Is BufferedReader able to handle 100,000 lines of HTML source code?

public void fetch_device_data(String device_name){
 
        String s = null;
		String data = null;
 
        try {
            
            Process p = Runtime.getRuntime().exec("wget -O - http://user:pass@61.10.0.168/cgi-bin/chkdocoper_chid.cgi?"+device_name);
            
            BufferedReader stdInput = new BufferedReader(new 
                 InputStreamReader(p.getInputStream()));
			
            while ((s = stdInput.readLine()) != null) {
				data += s;
            }
        }
        catch (IOException e) {
            write_log("exception happened - here's what I know: ");
            e.printStackTrace();
            System.exit(-1);
        }
		
		if(data != null){
			int first_pos = data.indexOf("<table");
			int last_pos = data.lastIndexOf("</table>");
			
			if(first_pos != -1 && last_pos != -1){
				data = data.substring(first_pos, last_pos + 8);
				data = data.replaceAll("<[/]{0,1}table[^>]*>", "");		//Remove all table tags
				data = data.replaceAll("<(tr|td)[^>]*>", "<$1>");		//Remove all the attributes in tr and td tags
				data = data.replaceAll("<([/]{0,1}[a-z]*)>[ ]*", "<$1>").trim();
				data = data.replaceAll("</(td|tr)>", "");				//Remove all ending tr and td tags
				data = data.replaceFirst("<tr>", "");				//Remove the first tr tag, which is not required, during split
				
				String temp[] = data.split("<tr>");
				result = new String[temp.length][];
				for(int i=0; i<temp.length; i++){
					temp[i] = temp[i].replaceFirst("<td>", "");
					result[i] = temp[i].split("<td>");
				}
			}
		}
    }
