Question

I’m trying to read from XML and store the data in a text file.
My code works very well in reading and storing the data, EXCEPT when the paragraph from the XML file contains double quotes.

For example:

    <Agent> "The famous spy" James Bond </Agent>

The output will ignore any data with quotes, and the result would be: James Bond

I’m using SAX, and here is part of my code that might have the issue:

 public void characters(char[] ch, int start, int length) throws SAXException 
  { 
        tempVal = new String(ch, start, length); 
  }

I think I should replace the Quotes before storing the string in my tempVal.

Any ideas???

HERE is the complete code just in case:

public class Entailment {

  private String Text;

  private String Hypothesis;

  private String ID;

  private String Entailment;

}

//Event Handlers
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
    //reset
    tempVal = "";
    if(qName.equalsIgnoreCase("pair")) {
        //create a new instance of Entailment
        tempEntailment = new Entailment();
        tempEntailment.setID(attributes.getValue("id"));
        tempEntailment.setEntailment(attributes.getValue("entailment"));
    }
}

public void characters(char[] ch, int start, int length) throws SAXException {
    tempVal = new String(ch, start, length);
}

public void endElement(String uri, String localName, String qName) throws SAXException {
    if(qName.equalsIgnoreCase("pair")) {
        //add it to the list
        Entailments.add(tempEntailment);
    }else if (qName.equalsIgnoreCase("t")) {
        tempEntailment.setText(tempVal);
    }else if (qName.equalsIgnoreCase("h")) {
        tempEntailment.setHypothesis(tempVal);
    }
}

public static void main(String[] args){
    XMLtoTXT spe = new XMLtoTXT();
    spe.runExample();
}

Answer 1

Your characters() method is being invoked multiple times because the parser is treating the input as several adjacent text nodes. The way your code is written (which you did not show) your are probably keeping only the last text node.

You need to accumulate the contents of adjacent text nodes yourself.

StringBuilder tempVal = null;

public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
    //reset
    tempVal = new StringBuilder();
    ....
}

public void characters(char[] ch, int start, int length) throws SAXException {
    tempVal.append(ch, start, length);
}

public void endElement(String uri, String localName, String qName) throws SAXException {
    String textValue = tempVal.toString();
    ....
    }
}
