# Page processors

### What should I know about page processors?

*Page processors* determine how your crawler behaves. Without page processors, your crawler does nothing more than visit every page on the Web site. No information will be extracted. A crawler can have as many page processors as your requirements dictate.

Each page processor is made up of two sections: *conditions* and *actions*.

#### Conditions

*Conditions* determine whether a given page processor is executed for a page. All page processors are checked against every single page the crawler visits and if they match, the configured actions are applied.

You can add any number of conditions to a page to ensure it matches only the exact pages you want it to. All defined conditions for a page processor must be true for the actions to be applied to the given page.

- **Match every page**: All pages are affected by the configured actions
- **Contains element**: Allows jQuery selector
- **Does not contain element**: Allows jQuery selector
- **Does not match URL**: Accepts a regular expression that is matched against each web page URL
- **Matches URL**: Accepts a regular expression that is matched against each web page URL

#### Actions

*Actions* direct the crawler's activities upon visiting a page matching the associated conditions. Actions allow extraction of data, the addition of URL's to the crawl list, and more.

- **Extract element contents**: Accepts jQuery selector, output field, and regular expressions to match several values or to format the output
- **Extract element attribute**: Accepts jQuery selector, attribute name, output field, and regular expressions to match several values or to format the output
- **Extract URL referring to page**: Accepts output field
- **Extract page title**: Accepts output field
- **Extract page URL**: Accepts output field
- **Add URL attribute to crawl list**: Accepts jQuery selector, attribute name, and regular expressions to match several values or to format the output
- **Remove elements**: Accepts jQuery selector
- **Don't follow any links on page**: Crawler will not follow links from the page
