ANT: Replace String in file with Filename itself

Question

I have a situation where I need to scan through a large number of .xsd files, and replace an instance of a string with another string based on the file name of the current schema being examined.

For example: I wish to replace the string: 'DataSet' in file1.xsd with the string 'file1DataSet' I wish to replace the string: 'DataSet' in file2.xsd with the string 'file2DataSet' and so on until all schemas have been modified.

I would like to know if there is anyway to do this without using the ant-contrib for loops.

You could try the <replace> task if you have a generally good idea how many schemas you have. The <replaceRegex> might be able to do it without looping.

Ant isn't really a programming language where you can loop. If you can do everything in one pass, that's great, but once you start really manipulating files, Ant runs into limitations.

yes, I ended up caving around November 25th or so and used ant-contribs with a foreach target loop pointing to a pathconvert with a chainedmapper to extract the filename and a simple <replace file="${filelocation}" token="NewDataSet" value="${file.name}Type"/> statement.
