Parsing_​the_​KNIME_​Forum

Parsing the KNIME Forum

This workflow demonstrates how to parse the KNIME Forum. We work in different stages. First we read the list of topics from the forum page. Then we handle different forum categories separately. In each category, we search for all topics that are newer than 9 days. (This limitation is done mainly to speed up the workflow.) If there is a next page available, we also take that into consideration. After parsing the different thread pages for the forum categories, we read all information for the individual topics.
