Repeating Content

Content itself can be generated based on the structure of a press file's data using a <repeat> directive.

The repeat directive can either loop over a data reference by setting the data attribute, or a flow group by setting the group attribute.

The repeat will iterate over the contents of the data reference, assigning this value to a new local variable whose name is provided by the repeat's optional item attribute.

For example,

<press>
    <document format="a4">
      <page>
        <repeat data="data.people" item="person">
          <h1>Hello, {{ person.name }}</h1>
        </repeat>
      </page>
    </document>
    
    <data type="json">
      {
        "people": [
          {"name": "Bob"},
          {"name": "Alice"}
        ]
      }
    </data>
</press>

would create a page with two titles, one greeting Bob and another greeting Alice.
