AJAX calls situation is a bit more complex, but let's not bother with that in this post.. When you know the pattern for page number parameter, all it's needed is a simple loop with something like: string url = string. Format(. How to extract data from a webpage? You can use. Web. Request/Web. Response or Web. Client classes from System. Net namespace to get page content. After that you can obtain information via regular expressions. You can also try to treat downloaded content as XML and scrutinize it with XPath or LINQ to XML. These are not good approaches, however. For complicated page structure writing correct expression might be difficult, one should also remember that in most cases webpages are not valid XML documents. Fortunately, HTML Agility Pack library was created. It allows convenient parsing of HTML pages, even these with malformed code (i. HAP goes through page content and builds document object model that can be later processed with LINQ to Objects or XPath. To start working with HAP you should install Nu. Get package named Html. Agility. Pack (I was using version 1. If you don't want to use Nu. Get (why?) download zip file from project's website and add reference to Html. Agility. Pack. dll file suitable for your platform (zip contains separate versions for . NET 4. 5 and Silverlight 5 for example). Documentation in . When I opened downloaded file (in Windows 7), the documentation looked empty. You have to create Html. Web object and use its Load method with page address: Html. Web html. Web = new Html. Web(). Html. Document html. Document = html. Web. Load(. For example, it is possible to indicate whether cookies should be used (Use. Cookies) and what should be the value of User Agent header included in HTTP request (User. Agent). For me. Auto. Detect. Encoding and Override. Encoding properties were especially useful as they let me correctly read document with Polish characters. Html. Web html. Web = new Html. Web() . With it you can check the result of latest request processing. Having Html. Document object ready, you can start to extract data. Here's an example of how to obtain links addresses and texts from previously downloaded webpage (add. System. Linq): IEnumerable< Html. Node> links = html. Document. Document. Node. Descendants(. Method. Descendants is used to retrieve all links (a tag) that contain. After that texts and address are printed on the console. Few other examples: Getting HTML code of the whole page: string html = html. Document. Document. Node. Outer. Html; Getting element with . Simple condition: Where(x => x. Name == ! Firstly there is no guarantee that each. Null. Reference. Exception exception. Secondly the check for toclevel- 1 is flawed. HTML element might have many classes, so instead of using == it's worthwhile to use Contains(). Plain Value. Contains is not enough though. What if we are looking for ? Such element will be matched too! Rather than Value. Contains you should use Value. Split(). Contains. This way an array of strings will be checked via equals operator (instead of searching a single string for substring). Getting texts of all li elements which are nested in minimum one li element: var h. Texts = from node in html. Document. Document. Node. Descendants(). Name == . For example: Getting a tags that have href attribute value starting with # and longer than 1. IEnumerable< Html. Node> links = html. Document. Document. Node. Select. Nodes(.

These topics are beyond the scope of this post. While processing consecutive pages, dump useful information to local database most suitable for your needs. Maybe. . csv file will be enough for you, maybe SQL database will be required? For me plain text file was sufficient. Last thing worth doing is ensuring that scraper properly logs information about its work progress (for sure you want to know how far your program went and if it encountered any errors). For logging it is best to use specialized library such as log. There's a lot of tutorials on how to use log. I will not write about it. But I will show you a sample configuration which you can use in console application: =. The first logs text to console window, ensuring that errors are clearly distinguished by color. To reduce amount of information. Level. Range. Filter is set so only entries with. INFO or higher level are presented. The second appender logs to text file (even entries with. DEBUG level go there). Maximum size of singe file is set to 5. MB and total files number limit is set to 1. Current log is always in Log. And that's all, scraper is ready! Run it and let it labor for you. No dull, long hour work - leave it for people who don't know how to program : )Additionally you can try a little exercise: instead of creating a list of all pages to visit, determine only the first page and find a link to next page in currently processed one.. P. S.: Keep in mind that HAP works on HTML code that was sent by the server (this code is used by HAP to build document model). DOM which you can observe in browser's developer tools is often a result of scripts execution and might differ greatly form the one build directly from HTTP response. Update 0. 8. 1. 2. As requested, I created simple demo (Visual Studio 2. Html Agility Pack and log. The app extracts some links from wiki page and dumps them to text file.
