Parsing http XML response in JAVA (BlackBerry)

Being foolish/novice enough, I had got stuck in how to parse an XML one receives in form of http response.

I could find many ways where one can parse an XML file – but reading http XML response became a challenge for me. Writing the response to a file and then reading the XML from there was not the ideal way. Being round the bend for quite a while, I was able to get things work.

Here is the code snippet, if anyone wants to refer:

——–

// send http request for XML response via connection object

// input stream http response

InputStream inpStream = connection.openInputStream();

parseStringXML(inpStream);
 

// Parsing XML using SAX

void parseStringXML(InputStream xmlString){

try {

SAXParserFactory spf = SAXParserFactory.newInstance();

spf.setNamespaceAware(true);

SAXParser sp = spf.newSAXParser();

Status.show("preparing parse");

sp.parse(xmlString, new Handler());

}

catch (Throwable t) {

Status.show("exception in ParseStringXML");

t.printStackTrace();

}}

// Parse SAX Handler – for getting a particular attribute of a tag

class Handler extends DefaultHandler {

boolean tag = false;

boolean attribute   = false;

public void startElement(String nsURI, String strippedName,

String tagName, Attributes attributes)

{

if (tagName.equalsIgnoreCase("tagName")){

title = true;

bookMarksReceivedField = new LabelField(attributes.getValue("attribute"), FOCUSABLE );

}}}
