Hi, In the Apache Tika project [1] we use SAX quite a lot, and have written a set of quite useful general utility classes for SAX handling.
For example, in org.apache.tika.sax [2] we have the following: * ContentHandlerDecorator - Convenient base class for writing ContentHandler decorators * EmbeddedContentHandler - Decorator that blocks startDocument() and endDocument() calls * TeeContentHandler - Forwards SAX events to multiple handlers * TextContentHandler - Decorator that blocks everything but character events (and start/endDocument) * WriteOutContentHandler - Writes the contents of all character events to a Writer In org.apache.tika.sax.xpath [3] we have a simple XPath subset implementation that supports streaming and filtering of SAX events. In other words, the implementation doesn't need a DOM tree to evaluate XPath statements. I believe this code would be useful also outside Tika, and I was thinking that it might perhaps make sense to create a Commons project for this. I also know of some SAX processing classes in Cocoon and Jackrabbit that could well be of interest to a wider audience. Do you think something like this would be interesting as a Commons project? Are there other similar efforts that I should know of? I looked at XML Commons in xml.apache.org, but it seems pretty dormant.
