Sub-Extractor Patterns
Overview
Sub-extractor patterns allow you to extract data within the context of an extractor pattern, providing significantly more flexibility in pinpointing the specific pieces you're after. Please read our documentation on using sub-extractor patterns before deciding to use them.
Sub-extractor patterns only match the first element they can. To get multiple matches, you would use manual extractor patterns instead.
Managing Sub-Extractor Patterns
Adding
- Click the Add Sub-Extractor Pattern button in the sub-extractor patterns tab of the extractor pattern.
Removing
- Click the Delete Sub-Extractor Pattern button in the main pane of the sub-extractor pattern in the sub-extractor patterns tab of the extractor pattern.
