Hi, @renow
In Launch, I'd recommend creating a data element that scrapes the meta tag from the page, then reference the data element in the necessary rules. For example, with the meta tag from your question (<meta name='mymeta' content='myvalue' />), create the following data element:
- Name: mymeta
- Extension: Core
- Data Element Type: DOM Attribute
- CSS Selector (right panel): meta[name='mymeta']
- Use value of: Other Attribute: content
In your rules, you can reference the data element (%mymeta%) to populate props/eVars, send to GA, or any other endpoint you need.
