the context of the following-sibling following a preceding-sibling should result you in the context of the current sibling?
The short of it is, I am comparing the preceding-sibling with the current. The preceding-sibling must contain the code "XYZ" when the current contains the code "WXY".
If you talk about "content", be aware that looking up elements both in the preceding-sibling and the following-sibling axis are likely to produce node sets, and the stringification of a node set will result in the string value of the first element in document order. An example XML <foo> <bar>1</bar> <bar>2</bar> <bar id="3">3</bar> </foo> The statement <xsl:value-of select=" /foo/bar[@id='3']/preceding-sibling::bar /following-sibling::bar"/>
Will get you a 2, not a 3 as you might expect. If in doubt, use a position predicate <xsl:value-of select=" /foo/bar[@id='3']/preceding-sibling::bar /following-sibling::bar"/>
