=========================

plz see below code.

public static void main(String args[]) throws Exception { InputStream is = Nullsoft.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); HTMLEditorKit htmlKit = new HTMLEditorKit(); HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument(); HTMLEditorKit.Parser parser = new ParserDelegator(); HTMLEditorKit.ParserCallback callback = htmlDoc.getReader(0); parser.parse(br, callback, true); // Parse ElementIterator iterator = new ElementIterator(htmlDoc); Element element; while ((element = iterator.next()) != null) { AttributeSet attributes = element.getAttributes(); Object name = attributes.getAttribute(StyleConstants.NameAttribute); if ((name instanceof HTML.Tag) && ((name == HTML.Tag.DIV) || (name == HTML.Tag.H2) || (name == HTML.Tag.H3))) { StringBuffer text = new StringBuffer(); int count = element.getElementCount(); for (int i = 0; i < count; i++) { Element child = element.getElement(i); AttributeSet childAttributes = child.getAttributes(); // if (childAttributes.getAttribute(StyleConstants.NameAttribute) == HTML.Tag.CONTENT) { int startOffset = child.getStartOffset(); int endOffset = child.getEndOffset(); int length = endOffset - startOffset; text.append(htmlDoc.getText(startOffset, length)); } } System.out.println(name + ": " + text.toString()); } } System.exit(0); } public static InputStream getInputStream() { String text = "<html>\n" + "<head>\n" + "<title>pg_0001</title>\n" + "\n" + "<style type=\"text/css\">\n" + ".ft3{font-style:normal;font-weight:bold;font-size:11px;font-family:Helvetica;color:#000000;}\n" + "</style>\n" + "</head>\n" + "<body vlink=\"#FFFFFF\" link=\"#FFFFFF\" bgcolor=\"#ffffff\">\n" + "\n" + "\n" + "<div style=\"position:absolute;top:597;left:252\"><nobr><span class=\"ft3\">Christina Toth, Pharm.

Try this instead.

Edited to use the read() HTMLEditorKit .

 import java.io.StringReader; import javax.swing.text.AttributeSet; import javax.swing.text.Element; import javax.swing.text.ElementIterator; import javax.swing.text.StyleConstants; import javax.swing.text.html.HTML; import javax.swing.text.html.HTMLDocument; import javax.swing.text.html.HTMLEditorKit; public class NewMain { public static void main(String args[]) throws Exception { HTMLEditorKit htmlKit = new HTMLEditorKit(); HTMLDocument htmlDoc = (HTMLDocument) htmlKit.createDefaultDocument(); htmlKit.read(new StringReader(text), htmlDoc, 0); // Parse ElementIterator iterator = new ElementIterator(htmlDoc); Element element; while ((element = iterator.next()) != null) { AttributeSet as = element.getAttributes(); Object name = as.getAttribute(StyleConstants.NameAttribute); if (name == HTML.Tag.DIV) { StringBuffer sb = new StringBuffer(); sb.append(name).append(": "); int count = element.getElementCount(); for (int i = 0; i < count; i++) { Element child = element.getElement(i); int startOffset = child.getStartOffset(); int endOffset = child.getEndOffset(); int length = endOffset - startOffset; sb.append(htmlDoc.getText(startOffset, length)); } System.out.println(sb); } } } private static String text = "<html>\n" + "<head>\n" + "<title>pg_0001</title>\n" + "\n" + "<style type=\"text/css\">\n" + ".ft3{font-style:normal;font-weight:bold;font-size:11px;" + "font-family:Helvetica;color:#000000;}\n" + "</style>\n" + "</head>\n" + "<body vlink=\"#FFFFFF\" link=\"#FFFFFF\" bgcolor=\"#ffffff\">\n" + "\n" + "\n" + "<div style=\"position:absolute;top:597;left:252\"><nobr><span " + "class=\"ft3\">Christina Toth, Pharm. D.</span></nobr></div>\n" + "\n" + "\n" + "</body>\n" + "</html>"; }

Console:
