I have very specific requirement, so wnatted to know whether it can handle it or not.

I have an element node with me and user will give xpath relative to the element to retrive to node(s) pointed by the xpath.

It should support attribute and regular expression.
pls. let me know what API(class) should be used for this?

Try org.apache.xpath.CachedXPathAPI
or
org.apache.xpath.XPathAPI.

Both will allow you to specify an XPath string and it will return what you have asked for. This may or may not be what you wanted.

XPath supports XPath strings, not Regular Expressions. There is a learning curve associated with XPath.

@David: That is a great characterization; I shall have to remember it.
