The difference is that you were creating a Result Tree Fragment (RTF), which is not the same as a node-set. All you can do with an RTF is <xsl:copy-of/> and <xsl:value-of/>. The idea is (was) that you can create an RTF as the value of a variable and re-use it throughout your stylesheet. For example, in HTML you might have some special code to output a bullet point with pretty graphics, and you want to re-use that code with the exact same <img> tag. You cannot select children of an RTF. To do that, you have to convert it to a node-set. Processor designers realized the pain of doing this, so they provide xxx:node-set() functions to do the conversion. Unfortunately, the functions are not compatible between processors, so you will have to do some tricks if you want to use more than one processor. > With the example I do not need any conversions between anything. Well, go complain to the XSLT 1.0 designers :). XSLT 2.0 doesn't have this problem, since so many people like yourself have complained. I believe that Saxon 7.0 is the only browser that supports XSLT 2.0. You can go try that, get RTF to node-set conversion, and a bunch of other new features for free. - -- Peter Davis -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE9uYJchDAgUT1yirARAjWNAJ4tJosh6Gu8Pjiq96JF1ZhmTQ0EPwCghuKW ofFSnBSdfKZBb0GgoMqWd4Y= =ck0v -----END PGP SIGNATURE----- XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
