Hi Vincent, The ExtractHandler listens to SAX events in order to obtain a well- formed XML fragment with the following semantic: xmlInput.dropAllTags().substring(start, length).unDropAssociatedTags() So basically you would create an instance like: new ExtractHandler(0, 400) in order to obtain an XML fragment with its inner text length of at most 400 characters, starting at position/character 0 in the source/input XML's inner text. The ExtractHandler is currently used in http://tinyurl.com/6pcn6e to obtain a preview of an XML (HTML, to be more specific). Another use case I can think of is to paginate an XML source (keeping pages well-formed). To give you an example, the result of applying an ExtractHandler(3, 13) to: <p>click <a href="realyLongURL" title="Here">here</a> to view the result</p> is: <p>ck <a href="realyLongURL" title="Here">here</a> to</p> I'll improve the javadoc on Monday.
