Using two parsing levels to extract information from unstructured data

This scenario applies only to Talend Data Management Platform, Talend Big Data Platform, Talend Real-Time Big Data Platform, Talend MDM Platform, Talend Data Services Platform, Talend MDM Platform and Talend Data Fabric.

This scenario describes how to build a set of rules to extract some information from unstructured data. It explains how to use a basic ANTLR rule to tokenize data then how to use an advanced rule to check each token created by ANTLR against a regular expression.

This scenario uses:

• a tFixedFlowInput component to create the unstructured data strings.

• a tStandardizeRow component to define the rules necessary to extract the liquid amounts from the data strings.

• a tLogRow component to display the output data.
