This article is written to help you quickly understand how to parse data using the iDatica extension . The article is designed for people who are not familiar with XPath and CSS. We will consider a little theory and basic (for data parsing) syntax that will help you understand how to collect data from the vast majority of sites.

Using Xpath for Parsing
First of all, you need to understand what costa rica telegram database Xpath (XML Path Language) is – it is a language for querying elements of xml markup. This means that by sending a request composed in a certain way, you receive the necessary data in response. A simple analogy is an address in the browser line or a path in the explorer to the desired folder, by typing the correct path you get to the desired site or the desired folder. With Xpath it is the same – we write the path and get to the necessary data, only unlike the browser line, we use Xpath for searching. And in our case, for searching by xml documents in html format, in other words, by the code on which the site is built.

If you right-click on an empty space on the site and select “site source code” or “view page code” in the context menu (it varies in different browsers), you will end up on the page with the code from which the parser extracts data.
