I remember a comment some time ago on this . . . that attributes are descendents . . . wouldn't they be children? -- of their containing element node, or context element node. So the element can have attribute children. But, that an attribute cannot reference its own element context node as a "parent." This would be consistent with the post elsewhere today on this matching @ thread, that matching an @ does not match the element node that contains it. To do so one would have to do "*[@foo]", correct? So @ are children, but those children do not have parents? thanks, jr =-=-=-=-=-=-=-=-=-==-=-=-= John Robert Gardner, Ph.D. XML Engineer Emory University ------------------------------------------------------------ http://vedavid.org/diss/ "There is a difference between knowing The Path, and walking the Path." -Lawrence Fishburn/Morpheus > > May be this vocabulary is not consistent with the standards but having > this rough generalization in mind helped me a lot to understand how to > work with XSLT. > > > Have fun, > > Paulo > > > -----Original Message----- > From: owner-xsl-list@xxxxxxxxxxxxxxxx > [mailto:owner-xsl-list@xxxxxxxxxxxxxxxx]On Behalf Of Linda van den Brink > Sent: Friday, May 26, 2000 9:22 AM > To: 'xsl-list@xxxxxxxxxxxxxxxx' > Subject: RE: Matching Attributes with @ > > > > I thought that apply-templates was only applied to > > elements, so how is apply-templates applied to attributes ?? > > Or does this mean that apply-templates is applied to all > > child elements of ATOM that have an attribute called UNITS ?? > > If my last assumption is correct, then further to the last > > paragraph from the XML Bible extract above, does > > <xsl:apply-templates select="BOILING_POINT/@*"/> cause > > apply-templates to be applied to all BOILING_POINT children > > that have at least one attribute ?? > > Templates can be applied to all types of nodes (for examples see section 5.2 > of the XSLT spec) such as element nodes, text nodes, and also attribute > nodes.
