Of course, it depends on how you "come across" the element (it is an
element, not a "tag" - xslt does not see start and end tags at all, only
nodes in a tree).  If the current node actually is a figureAnchor, then
this should do the job -

<xsl:variable name='figure-to-get' select='@figures'/>
<xsl:apply-templates select='/figureGroup/figure[@id=$figure-to-get]'/>

I have used a variable to make it clear what is going on and to prevent
any confusion about which node will be evaluated within the square
brackets. You do not always need to use such a variable, but it can be
useful for clarity.

This will cause the template for a "figure" element to transform the
figure element.  I presume that is what you have in mind.  The FO part
is up to you and the template.
