I just realized that there is a bug in the solution that I mailed this morning. The period (.) is a special character meaning "any character". To indicate that we want a period and not "any character" the period must be escaped with a backslash, i.e., \. Here's the fixed solution: <datatype name="IP" source="string"> <pattern value="((1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])\.){3} (1?[0-9]?[0-9]|2[0-4][0-9]|25[0-5])"/> <annotation> <info> Datatype for representing IP addresses. Examples, 129.83.64.255, 64.128.2.71, etc. This datatype restricts each field of the IP address to have a value between zero and 255, i.e., [0-255].[0-255].[0-255].[0-255] Note: in the value attribute (above) the regular expression has been split over two lines. This is for readability purposes only. In practive the R.E. would all be on one line. </info> </annotation> </pattern> </datatype> xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
