BIG PROBLEM
Hello,
I am Stefan a Grad student at UNC. I am working on research using Globus
and other grid services platforms. I am kinda stuck with getting the data
from MessageElement array. I have seen this mail:
http://www.mail-archive.com/axis-dev@xml.apache.org/msg09363.html
I have the same problems as the researcher. I see that she has attached a
MessageElementHelper class and that is deleted. I have attached a slice of
code below. Maybe you can give me some ideas how to parse the MessageElement:
MessageElement[] elements = res.get_any();
for( int i = 0; i < elements.length; i++ )
{
System.out.println("Query result:");
// an iterator over all attribute names
java.util.Iterator printIter = elements[i].getAllAttributes();
int k = 0;
while( printIter.hasNext( ) )
{
Name n = ( Name )printIter.next( );
k++;
}
Attributes att = elements[i].getAttributes( );
System.out.println( "len = " + att.getLength( ) );
System.out.println( "k = " + k );
}
Both of the len and k are 1. I have to expand the attribute.
The service data file is:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="BasicSensorData"
targetNamespace="http://www.renci.org/namespaces/2004/Autopilot/BasicSensorService_sd/BasicSensorSDE"
xmlns:tns="http://www.renci.org/namespaces/2004/Autopilot/BasicSensorService_sd/BasicSensorSDE"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<wsdl:types>
<schema
targetNamespace="http://www.renci.org/namespaces/2004/Autopilot/BasicSensorService_sd/BasicSensorSDE"
attributeFormDefault="qualified"
elementFormDefault="qualified"
xmlns="http://www.w3.org/2001/XMLSchema">
<complexType name="BasicSensorDataType">
<sequence>
<element name="data" type="int"/>
<element name="programName" type="string"/>
<element name="managerHost" type="string"/>
<element name="value" type="string"/>
<element name="dataType" type="string"/>
<element name="sensorName" type="string"/>
</sequence>
</complexType>
</schema>
</wsdl:types>
</wsdl:definitions>
As you may expect I need the values for all elements (data, programName,
managerHost, value, dataType, sensorName).
Any ideas will be of great help. Thank you.

Posted by zo...@email.unc.edu.
First of all thank you. The problem is that I do not have a file. I have only
the MessageElement array. I do not read any file, or build any document. From
that I can get the iterator, but it iterates through one attribute. I need to
expand that one. The essential part in youw code that I cannot use is:
Element rootElement = document.getRootElement();
Iterator elementList = rootElement.getDescendants(new
ElementFilter("element"));
Maybe you can detaliate more this solution.

I would use JDOM ( http://www.jdom.org ) in the following manner:
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.util.Iterator;
import java.util.List;
import org.jdom.Attribute;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.JDOMException;
import org.jdom.filter.ElementFilter;
import org.jdom.input.SAXBuilder;
/*
* Created on Jan 5, 2005
*/
/**
* @author Hugo A. Garcia
*/
public class ParserSpike {
private File inputFile;
/**
* @param outputFile
* @param inputFile
*
*/
public ParserSpike(File inputFile) {
super();
this.inputFile = inputFile;
if (!inputFile.exists()) {
System.out.println("The input file" + inputFile.getPath()
+ "does not exist");
System.exit(1);
}
}
public static void main(String[] args) {
File inputFile = new File(args[0]);
new ParserSpike(inputFile).run();
}
/**
*
*/
private void run() {
Document document = null;
URL fileURL;
SAXBuilder builder = new SAXBuilder();
try {
fileURL = inputFile.toURL();
document = builder.build(fileURL);
Element rootElement = document.getRootElement();
Iterator elementList = rootElement.getDescendants(new
ElementFilter("element"));
while (elementList.hasNext()) {
Element nextElement = (Element) elementList.next();
List attributeList = nextElement.getAttributes();
Iterator attributeIterator = attributeList.iterator();
while (attributeIterator.hasNext()) {
Attribute attribute = (Attribute) attributeIterator.next();
System.out.print(attribute.getName() + " = " +attribute.getValue() + " ");
}
System.out.println();
}
} catch (IOException e) {
e.printStackTrace();
} catch (JDOMException e) {
e.printStackTrace();
}
}
}
The Output is the following:
name = data type = int
name = programName type = string
name = managerHost type = string
name = value type = string
name = dataType type = string
name = sensorName type = string
