Can anyone show me how I would parse this?
I am not exactly sure how I would go about doing this. Here is the
parsing code I have.
public class TwitterResponse {
private static final String TOP_LEVEL_NODE_NAME = "status"; // the
top level <status> node to be read
private static final String USER_NODE_NAME = "user"; // the
<user>
node which has sub-nodes
private static final String TEXT_NODE_NAME = "#text"; // basic
textual element
DocumentBuilder builder;
NodeList nodes;
HashMap<Integer,TwitterEntry> entries = new
HashMap<Integer,TwitterEntry>();
/**
* Create JAXP based parser and read XML from an InputStream.
*
* @param xmlStream InputStream with XML data
*
* @throws SAXException
* @throws IOException
* @throws ParserConfigurationException
*/
public TwitterResponse()
throws SAXException, IOException, ParserConfigurationException {
builder =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
}
public TwitterResponse parse(InputStream xmlStream)
throws SAXException, IOException, ParseException,
MalformedURLException {
Document d = builder.parse(xmlStream);
nodes = d.getElementsByTagName(TOP_LEVEL_NODE_NAME);
readEntries();
return this;
}
public TwitterResponse parse(String xmlString)
throws SAXException, IOException, ParseException,
MalformedURLException {
Document d = builder.parse(new InputSource(new StringReader
(xmlString)));
nodes = d.getElementsByTagName(TOP_LEVEL_NODE_NAME);
readEntries();
return this;
}
/**
* Number of items read by this parser
*
* @return Get the total number of <status> nodes returned
*/
public int getNumberOfItems() {
return entries.size();
}
/**
* Get the index'th <status> node by walking the DOM
*
* @param index the index of the node you want to get
* @return TwitterEntry representation of that node
* @throws ParseException
*/
public TwitterEntry getItemAt(int index) {
return entries.get(index);
}
//
private void readEntries()
throws ParseException, MalformedURLException {
for (int i = 0; i < nodes.getLength(); i++) {
entries.put(i, readEntry(i));
}
}
// [FIXME] Need to rewrite the parsing code, does not support #8220;
like codes
private TwitterEntry readEntry(int index)
throws ParseException, MalformedURLException {
TwitterEntry entry = new TwitterEntry();
// nd is the list of child nodes of the <status> element with
the
specified index
NodeList nd = nodes.item(index).getChildNodes();
// loop through all the children
for(int i = 0; i < nd.getLength(); i++)
{
// for some reason JAXP treats white space as #text
nodes, so let's
skip them
if(!nd.item(i).getNodeName().equals(TEXT_NODE_NAME))
{
// the <user> element has subnodes so we need
additional
processing
if(nd.item(i).getNodeName().equals(USER_NODE_NAME))
{
// nd_usr will contain all the child
nodes of <user>
NodeList nd_usr =
nd.item(i).getChildNodes();
for(int j=0; j<nd_usr.getLength(); j++)
{
// once again we are skipping
blank lines and whitespace
if(!nd_usr.item(j).getNodeName().equals(TEXT_NODE_NAME))
{
// [TODO] figure out
how to prevent User ID from overwriting
post ID
String value ="", name
= nd_usr.item(j).getNodeName(); // get
the name of the current node
if(nd_usr.item(j).hasChildNodes())
// if not empty, also
get the value
value =
nd_usr.item(j).getFirstChild().getNodeValue();
entry.addAttribute(name, value);
}
}
}
else
{
String value ="", name =
nd.item(i).getNodeName();
if(nd.item(i).hasChildNodes())
value =
nd.item(i).getFirstChild().getNodeValue();
entry.addAttribute(name, value);
}
}
}
return entry;
}
}
