How to get each file's name in a fileset?

[Ding Shukai]

hi,
In my project, the ant buidfile needs to know each file's name in a fileset.
For example, there exists some files like XXX.wsdl in the schema dir; if
I could get the string XXX, which is a porttype name, then I neednot to
specify the porttype names in build.properties. Could anyone Help me,
please? Thanks~
