Parsing HTML

Hi

I have html files on my sites, which contain download links in a specfic way. e.g

FS2004 Aircraft 
Download: <a href="http://www.@@@@.com/cgi-bin/download.pl?url=uploads04/apr/247hal.zip" target="main2">
247hal.zip</a> (1936 KB)<img
src="images2/uploads04/apr/247hal.jpg"
align="right" hspace="0" width="189" height="73">
Author:

Date: 2004-04-19 
FS2004 Boeing
247D, Heather Aviation Ltd. 
These are textures ***ONLY*** and are applied to any of Dee Waldron's
models, this one in particular being the WhiteYellow Boeing 247,
filename: boeing247yellowwhite.zip (which contains the entire model).
This is an FS2002 model but this texture package also contains an
updated aircraft.cfg file making it compatible for FS2004.
<hr color="#87A9DC">

This pattern is repeated for the rest of the downloads on the page. How would use java to get the urllink, the picture and the the rest of the details on the page. Example

Outputs using system.out.prinln :
FS2004 Aircraft
247hal.zip

This is being done, so I can change the ouput into a insertsql query.

Thanks in advance of any help

Use HTMLEditorKit.

Hi

Thanks for the link, though I don't want to get the links, but just the data. As the output contains no links.

u can use similiar techniques to extract whatever data you require.

Can you explain how I can change that code, to get the authors name by its self?

Also, the code does'nt not run, it does'nt seem to recognise HTMLDocument doc = new HTMLDocument() . even when you import import javax.swing.*;

import javax.swing.text.html.*;

The java code still does'nt compile. I have added the following imports:
import javax.swing.text.html.*;
import java.io.*;
import java.net.*;
import javax.swing.text.EditorKit;

and it has trouble on } catch (BadLocationException e) {.

I just want to get specfic data back from the html, not all of it.

Thanks

Akbar

what are the errors exactly?
you need to add that method to your class.

The error from bluej says " cannot resolve symbol" on that line.

If I got the html file, and placed the file data into a txt file, then opened it up and it was all a string, would I be able to split the file up taking the part "....<hr color="#87A9DC">" ?

Thanks again

import javax.swing.text.*;

Well it comiples, though whatever url I try it returns with a empty String.

I am totally lost on which way to go about it. There must be way to search a string and return certain parts of it???

Akbar

you can parse the string manually if you like but its a lot simpler to use an existing parser isn't it?

Thanks for your help guys, though both way seem to complicated for me, I have put up another post using the string method. I will close this question soon, just in case I get further replies.
