How to output only specific fields from this filter?

[veeraraghavan-s]

Hi, Like we have include => in kv filter can we stop this filter output to specific fields/keys alone ? I can't find an include or an equivalent attribute in the documentation?

You can use the xpath setting to select a part of the xml to store in a specific field: https://www.elastic.co/guide/en/logstash/current/plugins-filters-xml.html#plugins-filters-xml-xpath
