There is such a task to parse the data from the selling site ads. The problem is that there is a whole set of search and filtering options, and you need to parse in such a way as to move from large to small. For example, phones, then the phone brand, then the year of manufacture of the phone, respectively, the sample is reduced. All these data on the number of products, reviews and customer ratings should be pulled from the site. Because the second question to the professionals, it is better to do this through the application or through your site, which will merge the data from the selling information? Are there any ideas, tips, suggestions on this? I would appreciate informative helpful answers.

  • link to the site can throw? or is there a closed registration? - Sergey Rufanov
  • one
    First tip: try to arrange a site for information. The second tip: understand that the syntax analysis is here no matter what side ... And third: explain (first of all to yourself, well, to us at the same time): what is meant by "through the application or via the website"? - user6550 pm
  • @SergeyRufanov Rufanov, there are a lot of sites-ads that need to be analyzed. For example, Avito. - IntegralAL
  • @klopp, parsing, it was not me who put it), someone corrected my question, so it’s not a complaint to me. The third question, that is, either through a web interface, to implement such, for example, to pull data from another site on php, or on C #, delphi write an application that, for a given link, will also pull the desired values. So I ask for advice from those working in this area. - IntegralAL
  • I still do not understand why if on php, then this is a "site", and if in C #, then an "application" :-) Anyway, little things. Look for an HTML parser for your language and go ahead. Here their discussions are tons. - user6550
