Extracts data from web pages using browser automation and CSS/JavaScript selectors. Use when you need to scrape titles/text/structured fields from live web pages or when the user mentions scraping, extraction, or selectors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Web Scraping Skill
## Description
Extract data from web pages using JavaScript and CSS selectors. This skill uses real browser automation to navigate to pages and extract content using JavaScript execution. It can extract webpage titles using `document.title` and body text using `document.body.textContent`, providing actual content from live web pages.
## Dependencies
None
## Parameters
| Parameter | Type | Required | Default | Description |
|-----------|------|----------|---------|-------------|
| url | String | Yes | - | The URL of the web page to scrape |
| selector | String | Yes | - | CSS selector to target specific elements |
| attributes | List<String> | No | ["text"] | List of attributes to extract (e.g., "text", "href", "src") |
## Return Value
Returns a `SkillResult` with the following data structure:
```json
{
"url": "string",
"selector": "string",
"attributes": ["string"],
"data": "extracted content"
}
```
## Usage Examples
### Basic Text Extraction
```kotlin
val result = registry.execute(
skillId = "web-scraping",
context = context,
params = mapOf(
"url" to "https://example.com",
"selector" to ".content"
)

How to install
mdr add platonai/browser4/web-scraping@sha256:662274e5d2e2cd09The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
