Re: [jxpath] optimize xpath query on xpath enabled containers
Dmitri, I'm still looking at the code, so I can't comment on a fix yet. What I had in mind in implementing an interface that signals the jxpath implementation that a context (or pointer or something) is able of evaluating queries which result in the parsed query structure to be passed to the context. HTH, Michael Michael, I believe, adding this type of delegation for query evaluation would require quite significant refactoring of JXPath. However, I could be wrong. Do you have a particular fix in mind?

Queries like [EMAIL PROTECTED] = ''test'] will be executed by looping through all nodes and testing if the expression is true for a node. Because my model supports queries itself, It would be much faster to query the model and have the model itself execute the query that will load only the nodes for which the expression is true. I saw a xalan integration in the code, possibly for the same purpose. Is there a way to extend jxpath with functionality that uses the model (or the nodepointer) itself to execute the rest of the query?
