HI,<br> I have written the following program called process.java to parse a file called login.html which is also given below. But I am not able to get the data which is in SCRIPT tag. Check out the output I got for the process.java. One more thing I getting "?" in place of when I copy the output and run it.<br> Please find out the errors and give me the solution for two problems. <br><br> process.java<br> ------------<br> &l t;br> import java.util.*;<br> import java.io.*;<br> import javax.swing.text.*;<br> import javax.swing.text.html.*;<br> import javax.swing.text.html.parser.*;<br> import java.net.*;<br> import ParserGetter.*;<br> class parse1 extends HTMLEditorKit.ParserCallback {<br> StringBuffer sb=new StringBuffer();<br> public void handleText(char[] text,int position)<br> {<br> sb.append(text);<br> System.out.println(text);<br> }<br> public void handleEndTag(HTML.Tag tag,int position)<br> {<br> sb.append("<").append("/").append(tag).append(">");<br> System.out.println("<"+"/"+tag+">");<br> }<br> public void handleSimpleTag(HTML.Tag <br>tag,MutableAttributeSet attributes,int position) {<br> int ind=0;<br> String store1="";<br> String tok[]=new String[50];<br> sb.append("<").append(tag);<br> System.out.print("<"+tag);<br> Enumeration e=attributes.getAttributeNames();<br> while(e.hasMoreElements())<br> {<br> Object name=e.nextElement();<br> Object value=attributes.getAttribute(name);<br> sb.append(" ").append(name).append("=").append(value);<br> System.out.print(" "+name+"="+value);<br> }<br> sb.append(">");<br> System.out.print(">");<br> System.out.println();<br> }<br> public void handleStartTag(HTML.Tag tag,MutableAttributeSet attributes,int position) {<br> sb.append("<").append(tag);<br> System.out.print("<"+tag);<br> Enumeration e=attributes.getAttributeNames();<br> while(e.hasMoreElements())<br> {<br> Object name=e.nextElement();<br> Object value=attributes.getAttribute(name);<br> sb.append(" ").append(name).append("=").append(value);<br> }<br> sb.append(">"); System.out.print(">"); }<br>
