RE: Set variable via contents of <variable> element
> As I understand it, I can set the value of a variable in two ways: > 1. By the "select" attribute of the <variable> element: > <xsl:variable name="myvariable" select="'myvalue'"/> > > 2. By the contents of the <variable> element: > <xsl:variable name="myvariable"> > My value > </xsl:variable> Which have completely different effects. In the first case, the value of the variable is a string. In the second it is a tree of nodes: a document node, with a text node child containing the string "My value" (plus surrounding whitespace). Incidentally the second form can be dramatically slower than the first. > > But how do I set the variable using the second method? In XSLT 1.0 you can't. In XSLT 2.0 you could use <xsl:variable name="x" as="node()"> <xsl:sequence select="..."/> </xsl:variable> > > The reason I need to do this is because I want to set the > variable 'usethis' > to the result of a <choose> element which (as far as I know) > I cannot include in a "select" attribute. Yes, in XSLT 1.0 this is a problem. Sometimes a workaround is to use <xsl:variable select="expr1[condition] | expr2[not(condition)]"/> which is equivalent to the XSLT 2.0 <xsl:variable select="if (condition) then expr1 else expr2"/> Regards, Michael Kay http://www.saxonica.com/ http://twitter.com/michaelhkay
