Subject: Re: [xsl] figuring out what grandparent(?) is From: "Joerg Heinicke" <joerg.heinicke@xxxxxx> Date: Fri, 29 Mar 2002 14:34:08 +0100 |
Hi Eric, here the normal template: <xsl:template match="link"> </xsl:template> So the context node is <link>. Then there are two ways to test on the grandparent. Either with name() or with a specific axes and test whether the nodeset is empty or not. 1. name() <xsl:if test="name() = 'link' ">the name of the current node is 'link'</xsl:if> name() without parameter returns the name of the context node. name() with parameter returns the name of the first node in this nodeset. So name(//*) returns the name of the first element in the whole document, which should be the root element. For your example you need to select the grandparent from the current node. The easiest thing is '../..' (two steps up). So name(../..) should give you 'article' or 'smallbox' and you can test on it. 2. axes/nodeset The other way is using axes. You can find a list of them here: http://www.zvon.org/xxl/XSLTreference/Output/index.html. For your problem parent and ancestor(-or-self) are the important ones. You can use the axes with name() too: name(parent::*/parent::*) is the same as name(../..). But I want to show you another way testing on the nodeset directly. You must specify the name exactly instead of using parent::*: <xsl:if test="parent::p/parent::article">the grandparent is named 'article'</xsl:if> The XPATH expression parent::p/parent::article returns a nodeset with all nodes, (which are grandparent of the current node and which are named article and (which have a child p, which is the parent of the current node) ). It's a bit difficult to write it from the eyes of 'link'. The grandparent can be only one node and so the returned nodeset can only contain one node or no node. This is converted to boolean false or true and so you can use it for your test. Hope this helps, Joerg > Simplified, part of my XML looks like this: > > <article> > <p> > <link/> > </p> > <smallbox> > <p> > <link/> > </p> > </smallbox> > <article> > > When processing the <link> template, I need to know whether I'm inside of > the <smallbox> or just in the <article>; that is, I need something like: > > <xsl:choose> > <xsl:when [descendant of smallbox]> > do this > </xsl:when> > <xsl:otherwise>... > > Explanations on the beginner level please!
