_NODE) {
                Element element = (Element)pNode;
                System.out.println("<" + element.getTagName() + ">" + element.getTextContent() + "</" + element.getTagName() + ">");
            }
        }
    }
}
