Re: "vertical slices" of tree

[Richard Cao]

Hi,

The "vertical slices" you are referring to are called siblings. This is
more apparent if the tree structure is written as

              a
             /   \
            b   e
           /       \
         c         f
         /           \
       d             g


To retrieve the siblings of a node, you can refer to the documentation on
the various axes [1].
Here is a simple example to print the siblings of <e>. In this case, we
want to use preceding-sibling and following-sibling.

<xsl:template match="e">
        <xsl:for-each select="preceding-sibling::*" |
following-sibling::*">
                <xsl:value-of select="name(.)"/>
        </xsl:for-each>
</xsl:template>

Hello,

Say I have the following tree:



<a>
             <b>
                         <c>
                                     <d/>
                         </c>
             </b>
             <e>
                         <f>
                                     <g/>
                         </f>
             </e>
</a>


If I'm calling this into the stylesheet via document():

             - How do I get the names of all elements on the same "vertical
slice"
that <b> and <e> are on?
             - or the names of all the elements on the same "vertical
slice" as <c>
and <f> ?
             - or the names of all the elements on the same "vertical
slice" as <d>
and <g>?

Note: the names of the elements aren't static so I can't just specify a
static path to anything.

Any ideas?
TIA
