Twitch - Chat Extraction from Snapshots

Overview

When automating Twitch with browser automation, chat messages are stored in a specific structure within the accessibility tree. This guide explains how to extract chat message content.

Chat Message Location

Chat messages are stored in the log container within:

1. complementary "Right Column"
2. complementary "Stream Chat"
3. region "Stream Chat"
4. generic "Chat messages"
5. log (actual chat log list)

Message Structure

Each message is a generic node with the full message in its accessible name:

generic "username: message content..."

Regular User Message

generic "username: Hello everyone!"
  └─ generic
       ├─ button "username"
       ├─ text: ":"
       └─ generic: Hello everyone!  ← message body

Broadcaster Message

generic "broadcaster_name: Welcome to the stream!"
  └─ generic
       └─ generic
            ├─ button "Broadcaster badge"
            ├─ button "broadcaster_name"
            ├─ text: ":"
            └─ generic: Welcome to the stream!  ← message body

Extraction Methods

Method 1: Search by Username Pattern

Search for the parent generic node's accessible name:

Search pattern: "username:

This returns the full message including content.

Method 2: Navigate Tree Structure

For detailed message structure, navigate the accessibility tree from the chat log container to find individual message nodes.

Key Points

• The parent generic node's accessible name contains the full message: "username: message"
• Older messages may have timestamp prefix: "Sent at 1:40, username: message"
• The actual message text is in a child generic node after text: ":"
• Broadcaster messages have deeper nesting due to badge elements

Common Issues

• Summary view limitations: Default output may only show buttons/links, not message text
• Solution: Navigate the full tree structure, or search for "username: pattern to get full message content
