Advanced ECL (Part 2): Super Files, Working with XML, Free-Form Text Parsing, and Machine Learning
This course explores the concept of Super Files in ECL and the techniques for working with XML data, getting it into your HPCC Systems cluster, and defining it to work with other data elements. This flows naturally into the detailed ECL support of Natural Language Parsing – creating pattern-matching definitions and using the PARSE function to extract data from either XML or free-form text.
Topics Include:
- SuperFiles and SuperKeys
- Simple XML Spray and Dataset Definition
- Working with XML Data (simple, complex, and nested)
- Complex XML Spraying and De-spraying
- PARSE with XML Data
- Spraying and defining free-form text data
- PARSE with free-form text
- New! An Introduction to Machine Learning
