I am receiving an html document as a http response. Is there a way (using ktor or kotlinx html) to parse that response into a document and then extract _csrf from it?
I am already using Jsoup for that. but, I want to know if there is another way using kotlinx html or ktor client

Ktor, like most HTTP clients, doesn't have a built-in DOM parser. Jsoup is an excellent choice. However you could integrate it via an interceptor so that the extraction of the _csrf value is done transparently. In Ktor this would require a custom plugin that hooks into onResponse or maybe transformResponseBody. You would still probably use the same Jsoup code but by embedding it into the plugin, it would happen automatically upon every response (or only specified paths/endpoints). In http4k this would be an additional HttpHandler in the pipeline. Other clients have the same concept, usually called an "interceptor" or "filter".

I'd use JSoup.
