Dear Dr. Kay,
Of course!! I forgot that wonderful trick of the null document() function that allows the program to see itself. If those old Zen masters had had XSLT they would not have been in such a lather about the the self seeing the self. Thank you very much indeed. David Riggs Nichibunken, Kyoto --- original message--------- From: "Michael Kay" <mike@xxxxxxxxxxxx> Well, there aren't many programming languages that allow a program to read its own source code, but you're in luck, because XSLT is one of them. <xsl:value-of select="document('')/*/xsl:variable[@name='bool']/@select"/> should do the trick. The alternative solution to this problem is to have the search conditions supplied as a string (for example in a stylesheet parameter or a configuration file) and to use dyn:evaluate() to turn the string into an expression that you can evaluate.
