Collected data

Content
Server response code
Server response description
Server response headers
Proxies used during the request
Array with all collected pages (used when the Use Pages option is active)

Capabilities

Multi-page scraping (pagination traversal)
Automatic proxy management
Success response validation by code or page content
Supports gzip/deflate/brotli compression
Detection and conversion of website encodings to UTF-8
CloudFlare protection bypass
Engine selection (HTTP or Chrome)
The option Check content – executes the specified regular expression on the received page. If the expression did not trigger, the page will be reloaded with another proxy.
Use Pages option – allows iterating through a specified number of pages with a defined step. The $pagenum variable contains the current page number during iteration.
The option Check next page – requires specifying a regular expression that will extract the link to the next page (usually the "Next" button), if it exists. Traversal between pages is carried out within the specified limit (0 - no limits).
Page as new query option – transitions to the next page occur in a new request. This allows removing the limit on the number of pages to traverse.

Use cases

Downloading content
Downloading images
Checking server response code
Checking for HTTPS presence
Checking for redirects
Listing redirect URLs
Getting page size
Collecting meta tags
Extracting data from page source code and/or headers

Queries

As queries, you must specify links to pages, for example:

Results processing

A-Parser allows processing results directly during scraping; in this section, we have provided the most popular cases for the Net::HTTP scraper

Outputting H1-H6 headers

Add regex (option Use regex) <(h\d+)[^>]+>(.+?)<\/h\d+>, in the "Apply to" field select $pages.$i.data - Page content, in the field opposite the regex select modifiers sg. An array will be automatically selected as the result type. In the "Name" field specify headers, then in "$1 to" specify tag, click on

plus opposite and in the appeared new field "$2 to" specify content. In the general result format, write the output $p1.headers.format('$tag - $content\n').

Collecting meta tags

Add regex (option Use regex) (<meta[^>]+>), in the "Apply to" field select $pages.$i.data - Page content, in the field opposite the regex select modifier g. An array will be automatically selected as the result type. In the "Name" field specify meta, in "$1 to" specify item. In the Result Format use $p1.meta.format('$item\n').

Pagination traversal options

Using Use pages

Use pages. This function allows traversing pagination by specifying a predetermined number of pages. For example, let's take one of the categories on the product catalog website https://www.proball.ru/catalog/myachi/. At the top and bottom, we see a pagination panel. When clicking on icons with page numbers, you can see in the browser bar how the parameter with the page number is passed at the end of the request:

https://www.proball.ru/catalog/myachi/?PAGEN_1=1

Use pages - this is a kind of counter that actually substitutes numbers into the variable $pagenum in order, increasing them by the value we specify

As seen in the screenshot, the variable $pagenum. The function Use pages will iterate through and substitute all values into the query; effectively, we will be getting links for the request

https://www.proball.ru/catalog/myachi/?PAGEN_1=$pagenum

where instead of the variable $pagenum the page number will be substituted, starting from 1 up to 4 with a step of 1. Thus, a traversal through the pages of the required range is achieved. This is the limitation of this method - you need to know in advance the number of pages that exist in the pagination. Obviously, when scraping several categories simultaneously, the number of pages will be different everywhere, and as a workaround, we can simply specify a larger number of expected pages. But this is not entirely correct, so there is a more optimal solution, which will be discussed next

Using Check next page

Check next page - is another function that allows organizing pagination traversal. The peculiarity of its use is that to transition to the next page, you need to use a regular expression that will return a link to the next page. This is a more convenient and most frequently used method. But applying it for https://www.proball.ru/catalog/myachi/ will not work, as there are no links to next pages in the code. Links there are generated by a script. Therefore, let's take the website as an example http://www.imdb.com/search/name?gender=female. There is pagination both at the beginning and at the end of the list. After looking at and analyzing the source code, you can see the presence of a link that allows transitioning to the next page:

in the Next page RegEx field, we will write a regular expression
in the field Limit we will specify the number of pages to traverse

The example specifies 4. By specifying a limit, we define how many pages the scraper should traverse. In our case, 5 pages will be traversed, as counting starts from 0. If you specify a limit of 0, then the scraper will work until it traverses all pages regardless of their number. This is very convenient to use when you need to scrape all results from all pages

As mentioned above, it is possible to dynamically limit the number of pages in Use pages. To do this, you need to jointly use Use pages and Check next page. Let's supplement the example that was considered when describing Use pages and add the function Check next page:

These two functions work in pair as follows: Use pages provides page traversal, and Check next page checks if the next one exists. As soon as Check next page does not find the next page, scraping of this category will be stopped without waiting for the traversal of the entire quantity specified in Use pages. By combining these functions, we add efficiency to the scraper's operation, saving time and resources

Using substitution macros

Substitution macros allow implementing sequential substitution of values from a specified range

This preset will work as follows. By specifying a template in the query format:

$query?PAGEN_1={num:1:10}

we add substitution of values from 1 to 10 (any range can be specified) into the query itself. Thus, we get queries that provide traversal through the required number of pages, of the form:

https://www.proball.ru/catalog/myachi/?PAGEN_1=1
https://www.proball.ru/catalog/myachi/?PAGEN_1=2
...
https://www.proball.ru/catalog/myachi/?PAGEN_1=10

Using substitution macros for pagination traversal is similar to the function Use pages and has the same limitations, that is, you need to specify a specific range of values. The advantage of this method can be considered that through substitution macros you can substitute different values, both numerical and text, for example, words or expressions. Thus, we can more flexibly insert necessary parts into queries or form the queries themselves from parts that will be located in different files, if the task requires it

Using Page as query

To reduce memory consumption, the logic can be defined using the option Page as query. When activated, the Check next page and Use pages functions will substitute each next page into queries as a separate independent query, thereby not accumulating their content in memory. Page as query also allows defining whether to increase the query level Increase (similar to the operation of the tool tools.query.add), or not Keep
