OK - I just failed to grok that method when I scanned the docs. Thanks.
Should there be a similar method in SAXBuilder for reading docs where
one knows newlines are meaningless - I have larg-ish data docs that
have elements with either children or text content and whitespace is
always irrelevant excepty for readability. I'd like to silently avoid the
thousands of extra String("\n") that would be included with things like
That is, if I read a pretty XML file, I know I don't want the (3?) strings of
"\n" in the content list - even if the strings are interned, that is still 3
LinkedList nodes referencing them/it.

The indent art is currently a String (typically " " or "").
I'm not that keen on method signatures like (boolean,boolean,boolean)
since it is always hard to recall what order things are in. Something
like (int,int) is OK for position because everyone takes it as (x,y).
For convenience of writing the code, it seems that
would suffice. If someone wants to actually tune the output precisely, making a
few method calls is not too much to ask. Maybe pretty would give trimText,
newlines, indent of 2-4 spaces, and a line-break after 80 chars.
