    Default Pulling data from a URL

    I am hoping to write a program that will take in a URL as input and then search through the text on that webpage to pull out relevant data.
    Essentially, my plan was to have the program search the webpage on certain strings and then find and record the numbers on the same line to compile into another file. Luckily, all of the data I need are in tables on the webpage so I assumed that would make it easier to get the data.

    The problem that I am facing is that I do not know where to start. I have been searching the web for answers to this but, unfortunately, the only thing people tend to recommend is using an HTML parser. This would not help since HTML code is not what I am looking for and does not include the data I seek. Having said that, simply pointing me in the right direction on this issue would be substantially helpful.

    In advance, I appreciate your help.

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    Data mining of web pages is a huge topic that can't be distilled into a few pages or links. I haven't seen this topic discussed here, so I don't know what experience might be available to help you. Since you're somewhat vague about what you're looking for, I suggest you continue to read what you can on data mining and return when you can be less vague about what help you need.

    Have you looked at the text of the web page that is returned by the server? View Source in most browsers.
    If the protocol is HTTP then the page should be wrapped in html and can contain some javascript to make it very confusing and hard to parse.
    If you don't understand my answer, don't ignore it, ask a question.
