Parsing xml attributes crash

Hi

Im quite n00bis about java programming. Looking through a lot of tutorials on how to pars xml.

Here is a cut of the xml I want to parse

Code:

---

<Component>
  <Type Name="1">
    <Item ItemNo="1"                Name="First" Value="1" Config="1"></Item>
  </Type>

  <Type Name="2">
    <Item ItemNo="2"                Name="1" Value="3"  Config="2"></Item>
    <Item ItemNo="3"            Name="3" Value="" Config="3"></Item>
  </Type>
</Component>

---

I have found a great tutorial here: simple sax xml parser

But when the xml comes to the last "node end" ( </Component>) I get this error:

Code:

and my application closes.

Can anyone help me??

What you have on Main.java:46? Can you show us the code?

I deleted you other identical thread; both threads were moderated and I approved this one so it's visible to everyone now.

kind regards,

According to the stack trace I don't think the error has something to do with parsing the XML text; a SWT widfget complains; I think it's an error in your gui.

kind regards,

Well the thing is that I tried to put a string array (that was empty) into a table.

The next thing for me is to figure out how to turn the console output into a string, pref a string array.

From the tutorial I have this code bit:

Code:

---

private static final class SaxHandler extends DefaultHandler {
                // invoked when document-parsing is started:
                 
                  StringBuffer accumulator = new StringBuffer(); // Accumulate parsed text

                public void startDocument() throws SAXException {
                    System.out.println("Document processing started");
                }
               
                // notifies about finish of parsing:
                public void endDocument() throws SAXException {
                    System.out.println("Document processing finished");
                }
        public void startElement(String uri, String localName,
                String qName, Attributes attrs) throws SAXException {
                accumulator.setLength(0);
            if (qName.equals("Component")) {
            } else if (qName.equals("Type")) {
                   
                    String TypeName = attrs.getValue("Name");
                    System.out.println("Type "+ TypeName);
                   
            } else if (qName.equals("Item")) {
                   
//                    ItemNo value as String:
              String ItemNo = attrs.getValue("ItemNo");
              // name as a String:
              String Name = attrs.getValue("Name");
              // value as a String:
              String Value = attrs.getValue("Value");
              // config value as a String:
              String Config = attrs.getValue("Config");
           
              String XMLtable = ItemNo + Name + Value + Config;
              System.out.println("Item " + ItemNo +" " + Name +" " + Value +" "+ Config);
             
             
                        }  else {
                               
                throw new IllegalArgumentException("Element '" +
                        qName + "' is not allowed here");
                        }
           
           
        }
       
        // we leave element 'qName' without any actions:
        public void endElement(String uri, String localName, String qName)
        throws SAXException {
            // do nothing;
        }
     
      }

I cannot get access to the XMLtable string array.

EDIT:
I would also like to have all TypeName strings in a array (or similar) so i can have them i a Combo

Any ide?

Thanks for answering so fast anyways

What is the actual exception.
I can only see the stack trace.

I forgot to add it in I'm sorry here it is..

Code:

---


java.lang.IllegalArgumentException: Argument cannot be null

---

these lines caused the exception:

Code:

---

TableItem item1 = new TableItem(table, SWT.NONE);
            item1.setText(XMLItem);

---

the String array XMLItem is empty..

But as I asked. Is there a way of getting the

Code:

---

system.out.println

---

converted to a string or string array?

You are using qualified names instead of local names, so I take it that you do not have any default namespace declarations in your XML document?

EDIT: Actually, qname and localname should be the same in your case...

You haven't shown us the declaration for XMLItem so how can we help?

The XMLItem is decleared in the top of the "main" class this way

Code:

---

Public String [] XMLItem;

---

The thing is that I want the strings created in the parsed section to become a string array that i can put in my Table as in the picture.
I get all the stuff from the XML into the console view of eclipse. But cant quite figure out how to put it into a string array so that I can put it in the table.

I dont have the code in front of me right now but I know this is how ;)

I dont use it anywhere else than right here..


Maybe this should go into another thread??
