Edit: This is an older answer and I would have done it differently today. And I’m not just referring to the dumb snark … since then BeutifulSoup4 is available and it’s really quite nice. I recommend that to anyone who stumbles over here. The currently accepted answer is, well, not what one should do. The … Read more
Here is one example i hope it will be usefull to understand “SAXParser” package test.example; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.net.URL; import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.xml.sax.InputSource; import org.xml.sax.SAXException; import org.xml.sax.XMLReader; import org.xml.sax.helpers.DefaultHandler; import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class XMLParsingDemo extends Activity { private final String MY_DEBUG_TAG = “WeatherForcaster”; … Read more
Assuming you do nothing but parse the document, the ranking of the different parser standards is as follows: 1. StAX is the fastest The event is reported to you 2. SAX is next It does everything StAX does plus the content is realized automatically (element name, namespace, attributes, …) 3. DOM is last It does … Read more
To read from XML in your app, create a folder in your res folder inside your project called “xml” (lower case). Store your xml in this newly created folder. To load the XML from your resources, XmlResourceParser myxml = mContext.getResources().getXml(R.xml.MyXml);//MyXml.xml is name of our xml in newly created xml folder, mContext is the current context … Read more
If you meant, event-based parser then there are a couple of projects out there that do this: http://code.google.com/p/json-simple/ Stoppable SAX-like interface for streaming input of JSON text This project has moved to https://github.com/fangyidong/json-simple http://jackson.codehaus.org/Tutorial Jackson Streaming API is similar to Stax API This project has moved to https://github.com/FasterXML/jackson-core
Stax is the right way. I would recommend looking at Woodstox
As you can see, it’s cutting everything off the url from the ampersand escape code and after. From the documentation of the characters() method: The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into … Read more
SAX parsing is for reading documents, not writing them. You can write XML with the XMLStreamWriter: OutputStream outputStream = new FileOutputStream(new File(“doc.xml”)); XMLStreamWriter out = XMLOutputFactory.newInstance().createXMLStreamWriter( new OutputStreamWriter(outputStream, “utf-8”)); out.writeStartDocument(); out.writeStartElement(“doc”); out.writeStartElement(“title”); out.writeCharacters(“Document Title”); out.writeEndElement(); out.writeEndElement(); out.writeEndDocument(); out.close();

Create a specialization of a SAXException and throw it (you don’t have to create your own specialization but it means you can specifically catch it yourself and treat other SAXExceptions as actual errors). public class MySAXTerminatorException extends SAXException { … } public void startElement (String namespaceUri, String localName, String qualifiedName, Attributes attributes) throws SAXException { … Read more
