Introduction
Plugin for extracting data from websites. It's a great tool for marketers, store owners, and more. With its help, you can easily analyze the availability of products from competitors, monitor price changes, etc.
Using the web parser, you can quickly download product catalogs with the required characteristics. This feature will help you optimize your work with large amounts of data.
Note: A website made on Bubble.io (and some other websites) cannot be parsed with this plugin.
Important
We cannot guarantee successful parsing of some pages. Many marketplaces or just large projects use protection against bots and parsing.
Attention: Pages made on bubble.io (and possibly other no-code projects) cannot be processed due to the peculiarities of their system.
How To Setup
Place the Page Preview element on the page.
One Page Parsing
- Place an input element on the page. A link to the page that we will process will be entered in this field.
2. Place a PagePreview element on the page. In this element will be placed content of the parsed page.
3. Add a new workflow. You need to pass the link to the plugin action "Web Page Parser - Get HTML From One URL"
4. Set 2 states of our PagePreview element:
5. Passing states to our element.
6. For further actions, we need 3 data tables.
- Data table for templates with one field: Title ( type: Text )
- Data table for template fields: 1. Template ID ( type: Text ) - Here we will store the template id from the Templates table. 2. Class List ( type: Text ) - Here we will store data about the position of the field on the parsed page. 3. Title ( type: Text ) - Here we will store the title of the field.
- Data table for fields selected direct from PagePreview element: 1. Title ( type: Text ) - Here we will store the title of the selected field. 2. Text ( type: Text ) - Here we will store the text content of the selected field.
7. Add new workflow
For Collecting Data From Page
:::hint
Note: You can pass the name for the data as you like (for example, do everything through a popup with an input field)
:::
For Creating Template
- Need to create a template
2. Add Field To Template
:::hint
We got the unique id directly from the database. You can get them from wherever you like, for example, as on the demo page, from the dropdown.
:::
Optional Functions
Finding tags on the page
- Add a dropdown to the page
2. Add a new step in the workflow.
3. Create a new state
4. Set value of this state
5. Set the source of the dropdown to this state
6. Add a new workflow
Now on change a tag in the dropdown, all elements of the parsed page with this tag will be highlighted
Multiple Page Parsing
If the page was opened with single parsing, it is not a fact that with multiple parsing, requests will not be blocked for incomprehensible activity from IP.
For multiple parsing of pages, you need at least 1 template and a CSV file with links. Due to differences in the HTML code structure, the same template can't be used for different sites.
Example of correct .csv file: Download
- Place a file uploader on the page
2. Add a new workflow
3. Add action from the plugin
5. Set link from the file uploader
6. Add step in the workflow
7. Set data of action
The template can be chosen in any way convenient for you (see demo page).
8. Now return data in a convenient format
- As link to .csv file with data
- As formatted text
