Dear Sir, I'm very much delighted to let you know that i did data scraping with PHP-cURL, PhantomJS, Node.js, Selenium from many sites. I just scraped the data from web site and then wrote the data in mysql database or excel or csv or xml file. I worked on many similar projects, I have big experience in data mining projects. I have written hundreds of web scrapers which scrape millions of pages each day. I'm ready to fulfill your requirement. I can finish this task in short time, with the best quality. I can assure 100% accuracy. Please give me the opportunity to do the work. With Kind Regards, Debdulal Roy Proshanta

Hello, let me tell you the technology & library I will use. I will use C# programming language I will use HtmlAgilityPack to parse HTML code. There is a problem is that -> the library will not work if the page contains dynamic fields (fields generated by javascript) As what you said in your job description. I guess: 1, The step#1 is a listing page -> search by some keywords then return a list of search result, every search result has a like to view detail (or similar thing, for example, show more etc) What the first step to do is to scrape these links and save into a list. 2, The step#2 is to visit these detail page to scrape real data you want to save, correct? I want to know how to save these data, include the photo? Do you want to save these fields into csv or database? Do you want to save the photos into a local directory? There are 2 most common problems for scraping project: 1, Captcha -> does the website use Captcha? 2, IP Block -> Will the website block IP address if we send too many requests to the web server? I hope I can work on your project, so please contact me, let's talk! I am here waiting for your message. Thank you!

Hello! I am a professional programmer with many years of web scraping experience using Python. I have read your project description, and I can create the web crawling program you require. To do so, I will use the libraries BeautifulSoup (for parsing html) and Selenium (for working with AJAX or Javascript, if necessary). I have written very similar programs in the past, and I would be happy to show examples. Please contact me so we may speak further and so I can send files. Thank you for your consideration.

Webcrawlers are one of my favorite projects to work on because of how simple they are. The algorithms aren't complex. Just recursive scanning of tree structures. They're almost... soothing to work on. I'd use Python for this. I can produce output for you in CSV, json, XML. Or if you have a custom format, just ask. If you have any questions, let me know.

Hi there, I am an experience java developer with more than 3 years experience in enterprise field. I do have experience with scrapping tools: the most challenging one being scrapping an online movies sites; I have to take each one by categories and go get all the details as well as thumbnail, afterwards saving the actual movie on my local drive. I can do this in a couple of hours, just let me know if you want the code only or just the output (or both of them). Please give me the link and a sample and I will do this in a timely manner. Looking forward working with you, Ioan
