jerichojars : Java Archive Wrapper Supporting the 'jericho' Package

Contents of the 'Jericho HTML Parser' Java archive by Martin Jericho http://jericho.htmlparser.net/docs/index.html provided to support functions in the 'jericho' package.

As a result of using a Java library, this package requires rJava.

While the main intent is to use this with jericho, you can use it out of the box as-is (see below and the javadocs).

NOTE: Package version # reflects the version # of the included JAR file.

Installation
