# Use DT syntax to get select keys from a list of dictionaries

DT syntax is supported within the extend-context value. You can use DT to get select keys of interest from a command that returns a list of dictionaries containing many keys. For example, the findIndicators automation returns a long list of indicator properties, but you may only be interested in saving the value and the indicator\_type to minimize the size of the context data.

**Example**

1. Run the command **`!findIndicators size=2 query="type:IP" raw-response=true`**.

   You will see a list of two dictionaries containing 20+ items.
2. Use the following value for extend-context to save only value and indicator\_type into a context key called FoundIndicators:

   ```programlisting
   !findIndicators size=2 query="type:IP" extend-context=`FoundIndicators=.={"value": val.value, "indicator_type": val.indicator_type}`
   ```
3. Use the following value for extend-context to save only the incident name, status, and id to a key called FoundIncidents:

   ```programlisting
   !SearchIncidentsV2 id=<ANY_INCIDENT_ID> extend-context=`FoundIncidents=Contents.data={"name": val.name, "status": val.status, "id": val.id}` ignore-outputs=true
   ```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/xsoar-6-administrator-guide/6.13/learn-about-cortex-xsoar/customize-and-configure-cortex-xsoar/playbooks/extend-context/use-dt-syntax-to-get-select-keys-from-a-list-of-dictionaries.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
