Hi Rob, Whitespace outside an element is inside of another one (except for whitespace outside of the root element). Whether this whitespace is "ignorable" depends on your application and/or whether you have a grammar which declares that the content of an element is only other elements.
The "include-ignorable-whitespace" and "element-content-whitespace" features have the same behaviour, however they only apply to DTDs. If you have no DTD then I suggest that you use an LSParserFilter. This has come up before on this list. May want to take a look at the previous discussion [1] in the archives. Thanks.
