Precompiling XPath expressions without a target document

[Taras Tielkes <ta...@info.nl>]

Hi,

I have a couple of XPath expressions that I want to evaluate over and over
again, but on different target xml documents.

I took the code from XPathAPI.eval(), and plugged in a custom implementation
of the PrefixResolver interface that just does static lookups from a table
of static prefixes and namespaces. (Since I don't have a Document reference
at the time I compile the XPath expressions.)

Is this a sane use of the available APIs, or should I take a different
route?

Thanks,

// tt

This is using PrefixResolver as intended.  You're doing things the right
way.
