Hi Tim, > Roger, all these corner-case explorations raise the question: what are > you up to anyhow? Inquiring minds want to know. I am writing an XML Schema regex for instance documents which may be used on many different platform. Prior to this discussion I assumed that the regex needed to account for every possible set of line break characters which could occur on the different platforms. Then I discovered that line breaks are normalized. But my instance documents used xml:space="preserve", so I needed to find out if that impacted line break normalization. Then I learned that xml:space="preserve" has no impact on line break normalizing. This is a long-winded way of saying, "in an XML Schema regex, the line break character is \n, regardless of the platform that the XML document is located on". /Roger
