List processing

Table of contents

Description

Lists are mainly used to get lines of data from a text document or data records to a file. For example, you have a file with a list of URLs and you need to access them one by one, or you parse some values from the site and need to sort them, delete duplicates and save them to a file (for example, parsed e-mail addresses).

How to add a list to a project?

Open

How to add an action to a project?

Via the context menu Add action → Lists → List processing

Open

Or use smart search .

What is it used for?

• Adding and Retrieving List Items

• Removing lines and takes

• Linking to a file

• Getting the number of lines

• Mixing

• Sorting values

How to work with an action?

Select a sublist

Select part of the lines from the list.

1. We select the list with which we will work.

2. We indicate the function.

3. We indicate where the result will be saved.

4. Sublist filtering method
   a) Range - set the interval of lines to be selected.
   b) Elements without text - will select all lines that do not contain the specified text, you can use variables.
   c) Elements that do not match the regular expression are - search criteria using the regular expression.
   d) Elements containing text - will select values that contain the required text, you can use variables.
   e) Elements matching a regular expression are search criteria using a regular expression.

5. This field specifies the value corresponding to the item from step 4.

6. Lines that match the search criteria will be deleted.

7. If the list is empty, Zennoposter will follow the red line.

Add data from the list

Adding data from one list to another.

1. Choose a list with which we will work

2. Installing the function.

3. We indicate where the lines will be wrapped from.

4. In which position the result is placed - go back to the start , go to the end , to position.

5. If you have chosen to position, then indicate the line number or variable.

Add line

Adding a line to the list.

Get the number of lines

Getting the number of lines in the list.

   a) All
   b) Not containing text
   c) Not matching regex
   d) With value
   e) Containing text
   f) Matching regex

4. Variable for writing data after processing.

Get line

Getting a line with the ability to remove it from the list and write it to a variable.

1. Choose a list with which we will work

2. Installing the function.

3. Line criteria (you can specify a variable):
   a) Does not contain text
   b) Not matching regex
   c) First
   d) By number
   e) Random
   f) Matching regex

4. Delete line after taking

5. Put to variable.

Bind to the file

Linking the list to a file during project execution.

1. Choose a list with which we will work

2. Installing the function.

3. Select a file or specify a variable containing the path to the file.

4. If the file is missing in the specified path, Zennoposter will automatically create it.

Sort

Sort the list items in descending or ascending order.

3. Use the principle like numbers.

4. We set the type of sorting in descending or ascending order .

Save to file

Usage example

Let's imagine that you need to go through all the pages from the list, collect their names and put them in another list.

1. Create a List _1 with pages having previously linked it to the file.

2. We remove duplicates so as not to go to the page twice.

3. Create and link to the List _2.

4. Parse the necessary information from the pages to List _2.

5. Delete duplicates.

Thus, you can generate lists of necessary information for further processing or use.
