Subject: RE: [xsl] trying to set a parameter equal to an elements attribute From: "Dion Houston" <dionh@xxxxxxxxxxxxx> Date: Wed, 21 Aug 2002 14:55:27 -0700 |
Well, actually there are even more issues with the example: <header volume="8"/> <xsl:param name="vol"> <xsl:value-of select="header[@volume]"/> </xsl:param> OK, first of all in a simple case like this, you probably don't want an RTF, although it'd work... So the first step is to add a select: <xsl:param name="vol" select="header[@volume]"/> The second issue is in the XPath... note that the end result of the above XPath is a _header_ node (header[@volume] means all header nodes which have a volume attribute), not the volume attribute. Therefore, when you use it as a number, it's going to take the text content of the header element, which is empty. What you probably intend is: <xsl:param name="vol" select="header/@volume"/> In this case, you're going to assign the volume attribute to the variable. As a matter of preference, since you're using this as a numeric value, I'd go ahead and case it: <xsl:param name="vol" select="number(header/@volume)"/> Because of the semantics of nodesets in different places, this can sometimes keep you out of trouble. HTH!
