Question

I have an html file on my local disk and would like to extract text from it using BoilerPipe.

The “getText” method from the class ExtractorBase accepts a reader, so I wrote:

FileReader fr = new FileReader("D:/myHTMLfile");
System.out.println(ArticleExtractor.INSTANCE.getText(fr));

But then I get an error pointing to this second line of code.

Any clue? Thx!

EDIT: the whole error msg is:

You need to add nekohtml-1.x.x.jar at classpath.
