Re: [Htmlparser-developer] about page.getText()

[Derrick O. <Der...@Ro...>]

The Page you have hasn't had any characters read from it yet (it's 
character offset is zero), hence it hasn't asked the source for any 
characters, hence the source isn't ready yet, and has nothing available 
yet. The ready() method is to check if the next read() may block, so it 
can't check if there are characters in the stream or URL provided. The 
getText() method with that signature returns all the  text read so far, 
in your case nothing.

Try:
Cursor c = new cursor (parser_page, 0);
do
{ }
while (0 != parser_page.getCharacter ());
System.out.println("parser_page.getText()="+parser_page.getText());

This is all explained in the javadocs.
