Scanning HTML page for HREF AND IMG tags

[Rohan Amin]

Does any body how i could scan an entire html page and look for href and img tags and change some text in the tags.

In a servlet? How would the servlet get the HTML page?

In any case, once you have the HTML source in a string, you'll either need to parse the HTML or (easier) scan the text using regular expressions. As this is not a Servlet issue, it's been moved off the the general forum.

Actual Possible Question #1 - I am developing a web site and I don't know how to use the Find command of my IDE to change some href and image tags.

Actual Possible Question #2 - I am trying to "borrow" work that someone else has already done and make it appear as my own by changing some text in the links and images.

Actual Possible Question #3 - I am trying to scrape porn sites for images. How do I do that?

I crack myself up.

Check out javax.swing.text.html.ParserDelegator. This will find a parser for you, so let it do the dirty work.

Here's some example code:

ParserDelegator parser = new ParserDelegator();
Reader reader = ...
HTMLEditorKit.ParserCallback cb = new HTMLEditorKit.ParserCallback()
{
    public voidhandleStartTag(HTML.Tag t, MutableAttributeSet a, int pos)
    {
        if (HTML.Tag.IMG.equals(t))
        {
            String source = (String)atts.getAttribute(HTML.Attribute.SRC);
        }
    }
 
    public void handleSimpleTag(HTML.Tag t, MutableAttributeSet a, int pos)
    {
        handleStartTag(t, a, pos);
    }
};
parser.parse(reader, cb, true);
