I want to be able to filter any whitespace or carriage return types outside of xml elements.
I need this to be able to successfully use W3C DOM method Node.isEqualNode() to compare the elements and attributes of Documents with identical elements and attributes but which have differing amounts of white space - e.g. indentation is different, tabs instead of spaced, or documents produced on different platforms Unix / Windows where carriage-return, line feeds vary. This relates to the thread http://www.nabble.com/How-to-compare-Documents--Existing-library-method-available--or-use-DOMTreeWalker--td20856968.html If I use isEqualNode on 2 Documents that have identical Elements and Attributes but which have whitespace that varies (as described above), the Documents are still regarded by isEqualNode as different. I have done some searching and found three (3) options: 1) http://apache.org/xml/features/dom/include-ignorable-whitespace feature setting - but this is applicable to javax.xml.parsers.DocumentBuilderFactory - I am using and wish to remain using LSParser which is produced by DOMImplementationLS which does not have the setFeature method. I think the problem here is that LSParser is written to comply with W3C DOM interfaces and DocumentBuilderFactory is JAXP interfaces: how can I connect the two so that I configure the LSParser via the DocumentBuilderFactory setFeature method? 2) The LSParser is configured with a DOMConfiguration instance, and there is an option: "element-content-whitespace" true [required] (default)Keep all whitespaces in the document. false [optional] Discard all Text nodes that contain whitespaces in element content, as described in [element content whitespace]. The implementation is expected to use the attribute Text.isElementContentWhitespace to determine if a Text node should be discarded or not. BUT I'm not concerned with whitespace *within* the elements. I'm only interested in whitespace outside of elements, as explained above. 3) LSParserFilter interface - this seems like the most suitable solution but I have seen *NO* implementations of this interface searching the web. I also have bought O'Reilly Java and XML book edition 3 and there is no mention here either. Thoughts please on the above.
