    Hi,

    the question is unclear. What exactly do you mean by "contents"? Do you want only a specific (list of) web pages? Do you want to extract information from the Web page?
    Please specify?

    Cheers,
    Simon

    Hi Simon,
    I want to extract information from web page.If I can copy the contents in the web page as a text file,then I will apply text mining algorithms.So now I need to copy the web page in to a text file.

    Thanks
    Ratheesan.

    Hi,
    I guess you might change the "max_depth" parameter to zero. The crawler shouldn't then follow any links.

    With RapidMiner 5 there will soon be a web mining extension making this more easily.

    Hai,

    I have tried with the above method and I saved it as a text file. The saved text contains html tags and image url's etc... Is there any way to save only the texts (the text that is seen by a user when he opens a web page).

    Thanks,
    Ratheesan

    Hi,
    with 5.0 this would be easy, in 4.x you can only set the TextInput to contenttype html, so that all tags are filtered out.
