如何将XML内容作为String获取

Question

<root>
<h id="1">
    <d value="1,2,3,4,5"><open>10:00</open><close>23:00</close></d>
    <d value="6"><open>10:00</open><close>2:00</close></d>
    <d value="7"><open>10:00</open><close>21:00</close></d>
</h>
<h id="2">
</h>
</root>

Here I have the XML which root has list of <h> tagged nodes. Now I need to break these into parts and set it into different variables (add into a map).

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(new InputSource(new ByteArrayInputStream(data.getBytes("utf-8"))));
NodeList nList = doc.getElementsByTagName("h");
for (int i = 0; i < nList.getLength(); i++)
{
    Node nNode = nList.item(i);
    System.out.println(nNode.getAttributes().getNamedItem("id") + " " + ?????);        
}

what should I call in order to get the value ( String value ) of a nNode ?

Here is what Im looking for as the asnwer for the above code once some one fills the ????

1 <h id="1"><d value="1,2,3,4,5"><open>10:00</open><close>23:00</close></d><d value="6">open>10:00</open><close>2:00</close></d><d value="7"><open>10:00</open><close>21:00</close></d></h>
2 <h id="2"></h>

And i don't mind having as root element

Answer 1

You can use Node.getTextContent() to conveniently get all the text of a node (gets text of children as well).

See Parsing xml file contents without knowing xml file structure for a short example.

If you're trying to get the value attributes of the d nodes (I can't actually tell, your question is slightly unclear to me), then it would be different -- for that you would iterate through the children of each h node (use getChildNodes() or getFirstChild() + getNextSibling() ) then grab their value attributes just as you are getting the id attribute of the h nodes (the above link also shows an example of iterating through child nodes).

Answer 2

Have you tried jDom library? http://www.jdom.org/docs/apidocs/org/jdom2/output/XMLOutputter.html

 XMLOutputter outp = new XMLOutputter();
 String s = outp.outputString(your_jdom_element);

Answer 3

如果您使用的是来自javax.xml.soap.Node Node，您是否尝试过nNode.toString() 。

Answer 4

You can use that:

http://docs.oracle.com/javase/7/docs/api/org/w3c/dom/Node.html#getTextContent()

but your sample nNode has other nodes, not just text. It seems you need helper method to construct String from child nodes.

Pass your nNode to nodeToString
