That may be the behaviour of a particular implementation but it isn't a characteristic of the API. You could ask about what the Xalan implementation does internally on one of the Xalan mailing lists. > I am not sure, but in the > beginning I was using an API which consumed so much memory because > of many xpath evaluations.

Whatever works for you... Just keep in mind that this API is specific to Xalan while the other is supported by Java 5 and all JAXP 1.3 implementations. > To be honest, I'm a bit confused: I think I'm using XALAN, though I > don't need XSLT.
