Discard html tags within custom tags while getting text in XHTML using SAX Parser in Groovy

Question

So I am trying to get the text between the tags. So far I have been successful. But sometimes when there are special characters or html tags inside my custom tags I am unable to

Answer 1

I'm not familiar with Groovy so here is a solution in Java. I believe the translation is straighforward.

import java.io.FileInputStream;
import java.io.InputStream;
import java.util.ArrayList;

import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;

import org.xml.sax.Attributes;
import org.xml.sax.helpers.DefaultHandler;

public class SaxHandler extends DefaultHandler {
    ArrayList DefinedTermTitles = new ArrayList<>();
    ArrayList ClauseTitles = new ArrayList<>();
    String currentMessage;
    boolean countryFlag = false;
    StringBuilder message = new StringBuilder();

    public void startElement(String ns, String localName, String qName, Attributes atts) {
        switch (qName) {
            case "ae_clauseTitleBegin":
                countryFlag = true;
                break;

            case "ae_definedTermTitleBegin":
                countryFlag = true; 
                break;           
         }      
    }   

    public void characters(char[] chars, int offset, int length) {
        if (countryFlag) {
            message.append(new String(chars, offset, length));
        }
    }

    public void endElement(String ns, String localName, String qName) {
        switch (qName) {        
            case "ae_clauseTitleEnd":
                ClauseTitles.add(message.toString());
                countryFlag = false;
                message.setLength(0);
                break;

            case "ae_definedTermTitleEnd":
                DefinedTermTitles.add(message.toString());
                countryFlag = false; 
                message.setLength(0);
                break;
         }
    }

    public static void main (String argv []) {
        SAXParserFactory factory = SAXParserFactory.newInstance();
        try {
            String path = "INPUT_PATH_HERE";
            InputStream xmlInput = new FileInputStream(path + "test.xml");
            SAXParser saxParser = factory.newSAXParser();
            SaxHandler handler   = new SaxHandler();
            saxParser.parse(xmlInput, handler);

            System.out.println(handler.DefinedTermTitles);
            System.out.println(handler.ClauseTitles);

        } catch (Exception err) {
            err.printStackTrace ();
        }
    }
}
