matching simple XPaths with XPath expressions

[Nikolaos Giannadakis]

Dear all,

is there any way I could check whether simple Xpath expressions (such as
/A/B/C ) are instances of more complicated XPath expressions (such as //C),
using the xalan API?

For instance, /A/B/C is an instance of /A//C,
while /F/C is not.

thank you,
