XML Parsing Problem.

[Hardik Trivedi]

Hi all,

I am fetching a data from an XML. XML has few data and images encoded in base 64. Now problem is base 64 is having very large text.And somehow it is fetching a few part of data.
e.g. if data is of length of 3000 lines it reads 1000 or 2000 lines only.

I can not figure out the problem.Because it is not in my control. Parsers are provided by Java only.
I am using SAX parcer.

Following is small amount of code which I have written.

public void startElement(String uri, String localName, String qName,Attributes attributes) throws SAXException 
    {
        currentElement = true;
 
        if (localName.equals("Category"))
        {
            /*ci = new ChannelInfo();
            ci.setcategoryId(Integer.parseInt(attributes.getValue("ID")));
            ci.setcategoryName(attributes.getValue("Name"));
            */
        	categoryId = Integer.parseInt(attributes.getValue("ID"));
        	categoryName = attributes.getValue("Name");
        } 
        else if (localName.equals("Channel")) 
        {
            /** Get attribute value */
    		ci = new ChannelInfo();
    		ci.setchannelId(Integer.parseInt(attributes.getValue("ID")));
            ci.setchannelName(attributes.getValue("Name"));
            ci.setcategoryId(categoryId);
            ci.setcategoryName(categoryName);
        }
    }
	
	public void endElement(String uri, String localName, String qName)throws SAXException 
	{
		if(localName.equalsIgnoreCase("ChannelLogo"))
		{
			ci.setImage(currentValue);
		}
		else if(localName.equalsIgnoreCase("Channel"))
		{
			ciList.addChannelInfo(ci);
		}
	}
	
	public void characters(char[] ch, int start, int length)throws SAXException 
	{
		if (currentElement) 
		{
			currentValue = new String(ch, start,length);
			currentElement = false;
		}
	}

Now that characters method is not getting whole data in array.

Please help me out.

The characters method is not guaranteed to receive all of a text string in one go. It may be called multiple times for a single piece of text - which is what is happening here. Instead of trying to process the text in the characters method, you should just buffer it (in a StringBuilder maybe) and then process the contents of the buffer the next time the endElement method is called.

What does this have to do with Android?

Changed the parser and solve the problem. Thanks all.
