Hello,
I want to get information via HTTPS on the next site
https://b840b937347535c0bb8a81e134cf294349aa2852:[email protected]/people.xml
but i can't get the xml data. I'm new onto HTTPS connections, but i
have a snippet of code about it, and when i run the Application i get
the next error: Error Null
Here's the Code from my class ParsingXML.java
package com.purplecat.hr;
import java.io.InputStream;
import java.net.URL;
import javax.net.ssl.HttpsURLConnection;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class ParsingXML extends Activity {
private static final String MY_DEBUG_TAG = "WeatherForcaster";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
/* Create a new TextView to display the parsingresult later.
*/
TextView tv = new TextView(this);
try{
/* Create a URL we want to load some xml-data from. */
URL url = new URL("https://
b840b937347535c0bb8a81e134cf294349aa2852:[email protected]/
people.xml");
HttpsURLConnection httpsConnection = null;
httpsConnection.setHostnameVerifier(new
AllowAllHostnameVerifier());
httpsConnection = (HttpsURLConnection) url.openConnection();
httpsConnection.connect();
InputStream inputStream = httpsConnection.getInputStream
();
/* Get a SAXParser from the SAXPArserFactory. */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
/* Get the XMLReader of the SAXParser we created. */
XMLReader xr = sp.getXMLReader();
/* Create a new ContentHandler and apply it to the XML-
Reader*/
ExampleHandler myExampleHandler = new ExampleHandler();
xr.setContentHandler(myExampleHandler);
/* Parse the xml-data from our URL. */
xr.parse(new InputSource(inputStream));
/* Parsing has finished. */
/* Our ExampleHandler now provides the parsed data to us.
*/
ParsedExampleDataSet parsedExampleDataSet
=myExampleHandler.getParsedData();
/* Set the result to be displayed in our GUI. */
tv.setText(parsedExampleDataSet.toString());
} catch (Exception e){
/* Display any Error to the GUI. */
tv.setText("Error "+e.getMessage());
Log.e(MY_DEBUG_TAG, "WeatherQueryError", e); }
/* Display the TextView. */
this.setContentView(tv);
}
}
>From ExampleHandler.java

/** Gets be called on opening tags like:

}else if (localName.equals("tagwithnumber")) {

myParsedExampleDataSet.setExtractedInt(i);
}
}
/** Gets be called on closing tags like:

}
}
/** Gets be called on the following structure:

@Override
public void characters(char ch[], int start, int length) {
if(this.in_mytag){
myParsedExampleDataSet.setExtractedString(new String(ch,
start, length));
}
}
}
And from ParsedExampleDataSet.java
package com.purplecat.hr;
public class ParsedExampleDataSet {
private String extractedString = null;
private int extractedInt = 0;
public String getExtractedString() {
return extractedString;
}
public void setExtractedString(String extractedString) {
this.extractedString = extractedString;
}
public int getExtractedInt() {
return extractedInt;
}
public void setExtractedInt(int extractedInt) {
this.extractedInt = extractedInt;
}
public String toString(){
return "ExtractedString = " + this.extractedString
+ "\nExtractedInt = " + this.extractedInt;
}
}
